Some comments from AT6012 customers:
"I have been living with my home built
Orion speakers for many months now. I have, during this time, tried to
drive these wonderful speakers with various amplifier combinations (DIY
and store bought), with varying degrees of success. The quality of the
sound was just not where I knew it could be after listening to
an Orion system on two occasions
with the AT6012.
I just recently took delivery of the ATI AT6012
amplifier. WOW! What a difference! There is a reason why the speaker
manufacturer recommends this amp to power the Orion speaker system; in
fact the designer of the Orion uses this amplifier himself. It simply
works extremely well. My Orion speakers have never sounded better. The
Orion’s now have more impact, more detail and clarity than ever before.
Somehow a veil has been lifted from the overall sound I was experiencing
with the other Orion/amp combos that I have tried.
For anyone interested in building or purchasing
the finished Orion speakers you should strongly consider the AT6012
amplifier to power your system. The ATI amplifier gives you a very
neutral sounding, robust and economical means by which to enjoy the
Orion speaker system."
"I have been living with the Orions for months
now and really enjoy them. I started with the ATI6012 amps and they are
indeed a great match for the Orions. In fact, Linkwitz' entire combo,
amps and cables are fabulous and tough to beat. The Orions can IMO be
taken even farther but not without a significant investment. I was very
impressed with Linkwitz recommended setup.
I did all of the internal wiring of the Orions with Shunyata cabling. I
realize that this is kind of an extreme setup but the sound is really a
revelation. I think with some minor tweaking, additional improvement can
be had. As it stands, this system provides me more musical pleasure than
any other speakers I've ever heard and I have heard many expensive
commercial speakers. All this said, Linkwitz recommended setup is
marvelous and well worth following, if economically possible." |

The AT6012 is the perfect solution for your Orion
Loudspeakers. It is the amplifier that has been spec'd into the design and
recommend by Linkwitz Lab for the Orion speakers.
This 12-channel power amplifier
incorporates the same legendary sound and design criteria as our other award
winning amplifiers–without exception. The AT6012 consists of six 2-channel
modules and each module’s volume (gain) can be remotely adjusted. While
elegant in concept and design, the AT6012 is rugged and will withstand the
rigors of even the most demanding requirements. Critical components such as
toroid transformers and circuit boards are manufactured and assembled in our
own factory, guaranteeing consistent quality control. Features including DMC
(Detachable Modular Component), Remote-Power-On and our Isolated Optical
Protection Circuit are but a few of the advanced design concepts that add up
to make ATI amplifiers the best value in the industry. Circuitry in the
AT6012 is totally complementary from input to output using dual-differential
input stages. Pre-drivers then drive the full-complementary output stage.

Made In The U.S.A.
The U.S. has always led the world in power amplifier technology, and still
does. All ATI products are manufactured in Southern California in a modern
50,000 square-foot facility to exacting design specifications and rigid
quality control. ATI manufactures all toroid transformers and assembles
all circuit boards in-house. We use computerized Audio Precision test
equipment to test each stand-alone amplifier module (DMC2) as well as the
completed unit. This control and scrutiny of every phase of manufacturing
guarantees unit-to-unit repeatability and a lifetime of accurate sound
reproduction.
