Thanks for advice on smooth amp!

I wanted to thank everyone who checked in with their opinions on what I should do to smooth my system out. I realize that there is much more to think about than just the amp! Unfortunately being on a grad student's budget severely limits my ability to make changes (and I failed to mention my budget limits in my previous post). That being said, I may consider trying out a new CD-only front end, as this, ostensibly, is the weak link in my system. Perhaps a new player, as DAC's tend to be more expensive I think. We shall see... Again, thanks to everyone for helping me out! djjp
