Tube amp with Sierra-1 speakers?

[BBest]

Howdy all,
I have a 20 watt-per-channel tube amp and I'm wondering if anybody has had success driving Ascend Sierra-1s with a tube amp of similar power. If it matters, the amp is an Ideal Innovations Elite80. The room is 14x15. I know that I can calculate the volume level based on the 87db efficiency of the speakers, but there can be a difference between good volume level and good sound.

I guess I'd just like to hear any experiences or opinions on this possible pairing.

Thanks,

-Blake

I've driven my Sierra's with a 2 watt amplifier, with good results. Granted I couldn't turn it up too loud before clipping, but it sounded great. 20 watts will be more than enough in a 14x15 room. I doubt that even "shouting at the guy next to you" levels the amp would be peaking at more than 10 watts.
