Spectral DMA 360 pair. Upgraded to current Spectral knurled metal feet on both amps. A few scratches here and there but nice fronts.Paypal users please add fee.

These were sold however the buyer seems to have disappeared, even after sending me a deposit. Very strange...but, now you have the opportunity to own one of the finest set's of amps around.

From RH, 2009:

"As I got to know the Spectral electronics during this short time
with the V3 and later, in more depth during extended listening
with the Wilson X-2 (a setup I’ve listened to nearly every day for
the past six months), several salient sonic characteristics emerged.
First, no other electronics I’ve heard reproduced a soundstage
like this Spectral system. The sense of three-dimensional space
and of tangible instruments populating that space was staggering.
It wasn’t just that the soundstage was wide and deep; I had the
distinct and unique impression that the air was “charged” and
alive. Even before the first note of music, as the hall sound fades
up, this quality was unmistakable. I attribute this perception to
the system’s extraordinary ability to reach down and present the
finest spatial cues, fostering a more convincing impression of
being in the presence of the live event, surrounded by the hall’s
acoustic signature.
The Spectral’s recreation of an orchestra’s sheer size and scale
was unmatched, in my experience. In addition, the soundstage hada crystalline-like clarity that made quiet instruments
at the back of the stage vividly palpable rather than
murky or indistinct. The placement of instruments
within the surrounding acoustic was razor-sharp,
with a tangible sense of air between them. The
layering of instruments was super-resolved, with
no blurring of images or ambiguity of placement.
This quality was most apparent on naturally miked
classical recordings, but also served other types of
music. I heard a clarity of arrangement, of separate
musical lines contributing to the whole, that no other
electronics have equaled. Instruments were presented
as separate objects spatially as well timbrally, in the
way that we hear in live music. The presentation
was the antithesis of flat or congealed. This made it
much easier to hear how the individual instruments
contributed to the larger composition—and thus the
composer’s intent. Hearing the music resolved in
this way was immensely involving and rewarding.
The second quality in which the Spectral
electronics was unsurpassed was their sense of
speed and dynamic agility. Transients seemed to
jump out of the soundstage as if from nowhere,
and then to disappear just as quickly. This was
true not just of very high-level transients, but also
of smaller-scale dynamics. Hand-held percussion
instruments, for example, had the almost spooky
vividness and immediacy that one hears in life. And
on big orchestral climaxes, the Spectral system was
completely effortless and composed, with no sense
of strain, dynamic compression, or congealing of
the soundstage. The system’s dynamics served all types music; rock drummers locked into the groove,
snare pops grabbing my body in a visceral way.
Despite the system’s extraordinary dynamics,
the presentation had absolutely no sense of etch,
of hyped transients, or other artifacts that quickly
become fatiguing. This combination of ease
with seemingly unlimited dynamic contrasts was
extraordinarily satisfying musically."
