<p>It was...I saw a third 363 on Reverb and bought it so I now have
three pairs of CAT 300 SR/A cards, but didn't need them, but I
wasn't certain all four of mine work 100%. I do have a fourth 363
with SR-only cards. The Dolby A decoders seemed to be OK from
quick testing (I don't have a working version of the tester, and
besides, that's for CAT22s). I no longer trust the Cat 22s and 361
frames as the 363s seem to sound a bit better, but the big
improvement is on the SR side between the Cat 280 and the Cat
300...and I hear (but haven't evaluated) that the SR only cards
sound better than the SR/A cards.<br>
</p>
<p>Anyway, the 185 nWb/m cal tape was most useful and I confirmed
the level against a modern MRL 250 nWb tape.</p>
<p>If everyone completely and diligently follows the rules, the cal
tones are unnecessary. <br>
</p>
<p>Speaking of this, the world needs software decoders for Dolby A,
S, and SR. It seems as if we have workable decoders for Dolby B
and C, dbx I and II, and Telcom C4. I have not tested, but the
same folks who brought us the Telcom C4 decoder are working on
Telefunken High-Com, Nakamichi High-Com II, and CBS CX (both
versions). These three are subsets of the Telcom C4 pro system.<br>
