IME I noticed the greatest improvement in SQ (more believable micro dynamics and imaging) from installing a Zavfino Fina PC on my streamer. I started with DAC/PRE first (also a Fina), then the power conditioner (Acoustic Zen PC) and amps (Merrill/Cardas PC). Everything made an incremental improvement, but I really heard the most when I upgraded the PC on my Zenith. Thanks to @thyname for the Zavfino recommendation!
Dac or Power regen, which gets the better cable?
I have fairly decent power cords on all my components (Virtual Dynamics). I have a new PC coming in which will allow me to swap a better power cord out on either my DAC or PS audio regen. Which would it make most sense to put the better PC on? My brain is sayin the DAC…thoughts?
