Well, I'm discovering this forum a little late but here is my "amp evolution":
1987: NAD 7220PE Receiver(my first component system which also consisted of a Dual 505-2 turntable and Boston Acoustics A40 speakers)
1999: NAD C740 Receiver. Bump up in power and sound quality. At this point also had NAD 502 CD Player and 614 Dual cassette deck)
2012: Rega Brio-R. By far the best bump-up in sound quality. Much more depth, detail and clarity with the Rega. But note this is also coupled with a prior upgrade to the Rega Apollo CD player and Rega P2 turntable (bias-2 cartridge). The Brio-R is bringing alive all of the detail that my P2 and Apollo is capturing.
