I've using a Marantz SR7001 amp for music & movie duties for a few years and it's been pretty good but I decided to dig out my old Cyrus Straight Line amp, Sony CDP715E cd player and Dynaudio Audience 42 speakers and WOW! the difference is amazing! The only problem is that the Cyrus is knackered - Only the CD and tape monitor works and I'm looking for a replacement as it's on it's last legs. I prefer buying pre owned as you can better value and been looking at the Marantz PM7200, PM-66SE KI, Pioneer A-400 and A-A6. I'm looking to spend around £200-250. I tend to listen to stuff like Pat Metheny, Steely Dan, Chromatics, The Crusaders, James Brown and Kraftwerk. Any advice would be greatly apprieciated.
