Musical Fidelity and Jolida both make giant killer amplifiers. My friend bought a Nu Vista on audiogon for $2300....it comes with a power condiotioner about as large as the amp and has incredible power, detail and musicality.
I owned an MF A3 integrated (wonderful little amp), which led me to a A3cr power amp (which stereo times reviewed as better than the NU Vista at only $1,400 new compared to $5,000 for the Nu Vista integrated or seperates), I paid $650 used for that, and coupled that with the new Jolida Fusion preamp that I bought for $950 new in September 2011(which Wally of Underwood HiFi rated higher than the very well reviewed Jolida Envoy at $1,500)....so for $$1,600 I have a pre/power combo than sounds better than $5,000 Cary and McCormack seperates I've spent several hours listening to when auditioning speakers. I've owned Conrad Johnson and Classe' components before (both were great) and this just blows them away.
I've heard the new Wyred4Sound 300 watt integrated is absolutely incredible for about $2,000, but I haven't heard that one.
