The 965BX is at least 10 years old. DAC technology has most definitely
and measurably improved in this time, not to mention any degredation
caused by aging components in a player of that age. Audible
differences? To my ears, there was no doubt of audible differences
between players even back then. There were stark differences between
965BX variants even (the LE and the other one that came later, forget
the name..) My findings on auditioning these variants were consistent
with reviews I read later. Upgrading to an Arcam 5+ in my case
resulted in a more prodigious bass that made my windows rattle. No
placebo effect.

You are talking out of your reflex port.

The one area in which there has been no improvement ever in
CD players is in the bass response.

What you heard was an increase in overall level.

Thanks for the test music suggestion.
I'm sure I have a copy of MLITBOG somewhere.
