From my experience, the tape head things sound really bad - no highs.
It probably depends on how well the heads align, but I would rather
listen to unequalized RIAA than the particular tape head thing I had.

Another option is to open the stereo, find the phono preamp, and
bypass it. In other words, connect the wires that go from the
selector switch to the output of the phono preamp directly to the
phono input connectors.

They vary quite a bit -- I've got a cheapie Goodmans one that's awful,
and a Sony one that works very well. I don't think I'd want to use one
on something other than a car stereo, though; even if the sound
quality's OK, you're going to have the cassette deck's motor running all
the time.

That'd be my preference, if the OP's reasonably comfortable with
electronics or can find somebody else who is. A few minutes' careful
poking around will probably find a couple of tracks that can be cut to
inject line-level audio at the output of the preamp; you could even add
a switch if you want to retain the phono input. But I'd imagine the OP
will be quite happy just using an attenuator and fiddling the tone
controls...

Another easy place to find is the top of the volume control, add
a changeover switch and series caps -- drawback is that you likely
lose the tone controls.

Yes, that was my contention. Everything that has been said about reverse
RIAA compensation etc is absolutely true, and yes, such a network is
reasonably easy to knock up, but I got the impression that, given that
you know that what you are doing is not ideal in the first place, but
the *only* way that you can do it, then it is just a QAD 'fix' that you
are looking for, and the simple two resistor potential divider network
will do that just fine. I am also sure that between the Winamp G.E. and
the tone controls on the stereo, you will be able to compensate
adequately (but not perfectly) for the non-linear frequency
characteristic of your phono input.
