Classe Omega Power Amplifier

Beschrijving / Description

The Omega is a handsome, manly beast. Its backbreaking, 250-lb. weight is nicely offset by its black-edged, "soft-shadow," brushed-aluminum cladding, supported by huge square black towers at the four corners. The chassis itself is made of nonmagnetic steel, and the thick-as-the-dickens heatsinking, also in chic black, is built up of bolted-together modules, with vertical fins that are double-width at section joins. But, beefy though it is, the heatsinking isn't very elaborate, and doesn't have to be. The Omega runs class-A up to 110Wpc, then tips into class-AB at power levels above that. It got nice'n'toasty after an hour or two of high-decibel onslaught, but never turned into an oven.

The interior is also a treat for the audiophile eye. It's all polished high-tech in there, the huge double-toroid transformers up front adding the aura of an exotic engine.

The Omega is actually two completely separate amplifiers within a single chassis. The two huge transformers (2500VA each) sport their own power cords (Cardas Goldens, supplied) and feed a main storage capacity 90,000uF per side?made up of a number of small capacitors. There are 16 bipolar (high-voltage, high-current) output transistors per side, for a grand total of 32. Audiophile goodies abound: metalized polypropylene capacitors bypass each output device, and you'll find four large Solar metalized polypropylenes on the DC supplies of each dual-mono section. Two heavily gold-plated bars connect the output transistors' voltage supplies, all wiring is of oxygen-free copper, and all signal-carrying cables are Litz-shielded "to minimize skin effect."

'Round back, the Omega's luxurious demeanor continues with heavily gold-plated balanced (XLR, pin 2 hot) and single-ended (RCA) input connectors above, and four large, gold-plated output terminals below. The custom posts are battened down with a supplied nut-driver of top quality. They don't fool around in Canada when it comes to their tools, Two sets of generously spaced outputs make for easy biwiring, although our JMlab Utopias take a single-wire input. The outputs are well marked for bridged operation should the urge for greater power overcome you. But careful one of the positive output terminals becomes negative in bridged operation.
