will you be updating your cd player thread or consolidating all the info on putting it together an dgetting it running in to a single post/webpage?
I've been updating the first post in that thread sporatically over the last couple weeks, mainly because I'm actually using the result of this as a paper for an audio engineering course. I have to polish that off by Thursday or Friday, so hypothetically I'll be able to have the thread itself almost finalized by then.
This is ongoing, though, because there are a few tweaks I want to try. After the Dynahi gets finished I'm going to think about cleaning up the clock signals for the DAC and transport. Eventually I might get into damping as well, depending on how much buzz/hum I get from the power box.
OPA637's on left and right channels / OPA627 on ground channel
Double stacked buffers on left and right channels / Single on ground channel
Class A bias
1000 uF Panasonic FM power supply caps.
Alps "Blue Velvet"
Vishay Dale resistors
0/75 Ohm impedance switch for output
PPA style bass boost implemented on a dip20 socket.
After listening to it all weekend, I am extremely satisfied with how it turned out.
if you dont mind me asking, what case is that?
thanks
I just wanted to try something other than the usual opa213x.

It's on the pricey side, but the specs don't look like anything spectacular... is the sound worth the cost?
Well, I've heard people say that it's almost like a dual version of the opa627 because they are both Difet opamps. I think that's why it costs so much. As far as sound goes, my headphones are crap so I probably couldn't tell the difference between an opa2107 and a tl072.
