The ProLogue Two is a KT-88
based vacuum-tube integrated amplifier, hand-made with the finest point to
point wiring, using workmanship that is equal to or better than any product
you can buy at any price.
The amplifier is built using finest premium parts. A toroidal transformer for the powersupply.
Custom designed -in conjunction with one of the most prestigious
transformer-designers in the USA- encapsulated output transformers for lowest
hum, wide bandwidth for great bass and extended highs. Ceramic tube sockets.
ALPS volume control. Nichicon and Solen capacitors.
Gold plated heavy duty speaker terminals and gold plated input jacks.It is enclosed inside a heavy gauge steel, fully
vented chassis with five coats of finish. Each coat hand rubbed and polished.
The Adaptive AutoBias™
circuit, an exclusive to PrimaLuna, monitors and smoothfully adjusts bias constantly and instantly,
reducing maintenance and increasing performance because of a dramatic
reduction in distortion. For extended life of tubes and switches plus a
reduced chance of tube failure/shorts, the amplifier uses a soft-start
circuit.
Tube plate fusing is used to protect the output stage.
Other amps might need a trip to the shop if a tube fails. Not this one. Just
plug in a new tube and fuse, and go.
All PrimaLuna models come
standard with a quick-release tube cage. The cage is held in place using
banana plugs, so taking the cage on or off is a breeze. The finish of the
amplifier is a fine charcoal color with a slight hint of metallic. The high
gloss finish screams quality. The rear transformer cover is vented to allow
heat dissipation.
