Pre-amp + Integrated + Headphones
By M0nica L - usenet poster
I have a NAD S300 integrated amp which does not have a headphone socket.
Unfortunately most headphone amplifiers have seem to cost a few hundred
pounds so I was wondering could I use the tape monitor output from the S300
to feed a cheap 2nd hand pre-amp (probably NAD 118) and use the headphone
socket from the pre-amp. I realise that the headphone socket on the pre-amp
will be pretty low quality but since I won't using headphones regularly it
shouldn't be a problem.

If you want a cheap and cheerful solution (couple of quid) you could buy or
make an adapter to allow your headphones to be connected to the speaker
sockets.
If you want to make one, you just need to connect a couple of resistors in
series with the outputs of the amp to a suitable headphone socket; I would
suggest 150 Ohms, 2 Watt resistors. Has the amp got two switchable pairs of
speaker sockets? If so, and one outlet is unused at present, you could
leave the headphone adapter permanently wired in.
This approach would probably be lower quality than the one you mention, but
it is the way headphone sockets are wired internally on many integrated
amplifiers.

Gary,
This would certainly work, however much better results can be obtained using
a dedicated offboard headphone amplifier such as the
Creek OBH-11. Priced ??129
