Balanced XLRs to cable RCAs

Does your amp have a balanced/unbalanced switch?

Is the pin configuration correct & do both cables match?

Is there any difference in the materials between the RCA & XLR?

Driver-

no balanced switch on amp

cables are same 3 ft length, XLR from monoprice?, not expensive, but well reviewed by users, 100%
first XLRS Ive tried.

the RCAs seem same heavy duty, quality gold plated const., better than others inc. monster.

AMP, PRE, pin config is 1 grnd, 2 hot, 3 neg., not sure what cable config is? are some different, how would you tell this?

thanks,
rms

Maybe you need to let these new cables break in. Signal Cable recommends at least 70 hours of break in time, and I can confirm that after this amount of time, they did sound much better.
