Luxman A3550

In the 80's Monarchy Audio was the USA kit distributor for Luxman Japan. This model (Luxman A3550) was offered as a kit at a lower price than finished Luxman products. Luxman built a few finished kits for demo/display. The A3550 offered here is such a "factory assembled kit." Monarchy Audio subsequently upgraded these "demo/display amps" with German WIMA and other film caps, bias regulation, and Teflon silver wiring for enhanced performance. A pair of 4-Ohm outputs were also retrofitted to match other  4-ohms speakers (original 8-ohm outputs retained).

What the critics are saying....

SM70 Pro“…Sweetly detailed and warmish when used as a single-ended stereo or mono amp, but running fully balanced, the SM-70 Pros exhibit a level of transparency that is simply awe-inspiring. Their clarity and punch are amazing.”
Wes Phillips – SoundStage

“…Maintaining harmonic integrity is essential to preserving the tonal qualities of the instruments and allows them to be reproduced in a manner that more closely resembles their respective natural sonic signatures. In this one area the SM-70 Pro can compete with the very best amplifiers available, tube or solid-state.”
Frank Alles - The Stereo Times

“…Sonically the SM-70 Pro amplifiers offer extremely high value.”
Gary Galo -AudioXpress

“…sets the benchmark for performance in the sub one thousand dollar category.”
John Hoffman - Affordable Audio

“…They have an effortless and authoritative presentation, as well as loads of transparency. ”
M.L. Gneier - The Sound Mind

“…as monoblocks, these amplifiers possesses a lot of authority and add much more impact to the sound.”
“…The SM70 Pro was neutral enough that it revealed the character of whatever preamp I hooked up to it.”

Jeff Dorgay - Tone Audio

“…and showed just how much musical fun you can have for very little cash.”
Dave Clark- Positive Feedback

“…As far as single ended, medium-power, fully-balanced, solid state monoblocks are concerned, the Monarchy SM-70 Pros are in a class of their own. Recommended.”
Victor Chavira - Positive Feedback

“…This is a lot of amp for the money!”
Martin DeWulf – Bound For Sound

“…A single SM-70 makes some lovely sounds. It has an expansive presentation and really lets the music breathe.”
Paul Cervantes- Ultralinear

Custom Made in AmericaMonarchy System

The SM70 Pro (Compare the SM-70 and SM-70 PRO), and the SE-100 MK2 are hand-assembled in San Francisco, CA, like all Monarchy power amps. Years after first being introduced to the public, and while continually being improved upon, they are still getting high-praise/reviews. Read the October 2012, AudioExpress review by Gary Galo: Monarchy SE-100 MK2 & SM-70 Pro Power Amplifiers. These two amps are the only low cost amps on the market that can be operated in True Balanced Mode when operated as a Mono Block using the XLR Input terminal.
