Amp, fully balanced, with sub via speaker inputs

I have been running Sunfire 12" subs, most recent model, via speaker level inputs from a class D amp, PS Audio G-250, not the integrated, just the power amp. I like it and was thinking of going to the Wyred 1000 series. I asked Wyred and they stated that using the speaker level inputs from a class D amp may damage the amp and the sub. My question is...Does anyone here run a sub via speaker level inputs with a WYRED 4 Sound amp? any problems? Thank you

Not sure how the Sunfire speaker connections work, but people have had problems with REL subs and class D amps. I think REL has come up with a cable that solves the problem, but their subs also use what may be a unique connector rather than speaker posts for the high level input.

I'd also recommend contacting Sunfire if you haven't already.

And lastly, any particular reason you chose to run speaker level rather than RCA or XLR to the sub? I know that speaker level is what REL recommends but not sure if other manufacturers regard it as preferable or not.
