Can I use both sets of analog outs on my CD player

Sure, I use the extra outputs from my Arcam 9 to a headphone amp. Seems like you've discovered a clever way to do a/b testing.

If both line level inputs that you'll be connecting to have been used equally, you should get equal results.

One of my friends was using a dvd player to listen to CD's. After taking his system apart, he switched the output of his DVD player into the input of his receiver labled "DVD". In the past, he had used the "CD" input.

When he started listening to the system again, he found that it sounded very different and not for the better. He then disconnected the DVD player from the DVD input on the receiver and hooked it back up to the CD input. The sound was back to normal. While he was skeptical of the results, further testing with my brother swapping the cables into the two different input jacks showed that there was a discernable difference.

The only thing that we can figure is that due to lack of signal flowing through the internal jacks and wiring, the sound was different due to a lack of break-in from extremely limited use. As such, i would verify that the player sounds the same between both inputs using one set of cables prior to counting on getting identical results. Sean

My only $.02 is to ask the higher minds here how the interconnects may impact each other.

IF the RCA jacks were wired in parallel wouldn't the capacitance of the cables be summed?... ARE the RCA outputs wired in parallel?... isn't capacitance -one of- or perhaps -the- biggest driving factor in interconnect design? What other reactive factors must be considered if these cables are effectively coupled electrically in some way?

When taking into consideration other factors that are cited on Agon as being detremental to sound, it seems like the effect of running these cables concurrently could have a large impact *relative* to some other seemingly minor tweaks.
