If you have been conditioned to how your modest system sounds on a particular track/LP then you may indeed be disappointed by a meagbuck system that does it correctly. Many people have excessive muddy but impressive bass and pleasant but recessed midrange -over time and continued exposure this becomes "normal" and "correct" to their ears/brain. PLay a track correctly and they have been so conditioned as to feel that it is wrong or inferior.

So I was down at the local hifi dealer, its been a while, and I decided to listen to a LP in the store that I heard many many times on my own system and you know what my modest system relatively speaking, sounded similar if not better then the mega show room system with the 10k arm and the 30k preamp and 50k speakers. I was in disbelif. In my opinion there is not need to spend buckets of money to achieve the last 5 or 10%. Of this this is bad news for hifi dealers but I suspect they realize this too.
