Is high end Power Conditioners worth the extra $$$

The best conditioners I have heard are the Running Springs line.

To answer your querries:

1.Both Shunyata V rays V2 and The Audience T offer significant improvements from their previous models.If you have an extensive listening comparing both the old and the new versions,I am sure you would upgrade to the new ones..

2. Both of the Shunyata and Audience have sonic signitures of their own;your systems might need them and you would love it.Mine don't.

3.Having listened to most power conditioners,I firmly believe and convince that correctly applied,and your system has been optimized,'passive 'conditioners are better than their regenarators counterpart.

4.If you can,check out the VERTEx AQ range;they are just superb,especially if you use it in all Vertex cablings.Perharps the best in the world right now.........

Yep...The Bybee is by far the finest AC conditioner Ive ever used..
In comparison it made the Audience AR12 it replaced sound broken!

Jack Bybee is a genius,imo.

Again,
All power conditioners are at least as system dependent as audio cables. That said, the SR Powercell is the only line conditioner that has not limited current in my systems (or to my amps).

The Absolute Sound also highly recommends the SR Powercell.

Worth an audition.

Shellie...Have you tried Running Springs?
