Anyone tried Quantum Resonant Technology?

I recently tried some major power supply upgrades recommended by my local dealer (Vineyard Sound.) I'd been swapping $1,000 interconnects and power cords when Michael suggested a Resonant Technology QX4 and QB8. I have to say up front that I am going to have to downgrade something in another area of my life to keep these components in my system.

The QX4 and QB8 greatly improved highs, spaciousness, attack and decay. Any sense of brightness or grunge disappeared, and I have a much cleaner, wider and deeper soundstage (added 6 feet easy) I've also noticed that I am listening to more music, everyday, for longer periods (the true test for me.)

I don't know the technology but in my system it creates more magic in between my speakers than any other conditioner, tube or cable upgrade I've done. It adds much more energy without removing anything relaxing about music.

My realization is that this technology is more of a foundation that provides the right power to make the recordings sound real. Good recordings sound better, great recordings are in the room, bad sounds okay, still kind of bad.

I'm very impressed and can easily say this combination added 15-20% vs the 5% upgrade with other power supplies changes from quality companies.

Anyone else feel this way or tries these? I've heard little about the Quantum gear other than Nordost is the distributor.

Brian,

I did not try the QX4 with the QB4. I did use it with my $3,000.00 reference power conditioner.

I chose my reference power conditioner over all of the other big names that I auditioned and had it for five years.

In total, I had $5,500.00 in my power conditioner and QX4.

I have had my qx-4 for a year and I am very pleased with results. I originally placed the qx-4 in an adjacent power plug to my PS Audio PPP and the improvement was like a major tweek, but tweek none the less. After plugging my PPP(Power Plant Premier) directly into qx-4 and centering it in the middle of my system the difference has been equal to a major component change. It comes close to equaling the marked improvements I heard after extensive use of vibration control devices(Vibraplane, Svelte shelves,StillPoints,Little Rocks,ect.) It dovetails with everything I have tried it with,such as Shakti Stones,On-Lines,VPI brick, Premier Soloist. There is no downside I can discern.I could go on and on about the positives, but I am a very slow typist,ergo, to the point, very highly recommended.

I can't speak for the Quantums, but in my experience,improving on the power source has been more beneficial than attempts to improve my sound with speaker and interconnect upgrades.

And cheaper.

I have to agree with Krell_Man. If you can find a topaz isolation transformer you'll beat just about any conditioner on the market. I recently listened to the Tripoint Audio Spartan ($35k) power conditioner and I honestly don't know that it's any better than the isolation TX. I currently own three isolation TXs and couldn't live without them for what they did to my sound.

I must also mention that Krell_Man was the great guy who first introduced me to them.

They have come out with the QV2, a plug in unit and a lot cheaper, retail 375, offer similar improvements may be to a lesser extend, since i never tried the Qx models.
