Great condition and sound. An amplifier that will put a smile on your face!
Bill Schuchard StereoMojo "The Jaton AP2140A has a tight yet hefty
bottom end, a transparent articulate midrange, delicate highs, razor
sharp imaging, and is dead silent when there is nothing to play. It was
never bright or edgy and the bass emphasis came through nicely." "The
Jaton Operetta AP2140A is a great sounding amplifier and exceedingly
Doug Blackburn HomeTheaterSound: "I’ve heard $1995
two-channel amps with less clarity and musical nature. The Operetta’s
midrange made it difficult to stop listening."
Finding out that the
Operetta amplifier could drive my loudspeakers to loud levels wasn't the
only surprise. This amp also sounded great - it is quite pleasing and
detailed. Vishay resistors, and Nichicon and Wima capacitors used
throughout. This is truly an amp that put a smile on your face. It will
please 99% of audiophiles. In both build and sound quality, this is
easily a $3K amp, listing for half of that.
Elegance, simplicity and
attention to detail rule its design. At its core sit two power modules
comprising National Semiconductors' LM3886 High-Performance Audio Power
Amplifier IC. Each module produces 70 watts into 8 ohms, modest by
modern standards, but like tube amps, these are sophisticated watts.
More importantly, the combined attention to circuit geometry and quality
components yields power with total harmonic distortion so low it left
National Semiconductors' own engineers double checking their
All of this represents an elegantly radical approach to
circuitry so effective as to belie numbers. The proof is in the
listening: laser-like focus, precise separation, deft detail, and
