Al,
You wrote "That model would be located close to the amp, and connected to the amp via what must be a short XLR cable, and connected to the preamp with whatever length of RCA cable is required."
I have a pair of P1-XR ISOMAX units I've used to convert the XLR of an 18' cable from the processor to short RCA cable to a KEF KUBE near Proceed amps. My reasoning is to use XLR for the long cable run. Have I got that backward? The ISOMAXs removed an audible buzz encountered with a simple adapter. If I have it backward, then I'll just use RCA cables from processor to KUBE to amps.
