I found a vintage sansui g5700 75wpc about 2 mos ago $20. $10 for cleaner for tuner and knobs . swapped out my 40 wpc kenwood for this. so far so good.
With the m80's on the way I 'm debating what to do first.
1. hook them up to the sansui in the living room ( dinner music)
2.hook them up thru the speaker selector to the adcom 555 amp right next to my hpms and do a/b comparison.
Also picked up another 40+ used cds today. (gotta love princeton record exchange.)
