Insight DAC -- First Review
« on: 18 Jul 2008, 03:07 am »
The Insight DAC was waiting for me when I got home from work yesterday.  And while I was eager to take it out, hook it up, and start throwing my music collection at it--I had to get my kids to bed.  That was a hard few hours...  I'll just post a few of reactions and reflections of the product for those who may be interested.

My first impression was to appreciate the packing and attention to detail.  The packing is well designed and engineered, and the DAC made it to my doorstep without incident. 

It was then that I realized that I should have asked Frank to sign the faceplate.  (Kind of like the Carver Signature Series.  How cool would have that been?  For a second, I contemplated sending it back w/ this special request.  Yeah--only for a second.) 

My first reaction to the DAC itself was to realize that AVA gear has had a chassis upgrade relative to my models.  Don't get me wrong--my (older) chassis are perfectly fine--and I think, attractive.  However, the new chassis line seems to be a bit beefier--but not overdone.  A subtle change and subtle improvement, I think.  The finish on the hood seems different from the older gear--and I liked it.

Now--for a bit of background.  I'm an asst. professor of speech science, which makes me both empirical and cynical.  I find the audio industry quite hysterical for it's snake oil, pseudosciene, and marketing based principles such as "cognitive dissonance" and the insecurity / ignorance of the buyers.  I sold mid-fi while in college, which gave me an over-exposure to the mid- in mid-fi.  So after my shifts were over, I'd head over to the higher-end salons to listen and learn what I could.  (As well as secretly scoff at the magical mystery products.)

Finally--I follow the Dave Ramsey perspective to personal and family finance.  No debt, live beneath your means, increase one's security through savings.  As a result, my system may be meager compared to others--but I'm quite satisfied w/ it, and it fits within my fiscal and family values.  I'm using a pair of Acoustat 2+2 (electrostatic) speakers.  Their positioned fairly well--but not *perfectly* optimal.  When there's the combination of high voltage and a 2 year old child, one makes compromises; as a result, they're currently behind baby-gates.  I'm driving them w/ Frank's SS gear; the 440HC and the SL pre-amp.  (Older, smaller chassis.)  My source was actually an Alpine DVA-9860 DVD player.  It's got a pretty darn sensitive tuner, and the specs on the DVD player look good on paper at least.  And it's quite convenient to put an artist's library (or multiple albums) on a single DVD.  The Alpine uses TosLink--so after consulting w/ Frank, I just went to Walmart and picked up a Phillips DVD player w/ coax digital out (and w/ USB input).  (I hope to get an external hard drive and just put my library on that.  Hopefully, the unit will play uncompressed (.aiff?) format from USB.)  Speaker wire is just run of the mill Parts Express brand 12 gauge; interconnects Monster 401 w/ PartsExpress connectors.  (They had a deal-of-the-day about 11 years ago; 50 feet for like 30 bucks.  I've probably still got about 30 feet...)

I didn't know what to expect, so I was pretty excited to listen for a difference...

My initial (and immediate) impression is that the Insight DAC had more "punch" than I was used to.  (I guess others might call this "bass attack".)  Then my analytical side kicked in and thought that the Insight was probably louder than my other source, and this was a trick of psychoacoustics.  So to test this theory, I did some AB w/ the Alpine--and realized that the Alpine was a good decibel or so *louder* than the Insight DAC.  (i.e., The Insight's "punch" was present in a softer overall volume.)  This difference was easily noticeable with even a minimal amount of attention.  I'm pretty confident I could consistently identify it in a blind AB test. 

My next impression is hard to describe.  "More."  Or maybe better described as "More Complete."  Again--difficult to express.  "More Natural" may also be a good way of describing it.  My personal benchmarks for critical listening include: (1) the male voice; (2) a piano; (3) an acoustic guitar.  So while playing a male vocalist, even my wife (a disinterested party, albeit with a good ear--she played in the symphony for a major metropolitan area as early as High School) commented that the vocalist was more "natural sounding" than before.  I'm not exactly sure what or why this would be--other than to suggest that the harmonic structure is better intact.  And or what it's worth, this phenomenon remained consistent across the board--such as in acoustic guitar, piano, violin, etc... 

I kept on listening after the wife and kids were in bed--probably a little too late to be honest.  What can I say?--it was just a lot of fun to throw any number of CDs at it.  Time seemed to fly by.

Another interesting observation is that the Insight DAC seemed to make my crappily recorded / engineered discs sound better than before.  More tolerable / less annoying.  I haven't a clue why this is the case, but I'm exceedingly confident that it is indeed the case.  If anyone can explain this to me--I'd love to know why. 

So once I settled down for a bit, I did begin to pick up new details that I hadn't heard before.  Subtle--yes.  But definitely present with even minimal directed attention. 

I'd like to end this by complimenting Frank on his engineering, and for producing (yet another) excellent product.  I'd also like to thank him for his generosity and his profound taste in product names.   :D  I probably never would have shelled out the money for a DAC due to my fiscal and family values--but now that I'm listening to one, I can certainly vouch for its merits.  I can also see product upgrades in my future, albeit after tenure.

I certainly wouldn't suggest starting off a system w/ a DAC; that just wouldn't make sense at all.  But once you've got a good set of well-positioned speakers, with a good amp and pre-amp... along with well recorded and engineered CDs, I can definitely see how a DAC (specifically, an Insight DAC) is an asset to your system.  No doubt about it, in my experience.

I plan on listening to the Insight DAC exclusively in the coming weeks, and then switch back to the old source to see what I notice.  If there's any interest, I'll post my experience.

In short--it's made my music collection more interesting.  This, in turn, makes life more interesting.  Well done, Mr. Van Alstine.

Great review...thank you! You lucky devil.  :icon_twisted:


I wonder if this uses the newer DAC chip that Frank mentioned was going to be used for the differential DAC...and if so, does it further change the topology at all.  :scratch:

Thanks for the review.  I notice an improvement the most after I've become used to it, then take it away.  Please let us know what you hear when you experiment and remove your new DAC from your system in the future.

By the way, you might try an experiment with different speaker wire.  I like what I'm hearing with ptfe-insultated (teflon) silver plated copper wire.  I'd like to try 18 ga. solid, I like 20ga. solid, and 16 might be the choice for classical music.  The price is right.

Thanks for the thoughtful review and kind comments.

I am pleased that the Insight DAC came through so well even with our earlier solid state equipment after it.  I had not tried that combination here yet, having too much fun with the complete Insight system and mixing and matching with the Ultra equipment.

We did the Insight preamp circuits first, then the DAC, and finally the power amplifiers using our best Ultra hybrid equipment in the rest of the chain in each case.  The WOW factor was huge with each step.

By the way, some of the new ideas also are applicable with the Ultra and T8 DACs, as each need a solid state current to voltage amplifier section on the digital board before the tubes can take over.  These have been made as running improvements to those products as of July 1st.

Regards,

Frank Van Alstine

P.S.  The digital stuff in all our production DACs remain the good old Philips 16-bit stuff.  There seems to be a lot more life in this technology than we had ever anticipated.

Thanks, very 'Insight'ful review.  :wink: 

Please do keep us posted on the future a/b experience. Good life philosophy as well.

gjs_cds,
Fine review.  Nice speakers, too.  Heard a restored double pair at the AudioKarma show last year driven by Frank's Ultra Pre and Power Amps.  I thought they were "best in show".

Frank: Have you priced the upgrades for the Ultra yet?

Insight upgrades to OmegaStar product pricing is not available yet.

We will let you know when the new boards are finished and tested (in about 3 weeks)

I guess this means the ideas applicable to Ultra have not yet been tried, let alone being ready for upgrade.

Some of the ideas are appropriate to the Ultra DAC and T8 DAC and these have gone into production as running changes as of July 1.

The new concepts are not applicable to the tube or hybrid gain stages in the T8 and Ultra preamps.  They are doing just fine without them.  :)

Frank,

Could you provide a brief summary of the sonic charcateristics of the new Insight DAC vs. those of the Ultra and the all-tube DACs?

Also, I may have missed it somewhere in this circle, but what is the price of the new all-tube DAC and of the Insight?

Thanks.

Now what are the customers supposed to do with their older version (some just bought it a few months ago) of the Ultra and T8 DAC????? I thought AVA product wouldn't go down the path of being obsolete.

Another round of upgrade?

Interesting anecdotal finding regarding the Insight DAC.  Our system is literally on from 6:30 am till after 8:30 pm; the entire family is very big into music.

We've got all kinds of kid's music for our daughters--and tonight I was in for quite a surprise when I played "This Old Man".  I popped it in, and instantly thought--Dang, 'This Old Man's' got some bump.  I'm attributing it to the "punch" or "bass attack" previously mentioned in my review.

The effect was most noticeable.  Not even close to subtle.  Who thinks to give focused attention to kid's music? 

Yeah--my kids are sonically spoiled rotten...

Finally--it's really interesting in that I'm growing more accustom to the Insight DAC sound.  As a result, I still find myself picking up new sonic characteristics even after a couple days use.  This is one great product!    :D

How to be sure of avoiding dealing with a company that is always researching how to build better audio products, is never satisfied with the status quo, and from time to time announces better performing products:

Its really easy.

Buy the last product offered by a company that is closing its doors and going out of business.

Frank is allways working to make things better, when I got my 550EXR every one was talking about the EXR-5 upgrade and what do you know, my 550 was a 550EXR6. Always working to make things better. Some upgrades are bigger then others some you never hear about. For new buyers think of what you are getting, I keeping sticking it to Martyo, my 550EXR6 $2,200 his Ultra 550 $2,200 my T-R DAC $1,600 his Ultra DAC $1,600 my T-5SLR $800 his T-8 $1,200 with new box and 6N1P tube sounds like a good deal to me. Frank's new stuff sounds better then mine but I am more then happy with mine, some time down the road I may go for an upgrade. :smoke:

Hey Charlie, the Ultra DAC just got upgraded too, and remains our top of the line product.  No increase in price - - -  yet.  No need to wait.  :)

Insight Upgrade Prices
« Reply #17 on: 21 Jul 2008, 08:28 pm »
OK  Upgrade prices (preliminary and subject to change - very likely upward).  Insight upgrade to basic OmegaStar DACs, preamps, control amp, and power amps: $300.00 plus shipping, including a new three year parts and labor warranty.  Insight upgrade to preamp optional circuits such as phono, tape buffers, or inverters; $150.00 per option.

Upgrades to older AVA solid state equipment will usually be possible, but price will be determined on an individual case basis.

Special deal for our "but I just got the now obsolete unit" customers.  Insight upgrade is half price for any OmegaStar units shipped since April 1, 2008.

Best Regards,

Frank Van Alstine

Hi Frank, When you say older AVA does that mean you can put the new stuff in a PAT-5? :smoke:

A quick update on my experiences with the Insight DAC...

Being such an empiricist, I find myself trying to quantify the changes that I continue to pick up on a daily basis.  The thing is--I can't seem to put my finger on it; these changes seem to be dynamic relative to the source (i.e., CD).  I will say that the Insight DAC has made music more interesting though...  Playing a CD often results in that "first time" experience--because I find myself (now more than before) picking out new details in the music.  And the more "in-tune" I get w/ the Insight DAC, the easier it is for me to pick these (new) details up.  (Now if I could just quantify it!)

More dynamics, definitely.  Call it "punch" or "bass attack"--but the effect is most definitely there.  This increase in dynamics seems to make the meat-market music-CDs (i.e., overly compressed recordings) a little more interesting and increasingly tolerable.  On better recordings, I'm finding increased realism in percussion--cymbals especially.

It's a great product--no doubt about it.

As an aside, I finally realized that the Insight DAC reads the PCM digital format.  I have my library recorded on my home computer network in a lossless format--and I thought that I couldn't feed this library through the Insight.  I can.  My Phillips DVD transport can be set to a PCM digital output.  Further, Mac computers and the Apple AirPort Express also pumps out PCM (although an optical to coax converter is required.)  Point being--the Insight DAC is easily integrated into modern digital media libraries.

Great work, Frank.  Your products make life more interesting...
