Krell Amps vs others

My question relates to the powering of speakers that can handle large power loads. Krell is often mentioned as quite good at pushing these type of speakers (ie Dynaudio). What other companies make equally powerful class A amps wih high output into 4 Ohm speakers. My sense is that my Dynaudio Contour 3.3 can take a heavy power load, even more than the 450wpc into 4 ohms they are currently getting from y existing amp.

You may want to give the Plinius SA-250 mk IV a listen. 500 watts into 4 ohm, Class A. I personally would go for a used pair of the Threshold SA12e monoblocks, they will also put out 500 Class A watts into 4 ohms. The best high power Class A amps period, IMHO.

Be careful throwing around the "class A" terminology as nearly all amps that flaunt Class A status are only so for the first tens of Watts (even a hundred is rare), not for the full 500W or what. A 500W class A output would burn up 2500 to 3000W which is a tough thermal challenge. Generally class A refers to the fact that the BIAS is class A, and not operation at full power. Actually nearly all audio amps could be called class A amps. It is just that the class A upper limit changes making some more class A than others (e.g., some go AB at 50mW and some at 50W).

I also meant to add that the new Pass XA series is surely worth looking into (and the other Pass for that matter). Arthur
