Best Line Conditioner

I have had 4 RSA conditioners and happily sold them all when I heard the Acoustic Revive RTP Ultimate. I use 2 of them now in my system and cannot say enough good things about them. I have been through so many PC's and can't stand what any of them ultimately do to the music (includes RSA). All have an initial wow factor but when you start to sort through the consequences, it is never worth it to me. The only other 2 I would even consider would be Sound Applications or MIT. My 2 cents.
