Krell KAV-150a Power amplifier, new condition, very rare!

This is new old stock, it was in
climate control storage for several years. 
Very rare in this condition and a real find for Krell enthusiasts. 

I tested it in my system and it sounded fantastic.

I don’t have original box but the amplifier will be expertly
packed, check my feedback about packaging.

Shipping is $35 in the US.

 The KAV-150a uses proven Krell®circuits built with the same
high quality resistors, output devices, and internal electrical components used
in all other Krell®products. From input to output, the KAV-150a uses discrete,
fully complementary circuitry. All circuits up to the driver stage operate in
pure Class A. The KAV-150a employs a wide bandwidth design with a very low
negative feedback for sonic accuracy throughout the frequency spectrum.

Micro & macro dynamics

When the musical program requires impact, the KAV 150a shows
you all the dynamic power it possesses, transferring large amounts of sheer
energy to your drivers and to your body.

It does not sound violent: the energy is offered quite gently, which is quite
unexpected for a hi-power solid state amp.

It sounds dynamic but not exactly explosive, it is powerful but not aggressive.
It is possible to listen to it for hours and hours, at high levels, withot ear
"fatigue", a clear sign of class. In fact, you know when you're
testing a good amp when after 4 or 5 hours of listening at high levels you can
still turn the volume up without willing to turn everything off instead.

The driving capabilities of the KAV 150a are good, it can virtually
"shake" any driver, even the laziest one. Even in large rooms, with
mid-efficiency loudspeakers, the amount of power is more than sufficient for
adequate home listening sessions.

The KAV 150a is very good at microdynamics, too. Not exactly
"analitycal" or "razor sharp", it still unveils good
amounts of tiny details and variations, though its ability to sound with grace
makes it sound smoother than it actually is. 

The sense of speed and pace is average: it follows the Music with ease and
attacks and decays are natural, withot being too "sharp" and violent.

Soundstage

Good. Wide and deep, well focused with smooth contours. The
height of the image is surprisingly good and so is depth, sometimes even
excessive: with the Reference Recordings Berlioz's Sinfonia Fantastica some
portions of the orchestra appear to be even too far (or more than needed :-) )

There's much air among the instruments and the illusion of a 3D event is very
realistic. Not the soundstage of the top-of-the-line Krell amps but still a
good performance, given the price. The sound is NEVER "in the face"
as is usually expected with hi-power solid state power amps.

Conclusions

Grace and power live together in harmony here. The KAV 150a
is the first step into the golden world of Krell amps and it should be
seriously considered by anyone who's searching for a powerful amp with a gentle
sound.
