Does anyone know if it is possible to use the phono pre-amp ground input to ground an external sub when using high frequency connection? on the AMP.

This sounds at best unwise -- potentially injecting hum -- and at worst dangerous to the integrity of the Amp. What exactly are you trying to achieve? A high-level connection to the REL?


What is the ground on your phono preamp hooked to? Likely better to use that for the sub too.
