I used to love vintage amps and receivers but as of buying my Nad 705 made in '92 I think I've started to realize that modern amps seem to just sound better, to me atleast. I'm looking for something with a clear or "Cold" sound, I tend to favor amplifiers that can make things like drums and cymbals sound realistic and pronounced. I've been looking at the Yamaha A-S501 and the Marantz PM6006. I'm concerned about the Yammie because from what I've read it "lacks composure" and the Marantz "Sounds smooth". Some insight would be very helpful. Thanks!
