Threshold S/5000e new amp too good to be true???

I've just read the Soundstage review of this amp and it's too good to be true for it's $2500 brand new price. It was compared to solid-state amplifiers in the $5000 price range, including Aragon Palladium monoblocks, a Simaudio Moon W-5, a Plinius SA-100 Mk 3, Gamut D200 Mk 1 and Mk 2 amps, and an Ayre V-5x. If this amp is up to this big amps costing 2 to 3 times, how come I don't hear or read people raving about it?
Here is the link to the Soundstage review. http://www.soundstage.com/revequip/threshold_s5000e.htm

Good points Loudandclear. Still ... the weight difference makes you wonder. Certainly class A runs hotter, but 250 wpc in class A would require a pretty hefty power supply, wouldn't it? At minimum, as you stated, it should require even more in heat sinks. Like Rockvirgo, I'm still scratching my head about the weight.

Ozfly,

I checked with Threshold and the S5000/e has 45 watts per channel of Class-A before it switches to Class-B.

45wpc of class-A is very high bias for most class A/B amps.
That's why it runs so HOT.
You gotta wonder if there is enough heat sinking there.

I recently installed a Threshold S/5000e in my system, and I can only comment that the Soundstage review was quite accurate. It's a superb amp, especially for the money (currently $3000). The previous forum comments about it running too hot are incorrect in my estimation. It just runs "very warm" - i. e. you can hold your hand on it indefinitely without getting uncomfortable.
