Well, guess who came a-knockin' on my door this afternoon. I gotta tell you guys, nothing stretches out an hour-and-a-half train ride quite like knowing you have a beautiful new sexy toy waiting for you…
I've only had her hooked up for a few minutes so far, but I like what I'm hearing. My setup is desktop/nearfield, and I feel like I'm getting a better sense of spatialization/'soundstage' than I was with Sig 16, but… honestly it's really too early to make calls like that. But I'm currently listening to the GVSU NME's rather short performance of Riley's 'In C,' and… I'm very pleased.
Of course sound is the main consideration here, but my other initial thoughts are as follows… You can tell, reading what Vinnie writes about LIO, reading his thought process… but once you get it in your hands, you can really feel that it's a labor of love. This thing doesn't exist just to exist, it exists because Vinnie wanted something better.
It's big. I mean, physical specs on a website are one thing, and the size won't matter in most installations, but I'm using it as part of a desktop setup, and it's… like two Sig 16s! My poor Sig 16 is still sitting on the desk, dwarfed and disconnected (I needed her longer IEC cable…), and LIO just… owns the space now. Anyway, she's big, and rightfully so (6300f worth of capacitors, crazy space inside for modules… it's impressive she's as lean as she is!). I have to experiment with my desk arrangement a bit more.
Speaking of desk arrangements and using LIO as an out-of-place desktop amp, if you're close to LIO, you can definitely hear the relays click when the cap banks switch over. Not a huge deal, especially if you're the sort of nerd who has a soft spot for relays clicking, but again… might have me rethinking my desk arrangement… In a normal setup, I can't imagine most people would notice.
Capacitors! For whatever reason, you can set the display to show the voltage of the current cap bank. I don't know when this would ever be useful, but it's incredibly fun. Or, maybe I'm just weird. The cap bank switches over when it hits 19V, drained from ~23.2V. So, if you want to (and I do, for some reason), you can just watch LIO count down from 23 to 19 and start all over. When you first plug her in, you can't even do anything except watch her count up - bank a from 0 to 23; then bank b from 0 to 23… It could be maddening, but somehow watching the progress makes it very… zen…
The remote is the same remote as on Sig 16, only with way more buttons. What this means is that you could bludgeon someone with said remote if you had to. Also, the Sig 16 remote does control the volume level on LIO.
No complaints so far with the DAC. I'm used to two DAC setups - a Resonessence Concero HD (which failed on me multiple times, but I think I just got a bunk unit - I wholeheartedly recommend this amazing box), and a Channel Islands VDA-2 fed by a Halide Bridge. The Bridge would occasionally conk out on me, bit buggy. The VDA-2 was resolution limited, and very heavily focused on the analog end of the DAC. I don't think I'll attempt to sell it, because it is a very, very nice DAC, but it seems to serve a different purpose to me. Concero was a very honest DAC, very precise, and I feel the same from LIO's DAC. One nice thing in my weird use-case is that Concero ramped up/down upon receiving DoP packets, LIO… clicks briefly. Clicks are not my favorite thing, but ramping up and down for seconds between tracks is much, much more annoying. I get it, but the LIO approach works better for me. Most of my music is PCM, of course, but it's nice to know I can serve up DoP from iTunes and be happy. When receiving DoP packets, LIO shows the DSD rate on the Frequency display. Nice touch! Weird thing about the DAC - it appears to the system as if the digital attenuation can be adjusted from the computer, and it makes bleepy bloops if you try, but it doesn't actually adjust. I can see where it could be confusing, but I would not complain about digital volume control on the DAC.
I never trust stepped attenuators to have enough steps to really work nearfield (low levels), but LIO definitely does. Again, you can hear relays clicking away when you adjust volume, and again… that probably pleases me more than it should.
I'll report back after heavier listening… but as far as I can tell, she's a keeper. Good work, Vinnie… a spectacular achievement indeed!

Question: was there a design change in the tube stage, or am I going nuts? Originally I thought it was advertised as having two gain settings...
Got a little bit more listening in last night, really sounds great so far... not that I expected any less from you, Vinnie, but I feel like the DAC really shines compared to most 'built in' integrated DACs that I've heard.

Hi brh,
Thank you for your post!
Yes, LIO is a full-sized component (17.5"W x 13.5"D x 4.5" H) - and as you can see from the pics or by sliding open the top cover,
almost half of it is the PURE-DC-4EVR ultracapacitor supply. :weights:
LIO had definitely been a labor of love - and I'm really pleased to read that you get that impression. Thank you!
We (John Chapman and I) thought it would be fun to have a display mode where you view the voltage of the ultracap bank in use, and
when bank switching happens (usually every 5 to 10 minutes, depending on all the modules that you have and how loud you are playing),
there are indeed two relays that switch. One is used for switching the bank that powers all the LIO audio circuitry, and one is used for
switching the bank that is charging. I laughed when I read your post and you mentioned getting zen with it. :thumb:
Question: was there a design change in the tube stage, or am I going nuts? Originally I thought it was advertised as having two gain settings...
You are NOT going crazy - there was initially going to be a low/high gain switch, and the prototype had this. But with this new tube circuit design, the benefits of doing away with it (sonically) were quite large. The soundstage opened up big time, and the max output voltage increased and I swear the transient attack was better. On the bench, the bandwidth increased from the change and is now flat all the way up to around 110kHz before it starts rolling off. And the output impedance was lowered from around 775 - 1k ohm range to down under the 200 ohm range. Voltage gain is right around unity ("buffer"). As much as the high/low gain was cool, I simply could not resist the better performance of this tubestage by doing away with that feature.
And speaking of sonics:
Got a little bit more listening in last night, really sounds great so far... not that I expected any less from you, Vinnie, but I feel like the DAC really shines compared to most 'built in' integrated DACs that I've heard.
Oh yeah! LIO's dac was never designed to be a "built-in" dac - it was designed to be an outstanding dac on its own, and one that you could also add in. So if one were to configure a LIO with only the DSD/PCM DAC module, I am very confident that it will easily compete with any dac at that price. And when you add the tubestage, it is a phenomenal dac! :eyebrows: In the future, I'd love to send one out to review as just a LIO "tube dac" - it would be very interesting. When I compare it to my fully modded (Level 3) Sony Z1ES, it is right up there in performance, if not takes the cake (again, with LIO Tubestage added after it). If anyone is going to be at AXPONA, I'd love to demonstrate this so you can hear for yourself.
NONE of the modules of LIO where designed to be "convenience features" that you get with all-in-one products. :nono: They all all my best designs to date, and some (e.g. LIO DSD/PCM dac) I collaborated on with other engineers who designed in an outstanding re-clock circuit, dedicated linear regulated sections on board for every section you can think of. Each dac chip (dual mono) and output stage gets separate regulation, the reclock section gets its own regulation, the XMOS USB input receiver gets it own regulation, etc.
Same idea with the Phonostage, speaker amp, etc. So at very first listen, you should be hearing a big, expansive sound and hopefully one that is seductive and keeps you wanting to listen. That is the true test!
THANK YOU for your post, and please keep us updated as you spend the hours listening and getting familiar with your stealth-black LIO! :notworthy:

All,
Now that LIO pre-orders are starting to ship, I think it will be helpful to start a new thread dedicated to
customer feedback and impressions.
[And as you probably are aware, we also have a LIO "Ideas and Suggestions" thread here:
http://www.audiocircle.com/index.php?topic=130693.0]
I'm just trying to keep the VR forum organized so it will be easier for everyone to find information.
Happy Listening!

I've had my LIO for a couple days now and thought you might like to know my initial impressions. In a word ... S P E C T A C U L A R ! !
The packaging was excellent and everything arrived in perfect condition. Setup was a breze - plug in my speakers, turntable, and a Sonos via TOSLINK and I was ready to go as soon as the pre-charge was complete (less than 15 minutes). I wasn't able to listen much after the initial setup and figured it needed some warm up time anyway, so I set my copy of "Irrational But Efficacious" on repeat so the caps could cycle a few times. Late afternoon, I sat down for some serious listening.
Streaming Deezer from my Sonos sounded better than I expected given the notorious flatness of the Sonos TOSLINK connection (I'll get a decent coaxial cable soon - should be an improvement). I played a few Redbook files from my digital library too and was satisfied that the DAC matched or exceeded my existing gear with the same connection (Sonos TOSLINK to Naim SuperUniti). But I was anxious to try other things and moved on to vinyl.
Spinning some well known records (Mobile Fidelity cut of The Cars first album, Analog Productions version of Bill Evans' 'Waltz for Debbie', Daft Punk's 'Random Access Memories', and my Cisco copy of Steely Dan's 'Aja') I was hit with the immediacy of what the LIO was bringing to the dance. Bass was deep and taught, vocals flowed naturally, and everything had that 'swing' that keeps your foot tapping. Accuracy, extension, timbre, and pitch are all nice (and the LIO has them all), but for me the music is in the pace, rhythm, and timing (PRAT). The performance of the LIO speaks not just of the quality of an individual component like the phono stage, but to the overall design and execution of the entire LIO system. The only drawback? Some of the limits of the Rega Exact 2 cartridge were exposed more than I had previously noticed - so an upgrade there is likely in my future.
Having been sold on the analog performance compared to my existing setup (Naim SuperUniti with Sutherland Ph3D stage), I was anxious to see how the USB connection and high resolution digital sounded like. I got a laptop connected to the USB input of the LIO and the driver installed with minimal fuss. My only qualm would be that the driver should be posted in a .zip format for PC users since it is native to Windows. The .rar file required me to download an unpacking software to extract it - no big deal for a software guy like me, but an extra step nonetheless. But once I had it set up and configured Media Monkey's WASAPI output correctly it worked without a hitch.
Given the positive experience with vinyl playback, I had high expectations for the USB connection and high resolution playback. Those expectations were not merely met, they were exceeded. Easily far superior to the Sonos TOSLINK option for Redbook, the same files played via USB were clearer, more extended, and more energetic. Clearly the USB connection is a superior performer with timing. I eagerly queued up some high resolution files and the room just burst alive with energy and dynamics well beyond any of my previous setups. My KEF LS-50's sang like I've never heard before - not even in a showroom demo. Most DACs smear time, introduce glare and hash with jitter, and just don't sound completely natural, but the LIO DAC nails all these elements like the really expensive components on the market but for a fraction of the cost (and minus the extra boxes and cables). Most files I played were able to swing as well as their vinyl counterparts with all the extension, control, and black background you could imagine from an ultra capacitor AC power free solution.
I'm trying not to get too far ahead of myself as it's only been three days, but right out of the box the LIO is performing well beyond my expectations. I want to thank Vinnie for putting together what is likely to be the best piece of audio equipment I've ever owned. I'll be selling off my old components and now useless cables in the coming days so I can spend the extra money (and time) on music. I couldn't be happier. Keep up the good work.

Hi Tim,
Welcome to the party - and thank you for posting your initial impressions of the LIO! :bowdown: :bowdown: :bowdown:

Good point - and I now have it as a .zip as well for PC users. :wink:
My KEF LS-50's sang like I've never heard before - not even in a showroom demo.
I've heard the LS-50's (and Harbeth P3ESR's) with LIO and they both really shine - and I especially like them for near field listening. Outstanding mini monitors and I'm glad you are finding the same great synergy with them as I did. :singing:

THANK YOU - this is what it is all about! Keep us posted every now and then, and enjoy your LIO!
A couple more LIOs are shipping tomorrow, and more will ship at the end of this week - so hopefully there will be more user impressions
to be added to this thread soon. I really appreciate all your feedback!

Potential firmware bug that's totally trivial, but you may want to note for any future upgrades: upon first turning LIO on after connecting power, with only the DAC module (no analog inputs), you need to cycle through the three A_ sources once before LIO 'realizes' they aren't there. After cycling through A_1-A_3 once and hitting d_1, the list then properly only cycles through d_1-d_3. It remembers through power off/on cycles, just not a fresh start after disconnecting the power supply. Again, completely trivial, but I thought I'd mention it.
…and while we're on the usage subject, it slipped my mind to mention my additional gear above…
Loudspeakers: Audience Clairaudient 'The One' via QED Silver Micro cable
Source: iTunes on Mac Pro 3,1 via USB
…and… well, that's about it, since everything is built into LIO! I also have a Pro-Ject CD Box S that I use as a transport for some backup listening tasks, but I haven't connected it yet.

That would make a difference, wouldn't it?
Mine's RVC, tube stage, DAC, MOSFET amp.
I still have my RWA Sig 16 set up as well, and can say that using LIO just as a tube DAC is quite spectacular as well…
Next upgrade will be the HPA, and down the line a phonostage once I have room for a tt again…

Phonostage
Remote loading
Resistor Volume Control

All,
Srajan / 6moons just received a LIO review unit. There is now a 5-page "preview" starting here:
http://6moons.com/audioreviews2/vinnierossi/1.html (click on the forward arrows at bottom logo of each page
to go to the next page).
While Srajan's review unit is sans Phonostage, I also recently shipped a LIO to John Darko of Digital Audio Review that has
LIO PHONOSTAGE (sans LIO DSD/PCM DAC). Otherwise, they both have LIO HPA, MOSFET AMP, and other modules in common.
Srajan requested both the RVC / TUBESTAGE and AVC modules to do a comparison.
More reviews are in the works - just trying to go in the order of which I received interest from reviewers to be as fair as possible (just like I'm
going through the LIO order queue, and currently shipping about 5 LIOs per week).
I'm looking forward to more customer feedback soon - and THANK YOU in advance for posting! :thumb:

Page 6 is up (http://6moons.com/audioreviews2/vinnierossi/6.html).
Vinnie - I realize the review is not complete yet but I wonder if you could check with Srajan to see about something. I think he did a decent job comparing the sound of the AVC and the RVC-with-tube-buffer. The ending paragraph on p6 is not clear if he has done this yet; but I'm wondering how he might compare the sounds of AVC and RVC with not tube buffer.
So, in the end, we'd have three clearly defined reviews: AVC (no tube of course); RVC (no tube); RVC (with tube).
Very glad to hear the HE-6s shine on the Lio! Anyone want to buy an EF5 headamp, Sig16, Burson DA-160 DAC + a bunch of cables? No one reading the Lio threads! :icon_lol:
Thanks

Hi radarnyc,
Looks like he'll be doing this (according to page 7)! 8)
To suss out its performance, I'd use my €9'000 COS Engineering D1 DAC/pre as the 'bypass' control unit with 256 x 0.25dB step resistor-ladder analog volume. LIO as AVC preamp would then contrast against the D1 in fixed-output mode and my Esoteric C03 transistor linestage. Part 2 would swap in LIO's RVC module. Part 3 would add the tube stage and contrast that against my Nagra Jazz valve preamp.

Hi Vinnie:
Speaking of the 6Moons review, Srajan wrote:
"Where it goes beyond its various precursors is with that single no longer twinned display. It converts to temporary balance mode whenever the remote's left/right arrows are used to lock in up to 12 steps of level offset. Then it reverts to regular volume again which now ramps up and down at the set balance difference."
I always liked the idea of a dual volume display, one for each channel, but understand it's not always practical. Can you a post a photo of the display showing what it looks like in "temporary balance mode"? I would like to get a feel for what it looks like in operation. Thanks!

It looks like ' - ', then '1- ', '2- ' or ' -1' and ' -2' up to 12 in either direction.

Nicely written, Srajan.

Hi Gerry,
I personally am not fond of the dual display for L and R volume. Too complicated looking (just my opinion). John developed firmware
to allow for one display, and using the balance control it allows you to offset the volume up to 12dB (in 1dB steps). Once you do this, as Srajan mentions above, it then goes back to displaying the volume level. But you can adjust it at any time via the remote. Really slick interface! 8)
Just to make it clear, here is an example:
Say you are at volume level 40. When you press the left arrow on the remote, it briefly displays 1-- (meaning the LEFT channel is 1dB louder than the right channel, so it reduces volume on the right channel by 1dB). If you keep pressing the left arrow, it will go like this: 2--, 3--, 4--, all the way until the left channel is 12dB louder. You can do the same thing for the right side via the right arrow on the remote, so it goes like this: --1, --2, --3, ... all the way until the right channel is 12dB louder. From there, you just use volume up and down and it maintains this offset of the volume level.
It is easier on my eyes to see one volume display instead of two different displays at different volume levels. :cyclops:

Of course, I am VERY GRATEFUL for LIO customers posting their impressions here is well. So far, the new VR forum here has a number of informative posts and is really picking up momentum!

I have to chime in here and give you guys credit for LIO's UI, it is really nice. The dual L/R display is very unique and has its own charm, but I must agree with you, it's kind of overboard. LIO has a lot of functionality, and I applaud you folks for cramming all the information into a 3 digit 7-segment display. Something very classy about these 'old' displays, which I fear are going the way of the nixie tube, as more and more devices move over to soulless matrix displays...
The way balance is handled on LIO is clever. Muted state shows as '---' which is far more inviting ('why aren't you using me?') than '0'. You can turn the display off or leave it in freq or v, and it'll still temporarily show level/balance if you change them. It's a very straightforward, no-frills UI, and it's a joy to use!
-
Thanks guys (Srajan, Vinne and BRH)!
I used an early version of the Tortuga LDR-1. It had a similar "balance mode" function as the LIO, with one exception. Forget about a dual volume display - there was NO display! You literally had to count the number of times you were pressing on the left or right volume buttons on the remote to know how much you were changing the balance.
Of course Morten added a display in later versions of the Tortuga units. Given the above, I appreciate having any display of the channel balance setting. Besides, once you dial in the balance, you usually don't have to change it again (unless something else changes).

Hi brh,
Thank you - and I must pass on all the credit of this to John Chapman. In fact, all the credit goes to John for the user interface
and the upcoming Bluetooth control interface (app for Anroid and iOS devices) as well.
And I agree about the 7-segment LED display (instead of the matrix ones). Simple, clean, and you can turn it ON/OFF at anytime. :idea:
Thanks again,

When would someone want to adjust the balance? I'm scratching my head thinking of a reason? Non symmetrical speaker placement?

Hi CarterB,
Yes - that is one reason.
Another is if the room acoustics are not well-balanced and one speaker sounds louder as a result.
Some recording don't have the vocal quite centered, so I admit I tend to fix it with the balance control. For example,
I love Ani Difranco's song "Everest" - but they placed her vocal all the way over to the left speaker. As I adjust the balance
to the right, it is like she is walking across the stage over to the center where I want her to be - step by step. It's fun if you
are an imagining freak like me. :green:

I pretty much can't live without a balance control on my remote. Many songs are off a little left or right and I when I'm listening to random songs from my mac mini I use it all the time.

- Steve Guttenberg of CNET
(and after that, we have others in the line-up: Tone Audio, Headphone Guru, Mono and Stereo, Part Time Audiophile, ...)
So hopefully you will be seeing LIO reviews posted throughout the year - and as I mention above, feedback/impressions
from LIO customers is important and very much appreciated here. Thank you in advance! :notworthy:

Hi Vinnie,
Your such a hard worker and I'm glad that your getting through your orders. It is such an achievement from a smaller audiophile company. I bought my Isabella from you last year and some other products over the years and your customer service is very good.
I'll buy more products from you in the future.

Received my LIO the other day. :hyper: :hyper: Overall, very smooth mid range. Never had it so sweet with LFP-V 70.2 & Isabella, even with Mullard CV2492 in the Isabella which I found works great for my ears. The bass is thinner than the LFP-V but I'm attributing that to the JJ tubes in the LIO, I'll swap those out later. I assume 100 hour requisite break in?
First off my set up:
CD player - Esoteric X-01
Turntable - Rega P7/RB700 tonearm/Exact 2 Cartridge
and to be fair, I need to compare with what I know, my Whest .20 phonostage I've had for about 6 or 7 years now.
DAC - NAD 1050/Schiit Bifrost/ProJect/ a few others (that's why I didn't go for the DAC module, but i think i may do that soon. :duh: and get rid of some of my other ones.
Speakers - DALI Epicon 8, 3 way, 500watt max, 5 ohm (go figure)
LIO configured
RVC/Tubestage, Phonoamp (I have MM cartridge so no remote loading), Mosfet amp.
Some very surface observations. The clicking between ultra capacitor banks is a tad louder than I care for if playing at low volume, you know like when the wife is nearby, you hear it switching over, or when there's a pause in the music and it just coincides with the switch over, but when volume is up loud, no problem. Same with changing volume, again, just something that is noticeable.
When you turn off the amp, and turn it back on again, you're starting at 0. I think it would be great to retain the level where you left off, you know like your TV or Isabella. Once you set a volume you like, and I like it loud, you're there when you fire it up again.
The mosfet amp is rated 64/45/25 and my speakers are behemoths recommended 50watt minimum, (I think I'm getting 40watts) so what a thrill that they actually drive the speakers incredibly well. They of course can't get to the volume I occasionally prefer, and I do have to turn up the volume, to about 35 before I'm getting the level I consider acceptable low. I can crank all the way to 63, and my speakers are singing. Vinnie, stop wincing :nono:, I know it may be a bit too early to push LIO before break in, but hey, I only pushed for a few seconds, had to. As I said, I enjoy music on the louder side. I promise not to do that again till after the requisite break in.
Another observation I will make is that I did enjoy the gain switch on the Isabella, when I really wanted ear splitting volume, boom, there it was. With LIO, I can't quite get there :icon_frown:. Even when I turned off the mosfet and connected the 70.2's to the external var output. The volume really wasn't much different than the mosfet, why would that be? But as for sonic quality, I can say with certainty that the mosfet has it over the 70.2's. On CD, Patti Smith Radio Ethiopia, really old, and Annie Lennox, Nostalgia, really new :?:. The vocal depth on the LIO mosfet is incredible. Cuts right through you. I switched back to LFP-V system, same CD's, I love the sound of both systems, but the LIO has a distinct flavor, more subtle, a bit more laid back, richer, and less harsh, more forward on the mid range. The low end is subtler too, again, I prefer more bass and that can be remedied with tube rolling.
For LP comparison, I played Coltrane Standards and Lee Morgan's Sidewinder, through the phonostage module as well as the Whest .20. The big difference, and it was really significant, was the mid range. Wow, every lick of the reed came through like never before, piano was so upfront yet very musical, really great sound, so I assume after break in it will improve. So there you have it, $600 phonostage module against $2,600 phonostage, plus very expensive cables of course.
And that's the last thing, I have crazy expensive interconnects and power cords, Acoustic Zen, Nordost, Shunyata, that I will eventually unload to pay for this nasty habit. I think I'm having cable separation anxiety. I will keep one pair of interconnects for the separate LIO power amp proposed. Any news on that component yet? (ok, I hear all the low power aficionados rolling their eyes :roll:, I get that, I've experienced low wattage Pass Labs, but for what I'm after in this setup, it's quality plus quantity, I guess I want it all).
Well that's it for now. Great work on the part of the LIO team, the bar is raised, let's see what the future of modular has to offer.

Interesting and good to know.

That's interesting. I had LIO on the desktop, i.e. within half a meter from me. After reading another poster's mention of the bank turnover relay clickinh (and I'd not heard a thing), I set the display to 'volts' to precisely track the switching and pay attention to the relay. Nada. I couldn't hear *anything*. Granted, I didn't turn the music off to see whether I'd hear it then. :duh: And the tunes were playing at quite mellow levels since I don't blast it on the work desk.
With the AVC, I heard no relay clicks either when changing volume but I did with the RVC. Vinnie explained that the AVC relays are quieter. Perhaps whatever controls the ultracap banks can get one of those super-quiet jobs?

I definitely hear the cap bank relays switching in my desktop setting. Easy to ignore? For me, yes… And I think in a full-room setup where one's head isn't mere feet away from the amp, it would be completely trivial for all but the most picky of listeners. But it is definitely there.
When you turn off the amp, and turn it back on again, you're starting at 0. I think it would be great to retain the level where you left off, you know like your TV or Isabella. Once you set a volume you like, and I like it loud, you're there when you fire it up again.
I think this is largely an equipment safety precaution — at any time that volume control could be for the var. line outputs, the power amp, or the headphone amp… I think it resets to zero any chance it gets just to prevent unexpected blasts… Definitely takes a little getting used to, though, coming from a plain ol' pot that stays where you put it. And, balance resets as well, so that's one more thing.
DAC - NAD 1050/Schiit Bifrost/ProJect/ a few others (that's why I didn't go for the DAC module, but i think i may do that soon.
Can't speak to the others, but based on my experiences w/ Bifrost (original), I'm quite certain LIO handily beats it. Just my 2c.

Very cool… I don't have space for a tt setup right now, but I hope to get back in that game soon, and one of the appeals here is being able to pick up the LIO phonostage in the future. Nice to hear your thoughts on it.

just curious , how often is the relay switching? base on clicking sound
-
A few questions: what are the stock tubes in the tube stage now? Can we tube roll now or will that have to wait for an upgraded tube stage? Finally, If we can roll with the current stage, what type and brand of tube would you recommend for increased bass response?
-
The stock tubes are JJs. You can roll away with all of the substitutes listed on Vinnie's site. You just can't change tube family.
I didn't clock the time it takes for one bank of caps to switch to the other and it probably depends on usage (i.e. as headfi amp you'd expect less power draw than fully loaded as DAC, variable gain tube buffer and Mosfet amp). When I watched the 'volts' display on the desktop (that was using LIO in all of its functions except for phono), I'd estimate once every five minutes. It didn't take very long...

I'm not bothered by the sound, it's very minimal, can barely hear it, but it is there on my unit. I wonder if each unit has slight variations based on configuration of modules?

I have used a pair of Mullard CV2492 in my LFP-V Isabella for some time, and today I swapped out the stock JJ's in the LIO with those. Still too soon to say because I've not given the LIO enough time to break in, but the bass is more forward and the highs are a tad more crisp. I will experiment with more tubes later when the unit has had sufficient time to break in.

Hi Catmansound,
Thank you for posting your initial impressions! 8)
The bass is thinner than the LFP-V but I'm attributing that to the JJ tubes in the LIO, I'll swap those out later. I assume 100 hour requisite break in?
I do recommend 100 hours of burn-in before swapping tubes, and this way you'll get familiar with the sound with your LIO / stock JJ tubes. You'll also want to put on at least 100 hours before critically evaluating, as I always recommend.
Compared to all the RWA products, the I find the LIO's bass is the tightest and most accurate. Part of that has to do with the high current output stage (2-ohm stable), and the other part of that is the ultracapacitor power supply (very low output impedance).
When you turn off the amp, and turn it back on again, you're starting at 0. I think it would be great to retain the level where you left off, you know like your TV or Isabella. Once you set a volume you like, and I like it loud, you're there when you fire it up again.

brh is correct! Since LIO serves as many functions (multiple inputs from dac, phono, line-level in) and multiple outputs (speaker, headphone, preamp out, fixed out), John and I wanted to mute when turning ON and when switching sources / outputs so the user can set the volume and there would not be any accidental blasts, pops, and the like. For example, if you are using a low output MC cartridge and/or headphones that need a lot of gain, you'll probably have the volume closer to max. But if you were to switch to the dac, and are then are feeding efficient speakers, you could forget to lower the volume when you make the switch... and that could be trouble! :icon_surprised:

Hi alamakazam,
Depending on the load (how loud you play speakers, how many modules are configured, etc) the switching happens approx. every 5 to 10 minutes.
The UCAP bank switching is done by a power relay, as opposed to a smaller signal relay used by the RVC and AVC modules. If you are close to your LIO and your music is playing very low, or not playing at all, you will mostly likely notice it (and as others have pointed out, it's not bothersome). Otherwise, you probably will not notice it at all.
If you had the top open when playing your LIO, you would notice the click more.
I can look into a peel-n-stick sound deadening material for the relay (e.g. dynamat) that probably will attenuate the click, but I'm not sure if it really is necessary. :?
Can't speak to the others, but based on my experiences w/ Bifrost (original), I'm quite certain LIO handily beats it. Just my 2c.
The LIO DSD/PCM dac module is seriously good, and I'm hoping people view it as a 'no-brainer' once they hear it. As I mentioned before, when I use it (followed by LIO Tubestage), it is at the same level or possibly slightly better than my Level 3 modded Sony Z1ES.
It is a big jump in performance for any dac we've done in the past! If you don't agree 100%, please return it for a full refund. You can't lose! And the same goes for LIO PHONOSTAGE. It punches well above/beyond what it's price may have you believe! :eyebrows:

Haha - you just couldn't help yourself! :thumb:
Have fun, and thanks for all your posts!

Vinnie,
(a) Couldn't the Balance setting be retained? Although you mention liking to personally adjust balance per song, I would assume the majority of people might be using it to offset the more permanent aspects of speaker placement and room acoustics.
(b) How complex (if at all possible with current control circuitry) would it be to have the last volume retained for each input? That could satisfy everybody and all input level scenarios.
Steve
Hi Steve,
a) There should be a way to retain the balance setting. I will check with John on that one.
b) I'll check with John on that as well.
What are you are looking for is all in the firmware (John's department) and should be doable, but let me
check in with him.

I really like the idea of retaining volume level for each input, my Audi does that, phone, iPod, etc. each retains the last setting you left it at so when you switch back, the volume is where you're expect.

Cool - this is something that we should be able to do, but give us a little time...
Thanks for your suggestions!

Some feedback posted on headfi.com from the SoCal CanJam show a few weeks ago:
http://www.head-fi.org/t/742354/vinnie-rossi-lio-ultracapacitor-powered-modular-hi-fi-system-is-here/75#post_11509974 (http://www.head-fi.org/t/742354/vinnie-rossi-lio-ultracapacitor-powered-modular-hi-fi-system-is-here/75#post_11509974)
In a previous post I talked about the LIO. I was really impressed with the unit and am looking to try one out in my main system. The HE-560 off the speaker taps was quite good, but even from the hp out it sang. The modular design and isolation from the AC mains makes the LIO very tempting.
One vendor I failed to mention was Vinnie Rossi's LIO. I've owned at least 5 of Vinnie's components over the years, mostly for a long-gone speaker system and have always been a fan.His new LIO modular, ultracapacitor stacked audio system was very impressive with the HE-560 it was paired with. There was the usual solid palpable body to the images, but what I noticed the most was the impressive bass, and soundstaging that far exceeded that of the Isabellina HPA, which I owned a couple of years ago. I couldn't evaluate the black background benefits the ultracapacitors bring to the table over batteries due to noisy show conditions. Unfortunately I couldn't audition my LCD-3Cs on this because I didn't have the balanced adaptor for my cable. This is also a system I would like to explore further since it has the ability to push ~45W (if I remember correctly) into speakers and it will be one to consider for a dual Headphone/Speaker system. It was also great to meet the man himself and his lovely wife.
Vinnie was there to help showcase the ALO CDM, since he helped design it. He also brought his new LIO ultracapacitor-based modular system. I listened to the HE560 (I think?) he had hooked up to it, and this amp is a beast! It simply manhandled those cans. So much life and PRAT to the music. Yet so perfectly pure and clear. I was really blown away…I only wish I had a quiet environment to have experienced it. I’m curious if others had a chance to hear the LIO and what they thought, as to me it sounded way better than a lot of the much hyped amp/dac gear I had read so much about.
Steve Guttenberg (The Audiophiliac / CNET) also recently posted this on his facebook page. He is in the process of reviewing a fully-loaded LIO with tubestage:
The Vinnie Rossi LIO integrated amp's balanced headphone amp is a thing of wonder. It's super transparent, and still has oodles of soul.
Thanks again for all your feedback, posts, questions, etc. Keep 'em coming! :thumb:

Please mind my English as it is not my mother language
I owe a pair of brand new B&W 800 Diamond which replaced my B&W 800 signature and the speakers are driving by GOLDMUND power and pre amps (over 10 years) with Redwine Isabella HPA as a DAC. The system sound is satisfactory however the weakness is the low bass.
I believe it is the right time to upgrade my DAC, I like Tube therefore I went to Redwine website and realized the products has now been replaced by LIO. Since it is now can play DSD and 32/384 file, with no doubt I immediately ordered a Deluxe version.
Two weeks ago it got delivered to my place in Australia and I had few days listening to its DAC part, the sound is astonishing which is well outperform my HPA even my Mytek 192, actually I believe they are really different levels.
Second stage, I connected my HD650 and have a listen, frankly speaking this is the first time I agreed that HD650 is a really good headphones , the sound quality is much better with LIO instead of Sennheiser's HDVA 800.
Yesterday, I tried the LIO's MOSFET amp and wondered whether it could drive my B&W 800 Diamond. After two hours listening to the system I would like to use one sentence to conclude "why I bother to revert back to my GOLDMUND amp system"

It sounds like LIO is really working out for you with your speaker and headphones - glad to hear this! :thumb:
Enjoy your listening, and thanks again!

Sounds right! Every module has thoroughly impressed me on its own merits so far… Mashing them all into an 'integrated' still boggles my mind…
