Best Line Conditioner

I'm sticking with Running Springs.
Don't let the price fool you. (Especially when comparing to bloated stuff like Tripoint.)
Given that every single internal part is made in house by one of the most internationally well respected manufacturers of extreme quality coils/transformers/and capacitors. AND given that they reserve their absolute best designs of these parts for themselves. AND given that the company uses a relatively low margin. (read: fair pricing, not bloated, "I'm king of the hill" pricing.)
You're getting more than $35,000 dollars worth of performance from RSA.
Oh, and doing it longer? Well, let me put it this way.....
My high school science teacher may have spent 20 years working on some cool project. But if I need it to work properly, I'm going with the Physicist whose wall is covered with peer granted credentials and awards.
Look up the article than ran in TAS last year regarding the RSA Dmitri. You'll see there really isn't a more qualified outfit than RTI Electronics to build isolation devices.
Dems the facts Ma'am.

Prdprez,

So I shouldn't sell my DMitri for the SR Powercell 10SE? Sidestepping am I?

Yo Erasto. IMHO expensive power conditioner mfr's prey on the well known audiophile bias toward more $$$$ equals better performance. This may have some merit with speakers, amps, and players but the point of diminishing returns is reached quite quickly with accessories and then drops off a cliff. Accessories are where dealers make there bread and butter. I live in the boonies where there are no dealers to support so I'm an online guy by necessity. I doubt you will do much better than what I use: an APC H15 power conditioner with 12 outlets, 1440 watt electric power capacity, and a silver face (to match my components, of course). The outlets are engineered to keep digital, analog, video, and high current loads (power amp & subwoofer) and their electronic noise separate from each other. It also sepetates and protects telephone, data, CATV and satellite connections. The sound of my system is quieter with this unit and I am confident it will work to protect my system from power surges or sags, though I will be quite happy to never test that hypothesis. Right now there is a very good deal for this unit at Tiger Direct for $200. The 1000 watt unit (H10) is $100. If you don't use it for a big plasma TV in addition to the stereo eqpt, 1000 watts is usually adequate. That's my two cents for now. P.S. I'm an IBEW trained electrician with thirty years under my belt and a lot of engineering classes thrown in to boot, so it's possible I'm not completely out to lunch. That being said I'm sure I just put on a t-shirt with a bulls eye on the back for some of the 'goners on this site to shoot at. Anyway, do your online research,etc. and go for it. Good luck.

Some say that the Clarity Cable's 3D Max power conditioner is really good.... http://www.audioasylum.com/audio/cables/messages/13/134159.html

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.
