CDP - running only one channel, can this damage?

That would be fine.

Personally, i wouldn't do this. If you want to do this and keep both me and your gear happy, i would suggest using a "dummy load" or "resistive shunt" on the unused channel. If your Wadia has RCA outputs as well as XLR's, the simplest way to do this would be to place a resistor across a cheap RCA and be done with it. So long as you use something over 10,000 ohms, you should be fine. The parts will cost you less than $5 at Radio Shack.

As a side note, one can "break in" line level gear like this too. By using "dummy loads", you can put in a disc and let it play on repeat for as long as you like. No harm to the gear and no noise in the background while you enjoy your main components. Sean

PS... DO NOT try this with power amp outputs unless you are certain that you have resistors that are MORE than capable of handling both the power and heat dissipation.

Sean, I would like to hear your reasoning on this. What harm can possibly come from running a line level device unterminated?

Thanks for your replies. I need to run out for the day, but will check back in later. Thanks, Jim

Signal is still being passed and amplified without the proper load terminations. The amplitude of signals is reduced due to the lack of current flow, but that doesn't mean that the devices aren't sustaining some type of wear and or damage.

Try taking an amplifier and running it with no load with rated input. Theoretically, there is no voltage or current flow due to the infinitely high impedance it sees as a load, so there should be no problems. Wait a while and see what happens. While you might say that this is not a fair comparison, it is. It's just that the results that occur are far more visible / easier to measure with the amplifier. The same results / circuit degradation is taking place in the line level gear, it just isn't as evident or abrupt. Kind of like a slow and punishing life rather than a more timely death. Sean
