D'Agostino Momentum amp melts down


The latest issue of Stereophile tests the Momentum amplifier and amp number 1 melts down during the precondition test. Atkinson is afraid to subject amp number 2 to the same test and only runs it for 1/2 as long as the standard test.

Parasound, Bryston, and others pass this test but the Momentum can't? Then they act like it's no big deal like it melted down. So, if that's the case, why perform the test?

The manufacturer response doesn't remark on the melt down. I would think Dan would be duly embarrassed but what the heck, those copper heat sinks sure look great.

Would a prospective buyer (not me) be hesitant to power an inefficient speaker to loud levels with this amp?

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.
