What numbers are important in SS amps specs

WATTS are multiple of current AND voltage or a physical ability to do the WORK per unit of TIME(Joules per second).

Where's the solid state WATTS?

WATTS are important and so is important a condition under which these watts had been measured. Hence the most important spec you should pay attention for is sufficient number of CONTINUOUS WATTS i.e. continuous power which is likely neccessary to drive your speakers.

Then knowing the possible range of your speaker impedances you should verify if the amplifier will be able to handle the peak speaker loads.

Such specs as THD, peak power, S/N are now pointless...

And finally, WATTS are for all WATTs.

The spec wars are over. Numbers, even power ratings (wpc)can be completely deceiving. There seems to be many factors that come into play that determmine how well an amp will drive a speaker. Ask about the experiences of others with specific combinations. The only real way to know is advice from those who you trust and first hand listening.
I seemed to get the best results from my Totem Ones with the most powerful amp I tried. My friend who has them now gets great sound with his Bedini 25/25.

I would posit that the weight of the amp divided by the output power in watts, higher being better, comes closest, though still not close, to determining the sound quality of an amp. Seems that pounds per watt is as good as any other guage.

Viridian - you forgot to factor in the number of fins, thickness of faceplate, and finally multiply that all by the number of blue LED's on the unit. Doing this will give you the THI or 'Total Hype Index'.

Marty, my amp weighs in at: 0.266666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666… pounds per watt. Is that a good rating, and how might I make improvements to avoid that annoying repeating decimal?!
