Having heard the Quantum at RMAF and the Roy Gregory Demo at heathrow last year, I was mightily impressed. The latter demo was clear they are not an alternative to a good condition, I use a Pure Power APS. At the Gregory Demo, it was the Quantum seemed at least as impressive as changing to the Stillpoint stand and supports under the speakers, at less than half the price.
Being cheap, I will continue to look for a second hand Q4
