$42,000 audio amplifier: the most efficient ever made?

For over 30 years Krell has been one of the leading names in high-end audio, so last year when company co-founder Dan D'Agostino was forced out under somewhat fuzzy circumstances, it seemed like it would only be a matter of time before he bounced back with something new.

The Momentum amplifier from Dan D'Agostino Master Audio Systems is the first result of this fresh start, and is guaranteed to get fans of the old Krell stuff buzzing. Instead of creating a monster amp the size of a car, the Momentum is positively petite at just 4-inches high. Despite this, each monoblock amp delivers 300 real world watts into 8 Ohms, doubling into 4 and again into 2 Ohms at 1,200 Watts.

D'Agostino says that the key to the Momentum's compact size is his use of pure copper heat sinks with venturi cooling, which provide much more efficient heat transfer than the traditional aluminum type. The copper is also used as a design element in the case, giving the Momentum an especially elegant appearance.

Despite the high price, D'Agostino points out that the Momentum is one of the greenest high-end amps ever built, idling at less than one watt rather than the several hundred watts the early Krells sucked up while acting as impromptu room heaters.

No further products have been shown, but it seems likely that a matching preamp will be arriving soon. I just wonder whether there are enough wealthy audiophiles left in the world to buy this type of ultra high-end gear.

The Momentum amps will be available before the end of the year for $42,000 a pair, so start saving your pennies.
