Good question Teejay! My reference power cord is Siltech Signature G6 Ruby Hill and it is excellent sounding with Weiss Medea DAC and Weiss Jason CDT, much better than PS Audio Statement Power X-Stream that I previously used.
With Esoteric DV50s I use Acrolink 7N-PC7100.Also, I had a chance to try new Acrolink 8N-PC8100 with Esoteric D-01/P-01/G-0s and it is even better than 7N-PC7100. Strangely with Esoteric DV50s Acrolink has slight edge over Siltech but, with Weiss situation is reversed. In my home I use separated power lines for amps and preamp/dac/cdt. Preamp and dac are powered from dedicated 20A line, power amps from two dedicated 30A lines( my electrical guy thinks I am crazy!). I spend a lot of money for new in-wall power cables etc. Experience with Shunyata Hydra 8 was a strange one, sometimes it almost muted dynamics...
In my office I use PS Audio P500 and there it works well.
But, in general I have very mixed feelings about power conditioners... Good after market power cords are essential IMO to get the best out of our DACs/CDts or CDPs.
BTW, the biggest difference in my system are dedicated power lines. Once you have it, you can not live without it!
