The office was closed today because of the midwest blizzard which gave
me some time to play. I decided to haul up a couple of Polk LSi 9's
from the basement HT to see how the Touch would work as a preamp
directly into an Emotiva XPA-2. It worked very well. The Polks are
rated at 88db sensitivity
At least compare with Touch :-/ Tube magic *shiver* .
Directly driving the power amp possibly via good attenuators such as
endlers.
But looking at the specs I see that it has an analog input ! very good
and the tube out can be bypassed too as it has an normal output, very
very good.
So you can
I'd have gone for a Transporter, using the balanced outputs to feed the
Emotiva XPA-2.

Thanks for all the advice. I finally decided on this DAC/Pre-amp:

It gives choice of tube or solid state output. I has no remote but is
small enough that I can just set it under the the Touch. Best of it
costs less than $250 shipped to the US.

By all accounts on this board and others, the Touch's DAC is decent
enough that most people can't distinguish its output from a much more
expensive dedicated DAC.
No, I don't think that's generally

The Touch has line-outs. Not the same as a pre-out. I think it's
designed to be an input to a preamp line-in. I think you could have
issues driving a power amp directly - among them the danger of blowing
out your speakers.
How so? Line out with a volume control is
If you want to use the Touch's analog out to feed an audiophile setup,
you may be interested in reading 'this thread'

Whether it will feed your amp too quietly (or too loudly) I can't
answer. Depends on your amp, I suppose.

Thanks for the great advice. Does anyone know how many volts the Touch
puts out at 100% volume? I can't find that specification anywhere.
