Thanks guys...I think? Sorry if some of you may have
thought I was questioning SACD...I'm not. Both SACD and
DVD-A have real merit. The question was talking about
the 1-bit type of D/A and the use of OP-AMPS rather than
discrete components for the audio section. When Sony made
the XA-7ES they were very verbal about the Class A discrete
FET audio section...and now all of their units are using
OP-AMPS. I don't recall there being people offering
mods for the XA-7ES..and now there are several people
offering mods for the Sony SACD units. I have stated this
is threads before..that if OP-AMPS were so great..shouldn't
ARC, Conrad Johnson, Krell, Levinson...etc be using these
"great" OP-AMPS in their pre-amps? The reason people are
doing these mods..is that the audio section of these units
are not where they should be. Nothing wrong with OP-AMPS in
and entry level SACD changer...but in the $5000.00 reference
unit?
So.....what I was questioning was the 1-bit/redbook side of
these players...where most high-end units have gone to 24/96
upsampling...and the audio section being OP-AMPS...and
OP-AMPS generally not being thought of as "State-of-the-Art"
for audio amplification.
