DefectiveAudioComponent Posted April 8, 2010 Report Posted April 8, 2010 I need to get a new DAC after damaging my E-MU 0404 USB dac. There are nice new (used) DACs out there for about 200 euro, the E-MU, the V-DAC, and the cambridge audio DAC magic. But there are also vintage DACs, like this ADCOM 700 (that someone seems to have done some strange mods to) [ATTACH=CONFIG]2965[/ATTACH] or the Parasound D/AC 1000, or this Orelle DAC [ATTACH=CONFIG]2964[/ATTACH] What do you people think? Should I go vintage or almost new?
Knuckledragger Posted April 8, 2010 Report Posted April 8, 2010 I got an "invalid attachment" message for both of those.
spritzer Posted April 8, 2010 Report Posted April 8, 2010 The attachements aren't showing up but a vintage dac any day of the week for me. You might have to recap it but that's not a big deal.
The Monkey Posted April 8, 2010 Report Posted April 8, 2010 Having just gone through a similar exercise, I would recommend the vintage DAC path. However, just because it's vintage doesn't mean you're going to love it. If you can afford a new DAC and a vintage DAC (or if you can demo a new DAC), then that would be ideal. Really, the only way you can make an informed decision is to hear them for yourself. I've found that it is very difficult to get an idea of the sound of a source based on reviews.
DefectiveAudioComponent Posted April 8, 2010 Author Report Posted April 8, 2010 How odd! The pictures were there in the preview... well, I'll try again: [ATTACH=CONFIG]2966[/ATTACH] [ATTACH=CONFIG]2967[/ATTACH]
Pars Posted April 8, 2010 Report Posted April 8, 2010 For the Adcom, the film caps with long leads is pretty questionable. Better to use a DC coupled discrete stage instead of mucking with opamps and coupling caps. The copper tape shielding is fine, and does appear to be grounded. No idea on the other DAC.
cetoole Posted April 8, 2010 Report Posted April 8, 2010 Agreed, and even if you stick with opamps, I see no reason why there is the need for the big flying coupling caps. PCM1702 has output around 0v, dual rail opamp supply, so opamp output should be around 0v (minus various tolerances). If it is too far off, it is easy enough to servo.
spritzer Posted April 8, 2010 Report Posted April 8, 2010 I personally wouldn't touch that Adcom though I must say I like that copper shield between the PSU and the main circuitry. Also replacing all the film caps with Wima's yet leaving out the aging electrolytics...
DefectiveAudioComponent Posted April 10, 2010 Author Report Posted April 10, 2010 I'll leave that particular Adcom alone then... How about a Micromega DAC 1? Or an MSB Digital Link 3? Those two would also fall into the right price range for me.
Currawong Posted April 11, 2010 Report Posted April 11, 2010 Micromega made some nice CD players...back in the early '90s. Not sure how any of that gear would stack up now without knowing what's inside it at the very least.
jp11801 Posted April 11, 2010 Report Posted April 11, 2010 I loved my Micromega stage 2 cdp that I had from probably 95 to 05, dodgy drawer mechanism that squealed and opened and closed on it's onw accord but sounded great none the less.
DefectiveAudioComponent Posted April 11, 2010 Author Report Posted April 11, 2010 This links to a picture of the Micromega, from someone trying to sell one with Burson opamps installed: http://www.canuckaudiomart.com/image.php?image=1225964&is_user=0 ( I think the Burson opamps is the boards at the back, but I could be wrong. I could be even more wrong, if the picture is of the CD transport... but I can't see any disc drive in the picture.) How does it look?
DefectiveAudioComponent Posted April 11, 2010 Author Report Posted April 11, 2010 Older versions (around 2001-2005) of the Harmony Design DA9 would also be close to what I'd like to pay. ( Harmony Design ). (the oldest are cheaper, the newer usually a bit more) Upgrading to the latest version costs about 200 euro so that is not an option (usually cheaper to buy a new one then).

DefectiveAudioComponent Posted July 30, 2010 Author Report Posted July 30, 2010 The cheapest DAC I could find at the local junk store was an old and heavy JVC Ambience Synthesizer from '89. Too bad the ambience can't be played through a normal 2ch headphone.
DefectiveAudioComponent Posted July 31, 2010 Author Report Posted July 31, 2010 The ambiophonics syntesizer effect from the JVC DAC is not supposed to work through headphones. But I maybe it could work through open-back headphones for the stereo source combined with speakers to play the hall ambience. If that works, it could be a convenient way of improving headstage.
DefectiveAudioComponent Posted October 22, 2010 Author Report Posted October 22, 2010 I'll just go on and on here with my monologue. Now I've just got a '95 DPA DX16 Rennaisance DAC. It's got a nice green led on it. Looks good.
blessingx Posted October 22, 2010 Report Posted October 22, 2010 To make it a dialogue: Greens good. I had a plain cheeseburger for lunch.
dBel84 Posted October 22, 2010 Report Posted October 22, 2010 I love my transdac if that makes you feel less alone ;-) ..dB
DefectiveAudioComponent Posted October 23, 2010 Author Report Posted October 23, 2010 It looks well made with it's thick steel case and steel front plate. Probably the case itself is worth what I paid for the dac. As a bonus, it features one useless optical deltran clock sync output for jitter free transfer. I am curious about what the ancient DX16 dac processor can do to the sound. Apparently DPA made it and only used it in their own products. The on-off switch is tempting.
DefectiveAudioComponent Posted October 24, 2010 Author Report Posted October 24, 2010 Time for first impressions! Power on! Optical cable connected to mac book pro Green led: ok Sound: only static Checking sound preferences.... optical digital 16 bit/48? Switching to optical 24/48... sound: ok
DefectiveAudioComponent Posted October 24, 2010 Author Report Posted October 24, 2010 That wasn't my best photoshop moment. Now the nice shiny metal case should be visible. Thick heavy metal )
Happy Camper Posted October 24, 2010 Report Posted October 24, 2010 So how does it compare to the newer stuff? I've been using an old (95) CAL dac since finding it in the closet. The meets have not given a (gotta have) moment compared to some newer dacs. In a couple weeks I will get a chance to hear the A GD unit and am keeping an open mind to justify spending close to 2k vs 200 spent on the CAL. Now those LCD-2s are another matter. Love to get a listen to keep me away from a stat rig.
DefectiveAudioComponent Posted October 26, 2010 Author Report Posted October 26, 2010 Good question... I've got no high end gear unless the Arcam cd73 player counts.... But it brings out a nice airy sound from the LCD-2 so it appears to do the conversion as it should. I need to listen to some more music to hear if it has annoying flaws. The seller said it's basically unused (and it sure looks brand new) so it's not even burned-in (the manual recommends a whole month for burn-in ) Components could start breaking down anyway with age I suppose....
