"The Worlds Largest Seller of Ultra High End Audio"   



Super hard to find Reference grade multi-channel Audio Research MP-1 preamp with remote. Legendary sound, ultimate flexibility for using in both a 2 and/or a multi-channel system. For the truly demanding audiophile who demands the highest quality possible. Comes with original factory box and remote control.

Here is an opportunity to own the ultimate Analog Multi channel Pre-amplifier ever made.

The Audio Research MP-1 is the highest resolution multi-channel preamplifier in the market. It is designed for the Multi-channel purist Audiophile. Just hook it up to a high resolution multi-channel digital source with analog multi channel outputs like the Oppo and you will treated to spectacular sonic delights from SACD, Blu Ray, DVD-Audio and DVDs - better than any Processor!

It has enough balanced and unbalanced inputs for accommodating a variety of high resolution analog sources!

The MP1 will be appreciated by the most discriminating music lovers, offering control flexibility and an extraordinarily high level of performance which is simply not available from other multichannel analog or digital products.

Although many fine home theater processors can input a six channel analog signal, I have not heard one which performs this task to the highest musical standards. This should not be surprising since these products, by their nature, include a lot of circuitry -unnecessary in this case - for digital video and audio processing. This circuitry typically contaminates the high-resolution analog signals of SACD and DVD-A. Even if the digital and video circuitry is defeated or bypassed, the analog stages of these processors still do not provide the desired musicality and resolution. 

The MP1 is an elegant and wonderfully musical solution for the playback of these multichannel analog formats.

As one would expect from a preamplifier of this caliber, many circuit details have been derived from the Reference level stereo line stages. 

The pure Class-A circuitry is fully balanced in a double differential design, utilizing all-FET circuits with unity-gain buffers between stages and a double-buffered output. Low-noise, high trans-conductance JFETS are used for all audio circuits, with local FET constant-current stabilization for each stage. The audio circuit is DC coupled throughout, with servo stabilization for low offset and subsonic control. The massive power supplies have ten wideband and high headroom audio regulators utilizing constant-current source stabilization. 

Total gain is an extremely dynamic 15dB balanced, 9dB single-ended output.

Sonically, the six-channel MP1 blends powerful dynamics, high resolution, great frequency extension, and see-through transparency with a relaxed musicality that is much sought after but rarely found. The MP1 will easily complement the most refined two channel music systems and the most outrageous theater systems.

The MP1 is an important new product that helps integrate the worlds of two-channel and multichannel music and multichannel home theater in one elegant, easy-to-operate package. 

You will be smitten by its rugged build quality, insightful and involving musical performance and intuitive operation.

The MP1 was designed for maximum flexibility, with three sets of six channel inputs; two sets are SE, the third offers the choice of XLR or SE connection. 

Any (or all) of these inputs can be used as a six channel unity-gain-through for use with a home theater processor. 

There are also four sets of SE and XLR stereo inputs, a stereo Record output and one set of six channel SE and XLR main outputs. There is, of course, a 12V remote trigger, although the MP1 can be left on continuously for best sonics.

With its chassis the same size as a Reference preamplifier, the MP1 is physically impressive. Each of its six channels is on a vertical, modular plug-in board with gold plated gas-tight connectors. The mainframe chassis contains massive, fully regulated power supplies utilizing two ultra-quiet transformers. 

The front panel contains a large vacuum-florescent display on the left, indicating volume control display (in 0.5dB steps) has large, easy to read 3/4 inch numerals with six brightness levels, plus off. When the display is turned off, it can be reactivated (at its lowest brightness level) for ten seconds by touching any button on the remote.

On the right side of the front panel is a cutout which contains two rows of six buttons. The top row includes Power, Mute, Processor, Multi 1, Multi 2 and Multi 3. On the bottom is

CD, Stereo 1, Stereo 2, Stereo 3, Vol down and Vol up. (This is the first Audio Research preamp with direct access inputs). 

The remote accesses several additional functions including Level adjustment for all six channels, BAL/SE selection for those inputs with both XLRs and RCAs, Invert (phase). Display brightness, and Stereo/Multi, which outputs two channel stereo from a multi-channel input.

We have a massive list of positive feedback over many years from Audiogon buyers many who purchased items over $25,000 and paid in advance via wire payment.
As the owner of HigherFi, a couple of years ago I contracted double cancer and was forced to stop selling audio gear while I fought for my life. Having made a complete recover, I am now back on Audiogon but they tell me they cannot recover my long list of past clients. I have 100% feedback on eBAY since 1998 still today and as you can see above I am the only online dealer here with references from the EDITORS of most of the top audio publications so you know you are in honest and ethical hands when you purchase from us.  

Having been an audiophile and a reviewer for over ten years, I have dealt with many people in the industry. My experience with Chris Moon of was one of the smoothest, hassle free experiences I have had. I'm sure we will work together again soon. Thanks,  Greg Petan, Managing Editor/

"HigherFi is an honest, forthright seller of used high-end audio equipment. I have known Chris for over ten years and he has always been above board, knowledgeable, and a very good communicator. I would surely recommend him to anyone looking to sell very high-end audio components on a world-wide stage. I'm not sure there is anyone in the business today that's sold more gear in the uber-end of the market. What else can I say? Highly recommended!"  Jeff Fritz , Reviewer with UltraAudio 
Dealing with Chris at HigherFi reminds me of the good old days. He's good people and I respect his advice and square dealing."  Wes Phillips - The Absolute Sound 
"I had the pleasure of setting up a Genesis 1.1 Loudspeaker system with my buddy that was purchased through HigherFi. The buyer was very happy and we had a blast dialing that system in! Chris seems to have all the great toys and the knowledge to get them pumping out fantastic music."  Michael Mercer, HPSoundings and Positive Feedback
