How do tube Watts compare to SS Watts?


I have Theil 2.2 speakers, which have a low sensitivity (86dB), but I would like to get an intergrated tube amp. Or even all tube. But I don't know how many tube Watts I'll need to drive the Theils. My guesstimate is @ 50wpc for intergrated tube amps, but that could be wildly off. Are their mathematical conversion formulas? Second, if there is a rough range, might you be kind enough to suggest a few worthy candidates that, wheather new or pre-listened, are under $1,000 USD (e.g., Cayin model xxx). Thank you most kindly.

I had trouble driving CS2's with Quicksilver mono amps that were rated at 60 wpc. The room was about 12 x 20 and I thought I needed tubes to make the Thiel's sound smooth and sweet but when I switched to a smaller high current SS amp they were controlled, not sloppy.

Best advice I can give is try a tube amp with some guts and use the 4 ohm taps if it has them. Or get a SS that doubles into 4 ohms.
