Where to put one's best power cords??


, Where should one put their finest power cords? Mono amps, preamp, DAC or transport?  Where will the best cords have the most impact?  Thanks, Jeff

John Rutan at Audioconnection recommends putting the best cable on the source- For me, my Ayre Codex DAC.
I have some AQ Thunder due to arrive shortly.

Some power cords work best on amps and some on sources gears.  For example, when I put my finest power cord on my DAC or music server, it didn't sound as good as my other power cord that's made/designed for source gears.

Depends on equipment and cords. No definite general answer. Listen. I would start by putting the cord on the preamp first, then move upstream step by step. After that to power conditioner if you use one and then to power amps. Unless specifically designed for digital, transports and dacs, good heavy gauge cord should work well everywhere. Purist Dominus cord that I have works best everywhere ! I left it on the integrated unless making recording from vinyl to tape - then I put it on the phono stage. I record directly from phono, no tape-outs.
