iceman94 Posted January 28, 2009 Report Posted January 28, 2009 I'm looking for suggestions of interesting DAC designs and/or PCBs/kits. I guess I'm shooting for the higher end of things, and PCM1704-based stuff has gotten my attention. So far I've found the Hagerman Chime and TentLabs kit. Any opinions on these? Anything else I should consider? Also, are there any standalone USB-I2S or analog output stage kits worth looking at? Thanks! Quote
Beefy Posted January 28, 2009 Report Posted January 28, 2009 Surely the Twisted Pear Audio gear is worth a look at. Quote
iceman94 Posted January 28, 2009 Author Report Posted January 28, 2009 Right, I forgot to mention them. As long as I could pair up a discrete transistor or tube I/V and output stage to it, I'd think about that. All I've found on the site is an opamp I/V stage, maybe I'm missing something. Quote
Beefy Posted January 28, 2009 Report Posted January 28, 2009 They have a discrete I/V stage in a second round of testing now, it won't be far away. That OPAMP output stage is surprisingly good though, and pretty inexpensive even if it is only temporary. Quote
n_maher Posted January 28, 2009 Report Posted January 28, 2009 I love folks who dismiss opamp based output stages without hearing it first. Quote
iceman94 Posted January 28, 2009 Author Report Posted January 28, 2009 Sigh. Let's rephrase things to "I'm looking for beefy output stages, Modwright-style." Quote
swt61 Posted January 28, 2009 Report Posted January 28, 2009 Opamps killed my dog just for spite. Quote
Beefy Posted January 28, 2009 Report Posted January 28, 2009 Let's rephrase things to "I'm looking for beefy output stages, Modwright-style." I've got your output stage, right here. *pelvic thrust* Quote
manaox2 Posted January 28, 2009 Report Posted January 28, 2009 I've got your output stage, right here. *pelvic thrust* Beware the low input impedance. Quote
n_maher Posted January 28, 2009 Report Posted January 28, 2009 opamps prevent you from returning my PMs, so i don't blame them at all Seemed like you were getting good advice in the thread. Quote
iceman94 Posted January 28, 2009 Author Report Posted January 28, 2009 I've got your output stage, right here. *pelvic thrust* Touche Now that we've gotten over the TPA lovefest, any other recommendations? Or thoughts on Hagerman or Tent Labs? Edit: that's not dismissive, I'm definitely going to look at the Buffalo and related stuff. Quote
iceman94 Posted January 28, 2009 Author Report Posted January 28, 2009 Also forgot to mention the K and K RAKK DAC... I guess, now that I stop and think about it, there's a pretty good field to start with. Any commentary on these designs? Quote

Pars Posted January 28, 2009 Report Posted January 28, 2009 I love folks who dismiss opamp based output stages without hearing it first. Oh but its true DIYHiFi.org • View topic - "Op-amps unsuitable for audio DAC I/V" - myth? Quote
