Get Power Conditioner -downgrade my expensive PCs?

Snofun,

Bryston states that they believe "filtering" power cords impact the 60hz AC current, therefore reducing the performance of their amplifiers, which implies that they do believe PC's make a difference, but that in their opinion it's a negative one. But since they don't specify what they consider to be a "filtering" power cord, it's a pretty meaningless statement. All cables "filter" based on their LC values. So either Bryston thinks that the LC values of their supplied PC's are ideal, or they're simply not making a thorough enough statement of their opinion for me to debate the facts.
I could take two of Bryston's supplied AC cords, and cryo treat one, and even you could hear the difference, if you bothered to listen. So is Bryston wrong? In my opinion, absolutely.
As for Pass Labs; I don't know what they have to say about PC's, and I doubt debating their opinion would change anything, so I won't bother.
As for my comments about DBT testing of amps, I was simply referring to the fact that there are those that believe that any two similarly spec'd amps sound the same, and that DBT proves it. And since you're indirectly advocating DBT, I just thought you'd like to address the issue of why you bought a Bryston amp, when you could have bought a Crown pro amp with similar (or better) specs for far less money. Did you buy the Bryston because you believe it sounds better, or just for the warranty?

Bryston's wrong, Pass (by association) is also wrong. Man, to be an Agon expert. Is there a test to take, or is it just a self-annointing thing?

Note also I wasn't indirectly advocating DBT, I was directly advocating it. Usually those who are most against it are the ones who have the most to lose in their proclamations and insecurities.

I bought the Bryston because I like the color of the lights.

Snofun3,Or not, My suggestion to call the manufacturer was just that, "a-suggestion". Some times the use of a contact point can help you come to conclusions which will work best for you and your particular set-up and needs. Nothing in this hobby is written in stone as you seem to suggest in your responses. If I happen to find a piece of equipment that works for me I will purchase it, regardless of whether or not somebody thinks contrary to my opinion. Freedom of choice is good,so have at it...

Aolmrdl - I completely agree with your suggestion.

I was just pointing out how respected manufacturers, with intelligent engineers and designers, who have produced esteemed products over decades of experience, and assumedly spend many hours and $ testing their products under varying conditions and environments, are quickly degraded if their conclusions don't match that of some hobbyist.

Again, I agree with you, and I was only pointing out what became reinforced soon after making the comment.
