Nordost Quantum Technology Products

FWIW, i have owned the Nordost Thor and am in the midst of upgrading to qx4 having heard it. the best way i can describe it is that certain passages within complex music suddenly become even more "understandable" and clear. For example, on certain ;arge orchesteral compositions, when i put the Thor into the system, i realized that parts of the orchestra were actually playing a sort of contrapuntal counterpart to the other part of the orchestra. Nor sure why, but before the Thor, I had never made the musical connection before despite listening for several months to the CD. There is something very clear, organized (and effortless) about the way the music is presented that I feel like it is easier to listen to all of the various complex passages at the same time and keep them all going without "bleeding" together with the Thor...and soon the qx4. One man's experience. hope it helps.

There seems to be a change of view where to put one Quantum unit in the chain. I thought before the power conditioner to include the whole system. Speaking to a Nordost rep at the UK show last weekend, he said put it in front of any unit with a low current draw, say the CD player or phonostage. It will still help the whole system, particularly if somewhere in the middle of the rack and you avoid tyhe risk of excess current demand through the Q4

That is good to know. I met Roy Gregory in London a few months back who is now with Nordost, and he suggested i try both ways...entire front end (not amp)...and directly in front of my DAC.

i will post upon hearing. Have elected to upgrade speakers so that is (fingers crossed) going to be done in a week or so...they arrive 22nd i am told. fingers crossed!! thanks for your advice.

Van1,

The Quantums in question here are not HF noise filters. They are designed to be used with or without noise filtering PLCs, or any type for that matter.

You are right about many high-end components not needing additional filtering.

However, there are other types of PLCs that address power factor correction, quantum noise, and electronic artifacts, not normally addressed by conventional filters or transformers.

I own some earlier, less expensive Quantum products, and they give a small improvement when placed in certain areas of the system. The Qx2 and 4, I have heard at a show, no A-B demo was done, so I can't say how effective.

Finally got my trade-in speakers! Expect to have the Nordost QX4 (part of the trade) after the New Year. will post.
