Power cable for Bryston

Assuming he doesn’t want to spend too much, Cullen Cable is always a solid recommendation for price/performance. as is Audio Envy.  

CD players are not high current and don't need a huge power cord.  It is likely no improvement will be achieved (whether one is "heard" is a different question.  My car always seems to run better after i change the oil, even though I know it runs the same).

I upgraded all of my source components, including my REGA ISIS VALVE cdp/ DAC , BRYSTON BDP1-USB digital streamer- player, and BRYSTON BDA2 DAC to an upgraded array of CARDAS CLEAR and CARDAS GOLDEN REFERENCE power chords.

the step up in audio performance for each was not subtle, with the REGA spinner with its massive beast of a power supply ( cdp weighs ~ 52lbs) now mated with the CARDAS CLEAR power chord being the most prominent step-up in audio performance improvement

What’s your friends budget??

I believe Bryston Company frowns upon "hopped up" power cables. I was having a problem with my 4BSST2 amplifier where it occasionally go off on a safety lockout. I called technical support and they really drilled with me with questions concerning the power cord. They said the cords sometimes create the issue I was experiencing. I had the factory cord so that wasn't the problem. It turned out the unit was going off on a ground loop which I was able to correct. Perhaps they are too sensitive on that issue, but I thought I'd share my experience as I found it interesting.
