Are Sony SACD Machine Owners Crazy??


I am sorry about the "tabloid" title..but another
post I did got little response on what, I think, is a real
question. Ie:.. many people have stated that the playback
of standard format cd's (16/44) on these SACD machines is
very good...indeed beyond things like Levinson..etc. The
question is ..in this age of "upsampling" 24/96..and beyond, how can these one bit/bit-stream (in "redbook" format) units
be so good? This is asking the owners of the model 1, 777,
9000..etc. Sony players..how can this be so. I had owned
the Xa-7es at one time, and thought that the excellent
playback was the FET analog stage...these new SACD machines
are all using OP-AMPS....not very "high-end". The concern
I have is that while we all hope for a format that will give
us analog sound in a digital format, the near-term concern
is what any unit...SCAD or DVD-A will do with my collection
of standard CD's?

According to Robert Harley in isssue 120 of The Absolute Sound the SCD-1 and 777ES DO NOT use op-amps.

To quote RH directly:
"Commendably, the analog output stage is an all-discrete design(no op-amps)."
Issue 120, p. 36.
An additional quote may help clear up some misconceptions:

"Two transformers supply power to the unit, one for the analog circuits, one for everything else. The SCD-1 has more power supply regulation than I've seen in a Japanese product, and even uses discrete regulation rather than IC regulators. Moreover, the analog output stage has additional on-board discrete regulation and power-supply filtering right next to the audio circuits. This a decidedly High End design technique"

"This is clearly an engineering-driven product designed to show the SACD format in its best light, not a product dictated by the marketing department. In fact. the SCD-1 is perhaps the tweakiest product I've seen from a large Japanese company."
