D'Agostino Momentum amp melts down

I'm an old fud and the last thing I want is attention but after reading the sonic description in that review I wouldn't mind comparing them to my Constellations (which are currently powering the Magico Q7's residing one of my dream systems).

Lets face it QSC makes amplifiers that can run all day at that load if you don't mind the sound of a high capacity switch mode power supply. Not to discount the test but according to the review the power meter barely got off the peg in listening tests. If the manufacture stands behind the design who cares.

I trust any ultra high end audio manufacture to funnel profits back into the system more than some 1%'er, screw them. Besides, they're an important function of the used market. We need to stop wising up these chumps.

I am sorry that you interpret this as a melt down. The Momentum amplifiers normal operating temperature is 42-44c(107-111f)the temperature rise to 48c (118f) is inconsequential. The amplifier in question failed from a non related component failure in the power on circuit.The Momentum amplifier is designed to shut down at 70c (158f). The unit under test was not close to that temperature.Many amplifiers at higher temperatures than that.If John had continued his test the second amplifier would have passed witout any problems. The Momentum amplifier has more than enough thermal head room for any load or speaker. I was unable to give comment until the unit was returned to me from testing. Thank you for your concern.

I have a pair of Krell LAT 1000's and would love to hear any comments on whether they'd sound better driven by a set of Krell Evolution One's or Dan's new Momentum 300 monos.  Consider the listening environment a neutral factor in your analysis, if you can, ha.  For the boisterous critics here, I'm a fan of pretty much all of Dan's work.

Best,
Justin
