http://wiki.slimdevices.com/index.php/DIY_passive_attenuation http://wiki.slimdevices.com/index.php/Digital_Volume_Control_and_SNR Touch uses an 24bit digital volume. The thing is that you should use passive attenuators before the amp so that you use the Touch at decent levels or if you have a power amp where you can adjust input sensitivity. You should try to make it so that 100% volume on the Touch is as loud as you wanna go but -not- louder, you should be able to use that volume that means that ~70% is normal level . You don't want level mismatch so that you use volume at 10-20 ,. The SNR of the Touch would not be fabulous there. Touch outputs circa 2V rms , so it should be able to drive most power amps. Read you power amps manual regarding input sensitivity. Also the attenuators would protect you if you by mistake play at very high volume or a bug put's the volume to 100% . The player could have other bugs too outputting strange noises or something, but I've never heard of one with the Touch . The old ip3k players has a rare bug when they can output very loud noise that sounds horrible, but that bug is very rare. I use these attenuators, they damp -10dB if thats to much consider DIY . These thing are 2 resistor so they don't affect sound quality at all . http://www.rothwellaudioproducts.co.uk/html/attenuators.html Other people wants adjustable attenuators for example endlers . This is a more flexible solution. But can cost more as you want a good quality switch in theese (so it does not corrode and cause contact problems ) I have not tied the endlesrs but they come higly recomended by other here on the forum . http://mysite.verizon.net/vze4c5pt/ -- Mnyb -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH and assorted amps SiriuS, Classe' Primare and Dynadio speakers, Contour 4 Contour Center, and Contour 1.3SE rear ch.
