volume. At a higher volume setting of the preamp I get a hiss like an
untuned FM radio. Any suggestions?

To much system gain maybe ?
Use attenuators on the Touch and maybe on the power amp to .
Or DIY attenuators are really just l-pads cost you virtaully nothing if
you have a bunch of resistors .

Do you get the hiss if you disconnect the RCA interconnects from the
Touch to the preamp? Do you get the hiss if you connect another line
source (tuner, CD player, etc.) to the preamp? If you get the same hiss
from other sources or with no input then the noise is probably
originating in the
Could not see any sensitivity spec on the power amp thou .
The preamp looks nice with adjustable gain so use that if you can .
If gain could be adjusted directly that's actually better than
attenuators .
If it indeed is not another kind of proplem (like msstl suggested try
another source or no
