Price Paid:  $300.00 from EFE Technology

Summary:
I heard the Pro-One for the first time about 9 months ago when my wife and I visited EFE to demo some of their speakers. EFE's speakers were amazingly good, and we bought 5 of them, but we were totally blown away by a demo of EFE's Pro-One. You simply cannot believe the sound produced by the Pro-One unless you hear it for yourself. It makes music sound like you have the best seat in the house during a live show. And it makes movies sound accurate: if the movie has a car drive by in front of you, the sound matches it perfectly. All too often other processors make it sound like the car is behind you. I can't say enough good things about the Pro-One. The biggest problem with it is that EFE does not make many of them and it took me 6 months to get one. The Pro-One is the best piece of audio equipment I have bought. If you want "live" and "unprocessed" sounding music and movies in a surround sound setting, this is it.

Strengths:
Amazingly accurate and life-like sound for movies and music. Small size and no power requirements.

Weaknesses:
While not a weakness, you should understand that the Pro-One needs to receive an unprocessed stereo signal in order to work its magic. The Pro-One can't be placed on top of your amp.

Similar Products Used:
Processors and decoders built into various receivers; a separate DTS decoder.

Summary:
This little unit is a 5 channel, music "surround processor". The "processing" is purely analog...that's right, no power cord. I recommend this unit for audiophiles who like to hear music via five speakers. I know, audiophiles don't listen to their music through 5 speakers, that's rediculous, right?! Wrong. Clean, clear, unprocessed music. The main speakers deliver only a pure stereo signal, no processing there. The center delivers a mono signal of both right and left channels and the rear speakers an out of phase signal. (There is a little more to it than that, but if I told you any more I would have to kill you.) The result...unflavored, true to life (like all of his products), natural stereo imagery.
Again, I recommend this unit primarally for music listening but it blows away Dolby Prologic as well. Not quite the excitement of Dolby Digital. Lots of music DVDs sound great too.
It is a surprise to me that this breakthrough hasn't captured more listeners. If you don't have one, your really missing out on a wonderful experience. Highly recommended!

Strengths:
Cleanliness, ease of use, analog, spacial characteristics.

Summary:
I have owned/operated a Pro-One 5 Channel Surround for approx. 1 year.During this time I have compared its ability to AC-3 ( D.D. ) and DTS
decoders. I find the Pro-One to be superior for both music and movie
sound. While D.D. and DTS seem to send 75-90% of the dialog and music to the center channel the Pro-One spreads the sound out to make it more realistic.
While watching the Eagles, Hell Freezes Over in DTS,I see the drummer in front of me but the sound of the cymbals comes out of the rear speakers. Not so with the Pro-One it sets up a far more realistic sound stage. With the Pro-One I also
have several listening options 2,3,or 5 channel sound.
Because of its affordable price and great versatility.... and of course
great sound !! I rate this unit very highly.
