Best place in the system for a good PC?

* Price doesn't determine value or synergy of anything.

* The PC of choice is component specific and is generally enhanced by perpetuating the grade and type thoughout the entire system loom.

* If you have audiophile friends or a local dealer, barrow several cords and experiment. Have fun.

* Only you ears, in your system, in your room, will answer the question of sonic value definitively, nothing else matters.(period) IMHO

...and yes, to my ears some power cords make a positive difference.

Happy Listening!

ABX is tough in my case. I'd like to compare and contrast mainly on my amp, but it's a tube system and by the time I warm up, listen to A, turn it off, cool it down, switch the cords, and power it on and let it warm up again... well, it'd have to be a big change for me to notice.

The cables I'm going to try are the Zu BOK and Zu Birth (mk1 I found here). The team at Zu work hard to please and I've always been pleased with their analog & digital cables so I'm going to give them the first crack.

Thanks All.

I don't use ABX to evaluate components (including cables). I prefer to change a component, listen to it for several days, up to a week or two, and then switch. Repeat as needed.

Some differences may discovered immediately, while others are subtle, and take time to learn.

I think that's often the problem with quick ABX testing. Too short of evaluation periods with strange gear.

for what it's worth, my zu bok made no difference vs a generic PC

In my experience, a high end power cord made the biggest difference on my amp, then my source, then my preamp.
