Tube amp Low end Bass question


I use a Subwoofer with my current system (Rogue tube preamp -2nd pre out to sub, Nuforce STA200, Zu omen defs). I listen to EVERYTHING (Rock, metal, jazz, classical, bluegrass, electro/dance, etc) and love things a bit bass heavy. Now, I also love the 3d effect of tubes for the mids (especially classic jazz recordings). I was thinking I could pair up a Tube amp like an MC275 or something similar add a second SUB and adjust accordingly. 

Is anyone doing this with great effect?

I really like to crank it sometimes, I am a little hesitant that 15-20 tube watts may not be enough with the ZU's. My current SS amp is 80 watts and it does not peter out and feels there's plenty left. That is why I was thinking the 75 watt 275 may be the trick. 

Is the Quicksilver 60 Watt Monos SET?

You could consider trying a SET from one of the retailers who offer it with a generous return policy. If it is inadequate, return it. Usually you are risking $75 in shipping charges.

I doubt a 300B SET will deliver enough power but an 845, 211, or maybe an EL34 will give you enough power.  

As a fall back, he MC275 is a nice amp. 5w less in power will have no impact on your headroom with those speakers. The Zu Omens are really easy to drive. The issue is, if you don’t like it you are usually risking a 20% restocking fee. At least that is what the retailers I have asked will charge me.
Any SETs you suggest trying out? Isn't there such thing as a large watt set? I know Decware has a 40 watt stereo amp.
