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

Mauidj, PurePower 2000 is superb; it added clarity, cleanliness and dynamics to my system and provides constant 120V/60Hz power. I bought it from Brent Rainwater at rainwateraudio.com. Brent can answer your question better than I can. Also purepoweraps.com website is very informative.

I second that, it isolates you from the mains via a battery, creating a clean mains source. I have'nt tried many power conditioners, only the Kemp power source before. I am really impressed at what the 1050 has done for my system, I've been using it for 3 years now.

The company will advise on the capacity you need from their regenerator. I have the 1050, John the 2000. I have seen it said that whatever power you may need the 2000 is a better unit, with better results, but I can't confirm that. For the price, I think it is a very good deal.

Getting back to the differences between devices, Doug reported differences are minimal, that is helpful, but has anyone done an A/B comparison between them. The answer is probably not, but I'd like to hear if anyone has.

Well I found a QX4 second hand. They don't appear too often, which says something about whether they work. Well it certainly seems to, with greater clarity and a bigger soundstage.
I still don't think they are worth the full retail cost.

I was being facetious, but I'm not surprised at your conclusion.
