What is your approach to system fine tuning with cables and cords ?

"Everything already sounds quite good, no obvious weak links."

That's when I'm done.

n80, you never sound like an audiophile, and as such this thread cannot possibly concern you. You simply don't get it.

Yeah, n80 doesn’t sound at all like your typical insecure neurotic hypochondriac!

Um, room tuning first, talk to GIK Acoustics and Michael Green.

Next, move any wall wart / AC adapters out of your power conditioner's clean outputs.

Evaluate your image. Are instruments able to smoothly go from left to right, or is there a L, R and maybe a center? Is there a sense of height?

PS:

I use the rack mount version of this inexpensive strip for the wall warts:

They filter noise down to 3 kHz, and have great surge suppression. If you use them for the little noisy adapters they add one more filter between your main power conditioner and your analog gear and DAC.
