Differences between various Quantum devices

I realise there has been some discussion of Quantum QX4 and QX2 devices. I have seen them at several shows and am sold, personally, on the gains envolved. They are not cheap, but I am all ready to pay for a QX4 and I find new alternatives. Firstly QRT themselves are producing a QV2, a small plug in device for sockets and conditions. This evidently is not the same as QX4 and 2, it uses different technology. Kemp as well have the much cheaper plug in QA plug. So what do I do know?

A big ask I am sure, but has anyone compared the differences and merits of QX4 or 2, with the QV2 and Kemp plug. I would prefer the latter if it works as well, partly for the cost, but also it means I don't have to find room for another shelf in my rack. Thanks David

David,

I had a QX4 for a while, but I don't have it any longer. Did it do something good? Yes. Do I think that's it's worth $2,500.00? No. If you go that route and do as Nordost suggest, you'll keep adding QX4s at $2,500.00 a pop.

Did you see this post: http://forum.audiogon.com/cgi-bin/fr.pl?htech&1264477351&openusid&zzLiguy&4&5#Liguy

Liguy is an electrical engineer, notice what he says about the QV2. If he is indeed correct, then there's a cheaper alternative.

Right before David Magnan's website went down, he recommended using three Enacom AC filters on the AC line with your system: http://store.acousticsounds.com/d/55403/Enacom-Enacom_AC_Line_Noise_Eliminator-Line_Conditioners

That's $225.00 for all three. I bought them and they work really well. I would like to suggest that you try the Enacom AC filters and see what you think. It's a small investment compared to the QV2, and miniscule investment compared to a QX4.

Thats helpful Chuck. In as far as I understand what Quantum is about, I thought it was'nt to do with cleaning the mains. If it is I have a good power regenerator the Pure Power APS 1050 to do that and I would'nt need a QX4. Therefore I am not sure that the Enacom AC filters would be a help. I hope the QV2 does something of what the QX4 does. I see the thread you referred to, someone is about to add a QV2 to a QX4, I hope he will report back.

David,

I was under the impression that the QX4 did clean the mains, but I may well be wrong about that.

I had a really good conditioner and the QX4, and bought an isolation transformer that did more for my system than those two pieces. I sold the conditioner and the QX4 and went happily about my business.

Since you have a Pure Power APS 1050, I'd try to borrow a QX4 and a QV2 and try them one at a time to see if they do help and are worth the price. You hate spending $2,500.00 and finding out that it doesn't do what you thought or that your Pure Power is taking care of everything.

The Pure Power pieces are supposed to be really good!
