Audio Research Reference Two
High Definition Preamplifier
Available for sale is this 1st Gen Ref Two MK II Preamp
. I rated it an 8 for age, but there are no
known flaws visually, mechanically and sonically.
Inherited from original owner. A total Stereo / Audiophile that had the money
and good sense
to purchase new and have every repair and many upgrades
performed direct by Audio Research factory. Unit probably has minimum hours on
it before being re-boxed and stored away. Comes in original boxing.
Accepting CC, bank wire, money order. If
you meet my asking price I will include FEDEX shipping and insurance.
"How advanced is the REF2MKII in sonic performance? It is as much an
improvement as the LS25MKII was over its predecessor -- which is to say it is
immediately audible and musically profound. Image focus, clarity and a sense of
body are all heightened -- where by contrast the original version is simply
less vivid overall. Dynamically, too, the MKII picks up the pace in a startling
manner, making the rhythmic line and structure of any musical selection much
more evident and understandable. The ebb and flow of a bass line, percussive
textures, and time changes now make more musical sense as you hear them revealed
by the greater immediacy and dynamic freedom of the REF2MKII. Finally, the MKII
presents the music with a solidity and focus and coherence that is simply not
present to the same degree in the original. From top to bottom, then, the
REF2MKII is another advance of the state of the art in line-level
