BPT 3.5, Audience aR12, or Equitech 1.5Q?

Eugene81,
I have`nt heard 2 of the the 3 choices.The BPT 3.5 I `ve owned for 3 years and it is superb. My entire system is plugged into it and the sound improvement is substantial. Every parameter improves with it`s use and I`ve yet to find a negative tradeoff. The noise floor is much less, this allows the music more nuance,dynamic flow/ease and there`s improved 'natural'tone and dimensionality.The overall presentation is larger in scale and improves realism in my experience.

Balanced AC power has become absolutely mandatory now.
I `d think the BPT and Equitech are very similar in results. My BPT is silent and has no hum issues.

I`ll defer to you since you have experience with all 3 units. I just assumed the Equitech would be quite similar to my BPT 3.5 Plus(share balanced AC concept) I guess I was wrong.You are right, amplifiers are better with the BPT than when I had them plugged in my wall(dedicated line with 20 amp service).This is true for my 8 watt SET 300b amp as well as my previous 100 watt push-pull tube amps.

Grannyring congratulations! this product is worth every penny.It`s one of the most cost effective audio purchases ever for me.It improves naturalness and realism as well as reducing (significantly) hifi-ish artifacts and character.
