As you well know Scott, Steve Hoffman is the mastering engineer of
all the AF SACDs and he has said on his website that he uses a *split
feed* coming out of the mastering console which feeds *two* different
A/D converters. So, as Steven Sullivan so succinctly put it, "A
mastering chain that bifurcates at the A/D stage is no longer the
same chain." Any comparisons between the two layers have to take this
into account and it then becomes quite difficult to pin the
differences down to the individual formats.

Where did Steve Hoffman say this?


Here in a discussion concerning the mastering of his Creedence SACDs:

In the same thread, when preaching to his flock, he comes out with this
statement regarding the benefits of hi-res:

IOW: more points = more accuracy.

Here is the whole thread (WARNING: It contains a lot of audiophile
techno-babble and a bunch of ignorant people thanking each other). BTW, I am
the thomh in this thread whose ass was banned for causing too much trouble
and not following the party line. Steve Hoffman enters the discussions on
page 9.

The conclusion to all of these tests have been consistent:

When level-matched, *no one* has yet been able to reliably tell the
original from the copy.

Obviously, your system lacks resolution. ;-)


Yeah, and I have been told by Steve Hoffman that my ears are probably not up
to the job as well. So what is a middle-aged man to do?

Seriously though, nice job!


It was quite fun. Some of the audiophiles came back for a second test but
this time armed with their own *very* expensive interconnects. No
difference.

I have heard audiophiles talk about the "day and night" differences
between Redbook and SACD/DVD-A but they simply do not manifest
themselves on my equipment and the ears that have listened.

Good show, but nothing new. Over 20 years ago we did level-matched,
time-synched listening tests where we took the output of a high end 2
track
high speed analog tape deck, and sent it through either a short piece of
wire, or a pair of good-quality converters back-to-back.

More details:

No audible differences were found.

And this was 20 years ago? Good to see that digital was pretty mature even
then. I have heard others that have done similar listening tests with the
same outcome.

BTW, I got the LynxTwo based on your enthusiastic endorsements and
evaluation. It has served me quite well.
