January 28, 200917 yr comment_200541 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! Report
January 28, 200917 yr Author comment_200547 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. Report
January 28, 200917 yr comment_200549 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. Report
January 28, 200917 yr comment_200559 I love folks who dismiss opamp based output stages without hearing it first. Report
January 28, 200917 yr Author comment_200566 Sigh. Let's rephrase things to "I'm looking for beefy output stages, Modwright-style." Report
January 28, 200917 yr comment_200584 Let's rephrase things to "I'm looking for beefy output stages, Modwright-style." I've got your output stage, right here. *pelvic thrust* Report
January 28, 200917 yr comment_200586 I've got your output stage, right here. *pelvic thrust* Beware the low input impedance. Report
January 28, 200917 yr comment_200598 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. Report
January 28, 200917 yr Author comment_200604 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. Report
January 28, 200917 yr Author comment_200631 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? Report
