Upgrade...Sounds great...Goes away

the placebo affect is alive and well. if you expect to hear a difference, you are more likely to hear one , even if there is no difference in the components of a stereo system.

if you change a component and your expectations are that you will hear no difference, you may hear a small difference or none at all.

remember, a (small) difference that makes no difference is no difference.

it's mind over matter--if you don't mind it doesn't matter.

audiogon forums are good examples of group think. many members will believe opinions and recommendations without thinking for themselves. when someone suggests that is not a good idea, he gets critocozed for it.

i guess political correctness applies to the world of audio as it does in other areas.
