Tape out is often used in tthis application.

Headphone out is normally an attenuated signal from the power amp section and
hence won't be as clean as the preamp signal.

Neither are classic 'line level' connections per se - but are likely to be
close(ish) in terms of signal voltage.

Well, it's not line out as we know it Jim, but what the heck !

What is 'equalised for a headphone' ?

TAPE out is preferred - it's normally a fixed-level (1- or 2-volt
peak-to-peak) line level signal.

The HEADPHONE output is typically taken from the power amplifier
output, via a series resistor which lowers its amplitude. It's
affected by the setting of the volume, balance, bass and treble
controls, and its level would have to be manually adjusted to
line-level standards via a voltmeter.

So far, so good.

Second choice. Reason: Level goes up/down with receiver volume
control, affected by tone/"loudness" controls. Quite likely more noisy
because it is attenuated output from the power amp.

Prefect choice (for this situation, at least.)

"Tape Out" is preferred. Recording is obvously the intended
use of this output.

It will do in a pinch, but certainly to be avoided if you have a
real "Tape Out" available. There is typically no difference
between the headphone output and the speaker output except
some attenuation on the headphone output (to keep you from
hearing how noisy the power amp really is.) Headphone output
*may* be the same as line-level depending on many variables
most significantly, the setting of the volume control.

Huh? I thought everything, TAPE OUT, CD IN, TUNER, etc were all line
level signals except the phono input.

They are similar to pro 'line level' but not actually quite the same.

Usually rather lower voltage.

Yes they are all nominally *CONSUMER* line-level (-10dBu).
With the possible exception of the TAPE OUT, but likely not
enough difference to be of concern in the Real World(TM).
Perhaps that was the unstated assumption by Mr. Bear.

Which if a completely 'nuther subject. Not line-level (consumer
or pro), or mic-level (or EQ) either.

The pros sometimes run their Line Level is a bit hotter than the
domestic version :-)

This is probably sensible. Domestic equipment rarely comes equipped
with output and input trim controls. It's much safer to run outputs
a little low (and need to turn the power amp up a bit) than to run
them hot and risk overload.

For some reason, domestic CD players often have particularly hot Line
Outs. I wonder if the audiophile criticism of digital audio being
"harsh" is caused by a CD player overloading their "Line" input?

Indeed.

Trying to adapt pro standards to consumer gear is fraught with
difficulty.

As you are aware - consumer line level is indeed lower voltage than pro
but certainly within the range of compatability for practical purposes.

Much pro gear has -10dBV 'compatabilty' as a switched option or a gain
setting, although consumer line outs seem to vary hugely in reality,
especially now with low voltage operation of some portable devices. You
can always fix it with a gain trim anyway.

That was certainly the case in the early days of CD. Pre-CD, the
commonly accepted "line level" standard was 1 volt peak-to-peak. When
CDs came into use, CD player designs settled on a 2 volt peak-to-peak
full-scale standard.

There were some older pre-CD preamps and receivers which overloaded
and clopped pretty badly when fed a 2-volt signal, and some rather
nasty sound was the result.

This _should_ be a thing of the past, with modern designs... but it's
certainly possible that some newer designs are still overloading at
the higher CD voltages.
