ACH! As you point out, some evidently will do better. I am finally
moved to get off my duff and check the manuals for my current auto
units. The Sony XR-5500 in the Audi claims 40-16Khz response for tape
and 58 dB signal to noise for type II and IV tapes. The FM tuner is
rated 30-15Khz, which is what I must have recalled when I flashed
back on the specs.
The slightly higher-zoot JVC KS-RG4 in my Datsun Z-car (with 6-disc
changer) claims 40-16Khz response with normal tape, 40-18Khz response
with Metal or CrO2 tapes!! Also claims 40-15Khz for FM reception,
and 40-20Khz response for the amplifier section, which I will grandly
and with no justification assume is how it treats the CD input. I
believe it does give more top end response on CD, because on some CDs
I actually end up turning down the treble slightly.
SO - YES, I was wrong again! I still wonder whether the Hon Dave
head is actually getting 20K out of his Nak, but I'm not there to
Please note that the astute Alexi says *recorded on the same deck*.
Tapes are prone to performing best when recorded and played bacl on
the same unit. Alexi, will that tape play back the 17 khz signal on
your car deck?? I wager that many tapes recorded on top-end
equipment are not reproduced as well by the car deck.
And of course, if one listens to Factory recorded tapes, this is all
moot - since the tape stock they are recorded on is egregiously cheap
and not fit to reproduce music at all.
Live and learn, folks. Thanks for correcting me - I am now better
informed about the frequency response issue.
PS, Dave: I have a 1982-vintage 3-motor BIC home cassette deck, which
is not available any more. It does pretty darn nice work, too!
