Is high end Power Conditioners worth the extra $$$


I am already using an audience AR6 which has given me good improvements together with a dedicated power line (with Oyaide wall outlet). I am still separating my power amps (Rowland 500) to a separate distributor to the wall.

There seems quite a number of higher end power conditioners like the AR6T, Synergistic Research 10SE, Hydra V-Ray V2, etc that are on the market. I would like to poll people who have had experience already with power conditioners and have upgraded to these units and would like to know what it brings.

In my system the Synergistic Powercell 10SE dramatically expanded the soundstage as well as dynamics while lowering the noise floor to what seems like ZERO with more air and enhanced detail and musicality.

BTW I went to RMAF and noticed that in the SR room they had two 1000 watt monoblocks (along with the entire system) plugged into a single PowerCell and their room sounded effortless and had room shaking dynamics. I saw no other high powered systems plugged into a single power conditioner, let alone one with such power and finesse. This suggests the PowerCell is in a class all its own. It's certainly worth an in home audition against other conditioners- that's what I did before making my final decision.
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.
