25 Watt Tube Amp for 90db Speakers?



They are Snell type J's that are 8ohm and 90db efficient.
Is a 25 watt tube amp enough? I am looking at a Cary Audio Super Amp. Thanks for any info.....

Not all 25 watt amplifiers are created equal. To me watt ratings on amplifiers is a lot like horsepower ratings for cars.
We're talking about Snell Js, a two way speaker with an 8" woofer. Regardless of the amplifier it is not a loudspeaker capable of reproducing orchestral peaks, cannonshots or Saturn V lift offs. With a 25 watt amplifier it should be able to generate 99dB levels at a moderate listening distance. That's not deafening, but it's plenty loud.
Rrog, 1horsepower = approx 745 Watts. Watts, units of power are all created equal: White watts, Black and Hispanic watts, Asian watts, tube and solid-state watts.

I agree with Rrog. I am newer to tube amps but my 6 watt SET amp with large transformers drives my 91db 8ohm paradigms pretty well. There are more factors to consider other than watts..
