Yes. I gave it a try and it uses a Burr Brown 1704 like Audio-gd DAC19, Ref1 and 7.

No words for the moment, but I hope the pictures speak for themselves as a first look. The box arrived 5 hours ago, the dac is already connected and I have been using it instead of the Lyngdorf DPA-1 which I was using as my main dac together with a naim dac. I have decided to do the testing on my speaker system rather than my Stax rig, as much as I love my Staxen, they cannot even approach the feet of my Kharma CRM 3.2FE's.

So far I have noticed a wider soundstage in a laid back kind of way vs the Lyngdorf. Also there was significantly less bass impact with the Ref. 7, however this is changing fast. It only has been playing for less than 4 hours, I really dont expect much at this stage. I will of course continue to post my impressions. CLICK AT THE LINK BELLOW, Enjoy!

With your speaker rig is definitely the go.  I asked Kingwa via email how long he'd run it beforehand, and he said about 200 hours. I'm definitely looking forward to your impressions in a week or two after you've run it a while.

It takes time to get acquainted with these 'sophisticated' electronic machines, Im just starting to understand its language and I'm liking its accent. I'll try to write some less abstract impressions in the following days...

Impressions?

post #51 of 370

Gentlemen, I have had the DAC for a bit more than a week, I dont know about you but I doubt someone can give good impressions on equipment in such a short time. The time agreed was around 2 weeks per person and I plan to send the dac to Monkey either this saturday or monday.

 

So for those of you that want to know what Im hearing I have three quick observations:

 

1. The DAC is very organic, it texturizes music and at the same time defines the space around the textures. Of my DAC's (transporter, lyngdorf and naim) the GD is the fullest and has the most musical dimension.

2. The DAC is neutral and clear, but not as defined as the naim and lyngdorf. With this I mean that the instruments have less rendering precision with the Audio-GD, thus making them sound more relaxed (in a good way) and perhaps tend to be more realistic, making the others sound more hi-fi'ish.

3. The instrument separation of the Audio-gd is on par with the naim and lyngdorf, but the GD is more spatial, more open, again I will use the words 'organic' and 'fuller'. Bass definition in the naim is better if you prefer dryer, tight and fast, the GD is neither of these. Its more wholesome, neutral, relaxed and natural.

4. I think I want to buy the unit... there's something about it which I still cant pin-point

 

Of course more impressions will follow,

Interesting write up, thanks.

post #53 of 370

Share a lot in common with the DAC19 DSP it sounds like.

post #54 of 370

Did you compared DAC19DSP with RE-7?

 

I'd be interested to read about that.

I actually only like to listen to things for no more than a few minutes at a time. If I can't form an opinion quickly, then I simply accept that I have no real opinion. Imo, spending long periods of time trying to find subtle details simply gives more opportunities for your brain to play tricks on you. Am I alone with that kind of thought process?

I use the Ultrasone CD and Chesky Records - The Ultimate Demonstration Disk to test my DAC, AMP, and headphones/earphones. Also it would take more time to test all the different genres of music I think.

You're not alone (I've know others who feel the same), but I disagree with this methodology. For large differences, A/B testing is great, but for subtle differences, I really need longer periods of time. It's also true that the longer you listen to something, the more psychacoustics kick in, but it's not as big a problem as you might think.

 

Am I correct in assuming that you have difficulty hearing the difference among cables and even similarly-priced DACs? I ask because I feel both of these things can produce differences subtle enough where they go unnoticed with <30s A/B testing.

Sometimes I hear differences, and sometimes I don't. Either way, I put a lot more faith in first impressions than one-week-later impressions. <30s generally isn't enough for me either, but if I can run a few passages from a few favorite test tracks, I feel pretty confident.

post #59 of 370

Well for cables I can hear the differences better if I'm allowed to look at the thing itself. Meh, I'm not a 100% cable believer anyway.

GuyDeBord, do you have any room treatment for your speaker system? If not, have you tried measuring your in room frequency response and waterfall graph?
