I.e play album XXX and track YYY and if music AAA sounds like BBB there's jitter otherwhise if it sounds like CCC there isn't.
I do not have any dedicated stereo gear, and I have been looking at some possibilities for music improvement. My current situation is a Denon 2307 AVR and B&W 603S3 fronts and LCR60 centre and I must say I am very happy with the sound for both HT and music. At the moment I am using a DVD player for CDs because my old CD player has decided to go into retirement. I am considering purchasing a new CD player but I am not convinced it will make much of a difference, and perhaps I will be better off spending the money on buying some more CDs.
I am inclined to agree with Terry. Once you get your speakers right, most other improvements tend to be more marginal if not outright insignificant given the spend involved. Sometimes the improvements must be so marginal that a change in room temperature would probably have a more profound effect.
PS: I am a rank amatuer who only upgrades his system 1 in 20 years, so I hope I haven't offended anyone.
Anyway, all the brotherly love in this thread has inspired me to put on some good 'ol 60's music. Hmmmm, lets see, what have we got here..... how 'bout Hair - Original broadway cast? (may as well, because I don't have much on my head!).
