Instead of buying fabulous pre-amplifiers/acoustic diffusors/special cables/... I long prefer to attend and spend my money on LIVE classical music concerts.
BTW, I discovered that many audiophoolers own only 10 or 20 reference records and listen only to them.
Maybe my several thousands CDs collection (bad recorded/with no dynamics/uncrystal clear sound/whatever negative thing you want) will be no par to their records but nonetheless I'm enjoying it!!!
