3 watts of pure class A is enough for efficient speakers.

I'm sorry, but I find that hard to believe Basite. You must be listening at whisper quiet levels if you are just using 0.2 of a watt per channel. Your speaker specs are; 87db at 1watt/1mtr, and mfrs generally tend to overstate efficiency. Perhaps you should check your power metres. I can assure you that you are using more than 0.2 of a watt for an 87db speaker at reasonable listening levels. My speakers are much more efficient than yours, and require considerably more amplifier power than you suggest. For 3watts to be sufficient power for a speaker, that speaker would have to be VERY efficient, such as the fostex/lowther type driver Bernd has in his office system, on the order of 95db @8ohms or more. Even though 3 watts will run a speaker system of average efficiency, say 90db @4ohms, much more power will be required to accurately reproduce a recording with wide dynamic range without distortion or colouration.
