Amps for Maxx 2's


My audiphile friends are certain that my 140W Yamaha receiver will NOT do it w/ the Wilsons. Looking used. Recommendations for amp, pre-amp, source? Thanks

Really, Really... come on you got to be kidding Maxx 2 are like $45K speakers, with a Yamaha receiver??? This is a joke right?
The only Yamaha amp and preamp i would play on the Maxx 2's are the Yamaha MX-10000 amp and CX-10000 Centennial series. Those were world class in the late 80s.
Edseal, I'm in kind of a similar situation.
I'm using Levison 33 amps, Levinson 32 preamp on
Bose 901 speakers. LMAO
Pass Labs XA-100.5 Pure Class A monoblocks. 200 watt's into a 4 ohm load. They drive my Watt/Puppy 8's as loud as I would want w/o breaking a sweat. Solid class A sound with a firm grip on the bass unlike tube power amps.
