Nu Vista M3 Intergrated WHAT A DIFFERENCE! I paid MF for an upgrade over 10 years ago; I’m sure I didn’t get my own amp back, and the amp I got back didn’t sound any different. The amp recently had a fault dropping the right channel intermittently. I called John who immediately stated the selector switch was the culprit which gave me confidence, so I went for repair and upgrade. Bloody hells bells; after a few days burn in I still have the MF NU VISTA sound, but with more clarity; and where did that extra bass come from? As John said when I collected “it’s all the amp You’ll ever need”. Must get the Nu Vista CD done next. Thanks John I’m very impressed.
