Based on used prices (45 cents/dollar) I'd say full range speakers at 8K; amps at 5K; preamp at 5K; cables at 1K; CD at 6K; TT at 3K. So for about 35K in my estimation you have a high quality reference set up with preferences in intonation/timbre/presentation rather than weaknesses...
Law of Diminishing Returns; where does it kick in?
I think that most of us who have been in this hobby for a while have experienced the "law of diminishing returns", the point at which spending a lot more money produces a little bit better sound or just tradeoffs.
I would like your opinions on where you believe this occurs in Speakers, Amps, CD players, and cabling.
