1 week from tomorrow I will be doing a DAC shoot out with a Hugo Chord, Wyred 4 Sound DAC-2 DSDse with Femto Clock upgrade, Bryston BDA-1, the New Exogal Comet and an IFI (the IFI is just for kicks).

Products

I live in the Twin Cities and saw that some guys from Wadia broke away and started Exogal here in the TC's. So I gave them a call and they are going to loan me a Comet for the shoot out and in return I will write a review on a few forums. It should be fun. I will put the Comet through the paces in my system for a few days, then take it over to a friends house for the shoot out.

More coming in a week.

Cool. I own the chord Hugo. Awesomeness - great piece of kit and easy to take with as headamp and DAC.
 
The W4S is the more evolved product. The Comet spec page shows nothing of substance except inputs and outputs.

You may be right but spec's aren't every thing. My Parasound A21 amp has way better spec's than my Pass X250 and the two amps are not even close in sound quality and enjoyment with the Pass being the much better of the two amps.

I have heard the W4S and Hugo head to head in my system and both are excellent and have their strong points. The W4S has razor sharp detail and resolution with great bass, dynamic's, attack and neutrality. While the Hugo has a more romantic, warmer, richer and smoother sound with a midrange to die for.
 
Not saying one sounds better than the other based on specs only that the Comet spec page shows nothing about the makeup of the unit itself. Looks like what you would see on MD. It may in fact sound excellent they just provide you nothing to work with accept ad copy.
 
The really unique technology that the Exogal Comet offers is the custom software they developed to implement its 'spline' filter. It's an updated version of the filter that the same design team originally used in Wadia's top decoding computers (DACs), which claims to maintain better phase coherency than other more commonly used filter types. I also understand that the optional upgraded external power supply ($500) makes a significant improvement in the unit's performance, so hopefully they are sending you that as well. Looking forward to your evaluation from the shootout!
 
Here is a recent review of the Exogal Comet: Exogal Comet DAC | AudioStream

Received Michael Lavorgna's AudioStream Greatest Bits award...some photos taken from the AudioStream review:

I received the Comet about 45 min ago along with the external power supply upgrade. My initial impressions are that it is well built. The sound is very good. It has a completely black background, it is very transparent with good detail. It has a very smooth or liquid sound and does not sound digital using my Music Hall 25.2 CD player as a transport through optical cable. Right now I have it hooked up using single ended IC's, I will try XLR tonight.

Thanks sounds very interesting. I do like smooth sounding dacs.
 
I have been listening to the Comet for at least 3 hours now and I have a better impression of it.

When I first listened to the Comet I was not initially wowed like I was when my friend brought over his W4S DAC-2 DSDse and Chord Hugo a few weeks ago. I thought this sounds very good but I was not hit with the immediate feeling that this was a piece of Kit that I needed to have. But after listening for a good while I found myself smiling for no reason and really enjoying the music, more so than I had in a long time. I had to sit and think about why and then I started thinking about what was missing from the sound. There was no glare, digital edge or fatigue and no sibilants. The back ground was completely black. I found the sound was very easy to listen too leaning on the relaxed side as I began to think about what was right with it. It is very liquid, holographic and 3D with fantastic transparency. The sound stage is wide and very tall. Bass is tight, well controlled and pleasing although it could use a just a little more weight with my Maggies. Cymbals sounded perfect and not too forward or pushed back. Vocals and horns are to die for, very natural and smooth. Drums had good kick to them. There was good spacing between instruments. Overall the sound is very analog and neutral with maybe a hint of warmth. The dynamics are good but not on the level of the W4S DAC-2 DSDse which has great slam, and there is good musicality but not to the level of the Hugo Chord which I really like but seems to sugar coat a little like the old CJ tube gear. I think that is why I was not initially wowed by the Comet, but the more I listened, the more it won me over as I realized that the sound is excellent and it just sounds right. It is a very analog sounding DAC and I just might buy this DAC after I hear a few more at Axpona. I really would like to hear a Marantz Na 11s1 and a lower level Lampizator as my budget is around $3K new or used.

More to come on Sunday after the DAC shoot out.
 
Larry - Thanks for sharing such detailed initial impressions of the Comet, it sounds very promising! Try to enjoy the shootout and I look forward to reading more about your findings.
 
Here is the review-

I am going to upgrade my DAC some time in the next few months and I have some friends that have a Hugo Chord, Wyred 4 Sound DAC-2 DSDse with the Femto Clock upgrade and a Bryston BDA-1 DAC. We decided to to a DAC shoot out and compare them. Then one of my friends sent me a link to a new company called Exogal based here in the Twin Cities. They have a new outstanding DAC called the Comet which sells for $2,500 and $3,000 with a beefier external power supply. So I emailed them and asked if they would be interested in including the Comet in the shoot out. Jeff the CEO was game and dropped the unit off at my house about a week before the shoot out. I had a few days to play with it and was very impressed with the sound. It clearly bested my aging AVA Ultra DAC a hybrid tube design. I will go more into how it sounded in my system after the shoot out results.

This past Saturday night 2 friends and I went over to another AC members house for the shoot out. For kick's one guys brought over his $500 IFI DAC and $299 IFI tube buffer to see how it would stack up against the other 4 dacs.

Equipment used-

Magnepan 3.7 speakers
Dual AVA HiFi 600R amps used in a mono block configuration at 600wpc @ 4ohms
AVA FET CF tube Preamp
Computer based music using JRiver software
Emperical Audio OR5 off ramp USB converter which allowed us to immediately switch back and forth between 2 DAC's at a time.

Because we could only switch between 2 DAC's at a time we compared each DAC to each other, picking out the one we thought sounded the best and then compared the 2 winners. Here are the results-

The IFI was clearly out classed by the other DAC's in detail, resolution, dynamics and listenability. It sounded flat in comparison but we all expected that going into this. It was not bad sounding by any means but it was totally out if its league.

The Wyred 4 Sound came in 4th. It hits hard with good dynamics and bass but it was too bright and had a little grain. It sounded great with acoustic guitar with great attack, detail and resolution, but on rock music it was irritating and almost harsh. This was a surprise because I have heard it in my system and my friend's who owns both the Hugo and W4S and it did not sound that way. In fact it was one of the DAC's that I was considering buying up until this test.

The next 2 DAC's were a tough decision for me. I would call it a tie between the Comet and the Bryston, although the person that owns the Bryston liked it the best. The Comet has this unique 3D or holographic sound with a huge sound stage that is wide, deep and tall. It has great air and transparency, the best out of all the DAC's. It was actually uncanny in a good way on how clear and holographic it sounded. It reminded me of hearing a pair of higher end Martin Logan ESL's a few years back which I found to have tremendous transparency and a 3D sound. In addition we all agreed that it had a very nice midrange bloom. Bass was tight, fast and controlled but not as deep as the Bryston or W4S. Resolution was very good, better than the Hugo and not as good as the Bryston or W4S. Drums had very good kick and snap. Vocals and horns were smooth and very natural. We listened to Anne Bisson's Blue Mind CD using a Cambridge Audio 840 as a transport at the beginning of the test and her voice had good texture. All 4 of us however felt that the sound leaned a just bit to the bright side of neutral mainly on rock and roll. It sounded excellent when listening to Billy Mclaughlin's guitar on his Finger Dance album. 2 of us felt that it would be a great DAC for Jazz, Acoustic and Classical music.

The Bryston on the other hand did every thing well. It had a nice neutral tone, very good resolution, probably the best dynamics and bass out of all the dac's. It had a thicker or heavier sound compared to the other dac's. Because of this it did not appear to have the amount of air and transparency of the Comet. It sounded great with all types of music. It has good pace and rhythm and was about equal with the W4S in this area. The Comet was a little slower and the Hugo the slowest.

The Hugo Chord was the DAC that 3 of us preferred and ranked number one. It also does every thing well but it has a lush, liquid midrange and a more romantic sound. It sounds good with all types of music with out any fatigue. It was the most musical, smoothest sounding out of all the DAC's. It had good dynamic. It did not have the crisp detail of the W4S or the transparency and holographic sound and resolution of the Comet , nor the dynamics or bass of the Bryston but it sounded damn good. Some people may not like the sound because it can sugar coat the sound a little. Certainly if you are the type of person that likes a dead neutral and more clinical sound or razor sharp detail then it is not the DAC for you.

In the end, we all agreed that the Comet, Hugo Chord and the Bryston were excellent DAC's and each had it strengths and weaknesses. Clearly system matching is important. I had the Comet in my system for several days and it was very neutral sounding. However, I use a Pass Labs x250 amp, a BAT VK51se tube preamp and Magnepan 1.6 speakers. Personally, I could be happy with any of these DAC's. The Comet's holographic sound and sound stage is outstanding, the best that I have heard.

I will post a dedicated review of the Comet, its features, build quality and how it sounds in my system tomorrow. In addition I will have the Comet for a couple more weeks and I will try it with more traditional cone speakers (PSB and Monitor Audio) and post my findings.

If any one has any questions about the DAC's and the Comet in particular, please send me a PM.

If you look at other W4S reviews that used the Off Ramp, you'll see that they claim the DAC is bright too, the two don't play well with each other.
