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.

The amplifier power will also depend on the room size, and your listning position distance from the speakers.

I use a PrimaLuna Prologue 2 ( 45 Watts KT-88 Valve Integrated, close to US $ 1K ).

Speakers are Sonus Fabor Extremas. Same sensitivity as your speakers.

Room size is approx 30 feet x 15 feet x 12 feet height.

Speakers & listning position is accross the width ( 15 feet ) of the room, not the length.

My listning position is approx 10 feet from the speakers.

I get good volume ( my gusstimate is 103 dB ) before the the amp runs out of steam.

I would HIGHLY recommend the PrimaLuna Prologue-2 if you listen to Rock and Jazz. The Prologue 1 with EL-34 valves is probably better for classical.

Hope this helps.

Cheers
