ARC Ref 75 SE Question

[Tie_breaker]

I recently purchased a used Ref 5 SE that I am very happy with. Currently I have Bryston 7B3 mono amps and PMC Fact 12s along with the Ref 5 SE in my system. I am quite happy with this combo. However I have never owned a tube amp before and am really pleased with the improvement in sound quality that my Ref 5 SE brought to my system. So I would like to try an ARC tube amp. I am looking at a Ref 75 SE to pair with the Ref 5 SE. I assume this combo will be great, however the PMC Fact 12s are power hungry with 84dB sensitivity. I am wondering if the Ref 75 SE would have challenges driving the Fact 12s. The volume is typically between 20-40 on my Ref 5 SE. Any comments would be much appreciated.
