Nordost Quantum Technology Products

Hi,Lloydelee21, Just picked this up. I agree with absolutely every thing you say. The Q's reveal a musicality that I always missed in Hi Fi. And yes,.. why would you mess about turning them on and off! Just relax and listen. A life time in professional audio helps me not all to understand how these gadgets work. Radiation? Of what? Why can't we detect it! Rare metals at work, maybe?

I have persuaded my local hi fi dealer (that I got my ATC amp and Harbeth speakers from ten years ago!) to come by soon and take a listen. He now deals mainly in Naim gear and was unimpressed by the Thor a while back. I think he will be re-impressed.

If anyone knows what's going on with Quantum and Nordost do tell. The website has been same for nearly two years.

Re. Stands. I just bought a pair of Something Solid stands made by Mark Orr. Rigid light weights replacing my ancient massive Cliff Stone Foundations. Nice tighter bass, crisper timing. Excellent for 200 GBP.

I think vibration and resonance problems will be specific to any set up. I have used inner tubes and home made cups-and-balls to deal with the problems caused by the wooden unit in which I hide my gear from my wife.

Minute changes of these items can effect the whole spectral balnce of the sound in very audible ways. Presumably any vibration of equipment must modulate the sound.

Hey, Lloydlee21 get back to that music!

Hi Apshift,

Glad to hear you are enjoying Nordost! Have your ever found HRS damping plates or EAT tube dampers? I have bought both (mainly s/hand). Tremendous at dealing with airborne and physical vibration in cabinetry/equipment. I was stunned frankly at the improvements from both.

I stuck one on my DAC, and when my girlfriend tapped on it, she thought it was solid metal. i removed the HRS damping plate, and she tapped again...rang like an empty tin can. She was stunned. S/Hand these are extremely useful for the money.

EAT Tube damper equally good in different way.

I have 3 Qx4 in my stereo system and 1 for my HT system.
They are extraordinary devices, but needs attention regarding where to place them and what cables to use and how.

I thought first that it was most important to have a good AC cable into the Quantum, but the most important AC cable is actually the one coming out of the Quantum. My dealer has shown this with Magus AC into the Quantum and Odin out, which sounds spectacular.

You should also try to have damping devices under the Quantum and also place them as close as possible to your gear, the best is to have directly above or beneath.

I have Qx4 in combination with my Burmester 948 AC conditioners. I have found that it is best to have the Quantum after the 948 in the chain.

In my system specifically I have 1 one Qx4 between my 948 no.1 and preamp and 2 between 948 no.2 and monoblocks. I would like to add one also for cd player.

Hi Cappuccino,

wow...great feedback. I have one at the moment...from wall into QX4 and then into Transparent Ref Conditioner...all my pc's are Purist Audio Ann Contego/Dom Ferox, plus 2 Sablon Audio PCs.

i do not have it under damping device per se, but it is on a custom built rack which is quite inert (3" thick birch ply on top of 1" thick slate).

enjoy!
