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.

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.
I used the Running Springs Audio Danielle and Duke with good results until I bought the Sound Applications. There are no comparsions and I would highly recommend trying the Sound Applications before spending big $$ elsewhere. The combination of dedicated 20 amp circuits with Oyaide R1 receptacles and the Sound Applications mated with a Kimber Palladian PK 10 took my system to a whole new level. Nothing gets in the way of the music just pure power with `life like` you are there presense.
Samzx12,
Yes I have tired the Running Springs (Audio Dmitri). Without going down a long laundry list here are a few impressions.

The Running Springs does a very nice job of cleaning up the highs while preserving detail and air. So too does the PowerCell 10 SE.

The Running Springs did not limit bass in my system until I added another stereo amp and auditioned in bridged mono- the PowerCell never limited bass and even added to dynamics compared to the direct wall connection, even when running amps in bridged mono.

Where the two (and every other power conditioner I have tried) differs is in the PowerCell 10 SE's uncanny ability to separate the soundstage from not only the speakers but also from the room itself. The degree of holographic realism is hard to fathom; at least that was the case for me in my system.

Power conditioners are like cables and power cords i.e.: you've got to hear them in your system for a week before you can reach any meaningful conclusions. At least with the PowerCell it’s not too heavy (in case you have to have one shipped to your home.) I’d say the top three to audition would be the Running Springs Dmitri, the Synergistic Research PowerCell 10 SE, and the Audience aR12T, at least these are the three I found to be the best of the best.
