Will be soldering ics to pcb in a bit. I am also altering my reg pcb so that all voltage lines are isolated from each other.

Hang on, I killed the headphone out....

Now then....

I am so happy

I have revised my reg pcb quite heavily and now run seperate regs for Digital , Analogue , Clock and DAC clock voltage rail.

Also I have fitted two Audiocom regs next to the op amps.

And soldered my chips to the browndog pcb's with silver loaded solder.

First of all I listened to it with just the regs sorted and OPA2134. There was a better clarity, not a lot but enough to notice, it just seemed more open, more air etc

Then I fitted the Browndog OPA627 , OPA132 pcb to one channel and tested against each other using the balance.

Whhoooo

I had independant listeners doing a blind test and everyone said how much clearer and better the right hand channel sounded. And it was much better, no top end nasties compared to the left channel, a much tighter bass and the clarity wow!

So incase you have not guessed the right channel is the OPA627/OPA132 combo.

cheers 6h5c for the advice on the combo and cheers to simon who kept telling me the OPA627 was better

So here are a few pics.
