emotiva mono block amps any good?

Tony, that's good research. Reviews of the XPA have been very mixed, but the XPR looks like a step forward. Funny...I was wondering about the Class A wattage myself.

Anybody know if the reference series amps are a step up from the XPA? ie; XPR-1 vs. XPA-1 and I'm not just talking about the obvious increase in output power.

"I have heard amps in the XPA line and based on the experience and for the same money, I'd take the Belles all day long."

Totally; XPA is not in the same league as amps mentioned above. But any info on the XPR Reference line? Is it a redesigned amp?

thanks Tony for ur insight. As far as doubling power from 8/4 ohms, there are other high power amps that come close to that spec and provide high current, so I agree with you.
Yeah, not much info on these amps, but what I find so funny about the Emotiva website is read how many times they use the term "audiophile" in their descriptions of their products.

I was expecting about 10 watts class A from an amp that massive.
From when I was researching Bob Carver designs; an explanation...

Class G amplifiers (which use "rail switching" to decrease power consumption and increase efficiency) are more efficient than class AB amplifiers. These amplifiers provide several power rails at different voltages and switch between them as the signal output approaches each level. Thus, the amplifier increases efficiency by reducing the wasted power at the output transistors.

Class H amplifiers take the idea of class G one step further creating an infinitely variable supply rail. This is done by modulating the supply rails so that the rails are only a few volts larger than the output signal at any given time. The output stage operates at its maximum efficiency all the time. Switched-mode power supplies can be used to create the tracking rails. Significant efficiency gains can be achieved but with the drawback of more complicated supply design and reduced THD performance.
