tube watts vs transistor watts?


I have always been told your loudspeaker does not need as many tube watts as transistor watts. Why? If the loudspeaker manufacturer says it takes 200 watts for power handling how many tube watts does it take?

@Almarg,

Thank you for your technical reponses. You inquired about the Octave amplifiers and you were looking for more information about these amps. I would like to hear your technical response about the methodology employed by Octave for their amplification. I am also a Octave amplifier owner, MRE 130's, and as was stated by another new owner, the bass is incredible. My mono amps sound more powerful compared to SS amps rated higher in wattage. I drive a pair of B&W Nautilus 800's with essentially no problems, and bass loss is only at the very lowest bottom end of the spectrum when compared to a powerful SS amp, but for the majority of music, sometimes I feel as if the bass is comparable to SS Amps with a sub in the system.

These links provide you the information you were asking for regarding the output and THD ratings of both the Octave V70SE and MRE 130's amps. I am wondering on what you think about the use of the Super Black Box to allow more current overhead for the AC delivery.

In one of the German tests, they were using a pair of Nautilus 801's that they claimed never sounded as good until the hooked up the MRE 130's. That is why I have been standing up for the N800's with tubes, the Octave MRE 130's drive these speakers easily and the with the addition of the Super Black Box, adds more capacitance to the power delivery allowing speaker loads down to 2 ohms to be driven easily.

For the masses, I think the explanations on how such a methodology or topology employed succesfully to drive low impedance speakers based on tube technology compares to SS designs.
