Unbelievable tease! :evil:
Is it flat?
If it replaces the MiniBUSS, and is close to the same price, I may buy it for my upcoming trip to Taiwan. Otherwise I'll take the MiniBUSS as we've discussed. My flight leaves in 6 weeks.

Go, Dave, GO :green:
-
That's an awfully big carrot your dangling in front of us... :D
-
Is it bigger than a bread box?
Animal, vegetable, or mineral?
-
Just when I was about to write you about making me 3-4 power cables, you post this... Sigh.
-
I bet this is Dave and Triode Pete's joint project. I just hope I can afford it.
-
What "things" might it change?
-
Well, knowing Dave, Who the hell knows...... :) I don't even care. How's that! lol Just look at all we got to go on. A huge thumbs up with a shit eat'n grin. Unless of course, he is talking about his health/wellbeing . Then I'll care.............................. a lil bit. ;)

We could all pool our money together; buy the new item, and have it sent to my house for the break-in period. It's a sacrifice on my part, but I accept it as a duty to help everyone out. :thumb:

It won't be a very big pool, so feel free to do so. :thumb:
One of the products coming is the DigiBUSS. It will be the first of my products that uses a very high current (R = < .002 ohms) common mode inductor to address rampant problems that accompany all of the digital junk in our lives/systems/homes. It is a very specific product to mitigate the RFI and EMI rampant in our homes... especially smart homes.
The Digi will be another ugly little black box meant to hide in the background and not make a big, expensive visual statement. The Audible Difference will be that guy. :D Dimensions are being finalized, but it is essentially the size of a MiniBUSS and the standard unit will have 3 P&S 5362A receptacles that are individually split into 6 discreet outlets, each with their own RC networks. Low pass knee on this device will be ~ 100Hz with modified 2nd order attenuation to kill the junk running around in our personal grids. The DigiBUSS is bi-directional and will prevent back-feeding digital hash from the system as well as prevent it from entering the system.
I have searched a long time for the right inductor to do this that will do less inductive harm than is absolutely necessary in a passive application. In my system it is essentially transparent in the context of current limiting to an UberBUSS driving what I have in my lab system. It will be up to you guys to give me feedback on this product in the context of SQ. Your systems are your systems and you know them well.
Target uses are:
power all of those pesky SMPS that feed gear like the Regen
feeding home computers
feeding the system in general
digital sources
front end to an Uber or Mini
anything else you all can come up with to make overall SQ better
I am in process of obtaining parts for an initial run of ten Digis. Hopefully end of next week I will have everything I need. Right now my supplier is out of the Furutech IEC power entries in gold. I have more than enough in rhodium. Initial pricing is still TBD but will be in the $350 - $375-ish range. There will be a reduced price on the first 10, but that will be forthcoming in the next day or three.
The BUSS-Stop is being discontinued. I will honor any (if ever) warranty issues. No problem.
I recommend the ZenWave modified Surge-X for any local surge protection you need. I am still a proponent of whole house protection, but the Surge-X as modified by another Dave is the best device I know of to handle this task. :thumb: My advice? Use them both if you are really worried. We live in Albuquerque NM and the thunderstorms can be fierce.
The next product coming is an 80 amp/600VAC capable DC hum eliminator. Still in final development. I will be sending one to Triode Pete in the near future for vetting. As far as I can tell it has zero audible impact on incoming AC. Cool, huh. 8) Again: Price TBD

Dave, have sent my order.....anxious to put this in my system.

Nice Dave!
Would this device be an answer to some who have noted their digital sources lose some dynamics when plugged into an Uber? My dac definitely sounds better through the Uber at this point.
If one has a Busstop( Is it too early to call it vintage? 8)) and an Uber would this be plugged into the Busstop only or could it be daisy chained to the Uber?
-
Dave,
Put me down for one and the power cables I sent you a PM on. How do I do that officially.

Problem with some digital sources is that their SMPS do not take too kindly to a capacitive input. For example: my Mac mini sounds better plugged directly into the wall for AC input... at least until it met the DigiBUSS. IME, most small SMPS respond much better to input polarity proper inductive loads than a capacitive load like the Uber. It is all about input impedance matching.
What digital source are you running?

Thanks, Shawn. I'll get back to you on the cables. This last week has been a blur of physicians. Weird getting old-ish. :?

What digital source are you running?
Auralic Aries with the femtoclocks and upgraded power supply going to a Lampizator L4. 've gone back and forth between the Stop and Uber with Aries and have it currently in the Stop. Not sure why other than that's just where I left it last.

Cool. The Stop is a product I am proud of. Even so, it is best to admit when another AC-er has a better solution for some. Pete was and is one. Dave at ZenWave is another. Facts are facts. As with Pete's cable, some of my cables are frankly better than his in specific applications, but his meet a wider audience than mine. Same with the ZenWave Surge-X. Dave (the other) has gone to great lengths to POOGE that commercial piece.
POOGE = Progressive Optimization Of Otherwise Generic Equipment. He dun gud.

The impedance will be higher with a CMC inline the SMPS's operating frequency. But that doesn't mean your benefit isn't from a greatly reduced amount of common mode noise that SMPS's itty bitty transformers can crank out.
Dave, I understand if you don't want to answer but I've got to ask, a 2nd order crossover (traditional) would have 1100uf~... that's too much for line, so?
-

Pretty sure that's in Webster's... :D
Have you compared the Busstop side by side to the Surgex by ZenWave as far as listening impressions go? Or are you alluding to the surge protection the Surgex offers. I like the Stop because I can hide it behind the rack.
-
Nice to see you back in the saddle, Dave. :thumb:
I can't wait to find out what's new.
Have fun,

Hope you can work that out Dave.

Would there be any benefit from plugging an LPS into this new unit over the Uber? I have an LPS that runs my MacMini and my Phono Pre. Currently it is plugged into the uber.

It will work better in conjunction with an Uber, but will be a great stand alone addition to most systems.
Its' strongest application is to prevent interference from being back fed into the surrounding devices. It began as a filter to keep all of the noise from my office computer system and all of the USB chargers that live in the office out of our electrical system.
[ I wince every time I see one of the new electrical receptacles with an onboard USB charger. What everyone needs: the cheapest (noisiest) USB little radio station and EMI generator possible]
One of my acquaintances told me about he was going to have one of these always on pieces-o-crap installed in every room of his house. :duh:
All of my products are meant to be adjuncts to each other.
FWIW, of all of the things that I love about my mini - its' self noise ain't one of 'em.

Dave,
Looks very interesting for the PC Music Servers as well with the brick SMPS.

So?

So?
Great record by Peter Gabriel :thumb:
I'm still waiting on a quote. I'll post as soon as I know.
:sad:

Dave,
If you still have room in your initial 10, count me in on the DigiBuss (as well as your DC hum eliminator when you get to that). Can't believe I missed this thread earlier when you first posted it. I'll PM this as well.
Thanks!
Mike

Looks like the final cost will be $349.00. The initial run of ten will be $299.00. Wait a few days until I am sure. :)
-
So as I understand this (and when I get one (heh)). I plug this into the uber and then plug all the wall warts into it? Better to plug it into the wall and then the uber into it? Would the LPS benefit from being plugged into the uber or this?

As always I advise to try every configuration to get the best sound from YOUR system, but the design intention is for digital gear to be plugged directly into the DigiBUSS. This will keep backfed digital hash out of the rest of the system.
-
So could a DigiBuss be integrated into an UberBuss for application-optimized outlets? Digital / pre-amp (/phono pre-amp) and power-amp (/ integrated amp) optimized outlets?

It would require a much bigger enclosure. The Uber is FULL! With infinite time and unlimited money anything can be done! :lol: :lol:
Seriously, now: sure. I'll have to figure out the ultimate size of the inductor module squeezed down to fit. Can do.
-
Realistically, I have things all over my house that could be injecting digital hash into my electrical lines. Would an ultimate solution be to use a DigiBuss on every computer, laptop, router, game console, TV, DAC, etc... in the home? Would that be likely to afford a significantly greater sonic improvement than just using one for the digital components on my main audio rig?
Seems like it would be an interesting experiment to find those digital sources that are contributing the most hash. Is there a way to find those worst culprits other than just by moving a DigiBuss around and listening?
-
An interesting experiment might be use an AM radio tuned between stations and put it near the noise sources. Without moving the volume control see which ones make the most noise from the radio.
The frequency range you can check is 530KHz to 1600KHz with the dial. A HAM radio might be better for a wider range. Most SMPS will probably have HF noise in that range.

What I did was to move everything that I possibly could into my Lab/office. All of the phone SMPS, camera battery chargers, iPad /Kindle charges, router, AirPort Extreme and every other small SMPS etc, are in here. Those and my Mac are plugged into a MiniBUSS and prototype DigiBUSS. Makes a big difference. Attacking a problem at the source is the best way to fight that problem. That is something that many have not yet figured out in audio and other issues.
I have issued a moratorium on electrical receptacles with integral USB outputs. :green:

My old Sunfire amp was such a noise generator that it would cause hash on the TV. Doing what you suggest will also show just how noisy some linear supplies are, too.
Noise - our enemy.

Hi Dave, are these units worse that the usb chargers that you would plug into an outlet? I have one of the integrated units.
Best,
Ed

I don't see how they can be any better. The lowest possible cost mini-SMPS directly connected to the circuit with any mitigating effect of the inductance/capacitance in the cable to an outboard SMPS. I guess I need to measure the spectra, but I have way too many irons in the fire to go buy something I would hit with a hammer. :) Putting an old Noise Harvester or something like that on it would help, methinks.
-
Great idea, Dave, to centralize as many of these noise makers as we can into a single location. Can't cover everything but it'll help me thinks. Still, I'm gonna need a few of these DigiBusses if they really improve things sonically.
I often wondered if those PS Audio Noise Harvesters actually worked or if they were just pretty doodads that made you feel better when the light flickered.

OK, everything that I need to build the DigiBUSS has landed here and I will begin the initial run next week.
Please send me a PM for payment instructions and they will go out in the order that payment is received.
Everyone have a great weekend. :thumb:

Dave,
If you recall, I'm fixin' to fly back to Taiwan for a spell. Nearly all of my audio equipment is going into storage a few days before we hop on the plane. I'm starting with all new equipment over there. My amp will be a Nuprime IDA-8 (100W class A and D integrated with built in DAC), SqueezeBox Touch, Mac Mini, and monitor speakers.
My 'flat/condo' is in a 12 story building.
Until you announced this new product, I'd planned to order a MiniBUSS. Now I'm confused just enough to need to ask you: "Which single unit is more appropriate for my situation?"

Given what you have, I would say the DigiBUSS is the best choice.
-
In that case, put me down for one DigiBUSS!
I'll PM you my Taiwan address. I won't be there until September 15th, so no point in sending it too early.
Be sure you slap on a label, tag, or plate that says something like "Proudly made by P.I Audio in the USA" (or similar). I'm sure a little advertising or extra name recognition won't hurt. :thumb:

Be sure to add a few business cards inside the shipping box...just in case I happen to get friendly with the independent Brick & Mortar shops near my home in Taiwan (3 stores that I know of).

Ill try to send you some. I haven't had any for a couple of year because I have had as much business as I can stand.
Thanks, Mike!

First run + 1 is full.
Price hereafter is $349.00. Subsequent units AE about 3 weeks out. This old man can only work so fast :(
Thank you everyone. Production begins this coming week. :thumb:
-
Update:
Receptacles (I order in lots of 100, so it takes a while... ) are in and everything hits cryo tomorrow. This is a 3 day process. I am working on other orders and will get to the cryo parts and pieces this weekend. I will do sorting and qualifying on the components over the weekend and will begin building enclosures next week.
On of the great things about my business is that I always have items in the production queue. One of the things that sucks about my business is that I always have thing in the production queue. Blessed and cursed at the same time.
Thanks, guys for being the best clients EVER!
I love my job. :D

Hooray!
By any chance, does that cryogenic have Fridgidaire or Amana emblazoned across the front? :icon_twisted:
Sorry. After watching the stock market plunge recently, I need to throw out a little humor. :o
I'm really looking forward to this.
