Anyone who spends more then $10 on a USB cable is a sucker. IMO. The encoded audio data sent over a $10 cable can not possibly sound any different then sent over a $100 or $1000 one.

Is three OPA2134's a resonable configuration, or should I consider purchasing some of the other op-amps posted in this thread? So far this sounds much better then the stock op-amps. The highs are a bit on the harsh side, that is my complaint.

I just popped in three BB OPA2134PA I found from a past active xover project. I also disabled the 250% gain. The first minute impressions are: - Much much brighter, sharper highs, almost too bright will need to get used to it. - Bass is stronger, but a little muddy, although I'm...
