With our stuff you likely will run into a buzz problem since the output of our amps is balanced (neither side is at ground). But you won't hurt the amp.

I prefer to run a second output from the preamp to the subwoofer.

I run 2 REL T9i subwoofers in stereo, one subwoofer with one M60, in high level input (speaker output level) balanced mode.

Completely quiet.

Quite happy with the additional bass. Speakers are QUAD 989 or KEF LS50, Zero-former at 3X.

I doubt very much my Transcendent OTL is balanced, but if I hear a hum I now have a clue as to possible reason, so thank you!
