I've been away for the Xmas break, and have just noticed this thread.
Since it seems that it was started in response to a comment I made in
another thread, I should try to clarify what I meant.

What are some working numbers here? For example, many amplifiers --
most? -- have 10-20kOhms of input impedance. Some switching amplifiers
are higher, and some other amps are higher yet (I think Cary's solid
state amp is around 100 kOhms, but don't quote me on that).
So, is 20kOhm enough not
Some power amps prefer an active pre-amp in front of them and some don't
care...you need to find what works in your system. There is NO rule that
says passive level control always sounds better than active...it doesn't
work that way.

Sorry you are correct - it was a typo. 100x it is.

Never said it did. Personally, I strongly prefer the use of a preamp
in my system.

I agree with all of these posts, in that, what sounds good to the
listener is best.
However, the original quote said that no pre-amp is best.
But, if the Transporter does not have a pre-amp how can it drive my
power amp? It must have a pre-amp (but no pre-amp is good, according to
CliveB).

hi ModelCitizen,
The Transporter's unbalanced analogue output puts out 2Vrms which is
enough to drive any of my amps without a pre-amp.
Historically, the job of a preamp was to boost the signal from phono or
tape deck inputs up to the required voltage for an amp.
Also, some input signals needed

Except for the old LP/Phono sources, which are extremely low in level,
requiring step-up preamp stages, most modern music sources, ie CD, DVD,
Tuners and yes, even Ipods, provide higher output voltages (around 2V),
enough to drive many amps into overload. How can you be
