Female XLR to RCA?


In a solid state analog system, Is using a connection cable with an XLR Female to an RCA male advisable? I'm interested in a preamp that is variable XLR output only  (both RCA outputs are fixed) Of course my power amp is RCA input only.
Thanks.

Juan, correct me if I’m wrong, but as long as the impedance of the amps input is at least ten times higher then that of the preamp it should work.  Right? 

You'll only get an advantage if your amp/preamp are differentially balanced.

XLR is really for Pro use with long runs, prevents interference to signals.

One advantage of XLR in short runs in home systems is that it is a LOCKING connection, whereas RCA connectors can be problematic, even sporadically problematic. Lot of cables, mess with this cable, it disrupts that cable.

There's nothing magic about an XLR connector. Their advantage in long runs is only when they're used in balanced circuits. It's not uncommon to see XLR connectors used in a conventional unbalanced circuit.

Some XLR connectors lock (most do), some don't. Some RCA connectors lock (most don't), some do.
