Just give it a try:
Put a potmeter inline L and R channel and turn them until you find the noise
acceptable.
Sort of like the "passive volume controls" you can find:

If you find the appopriate resistance put that as a fixed resistor inline in
the left and right channel.
Theoratically you now have an impedance mismatch but it has allways worked
for me.
The scansound product helps-no hiss any more!!!!
