We have a rare Pioneer C21 Preamp. favorite of many a budding audiophile who either couldn't afford an Exclusive C3 or fancied the no-frills design. Reviewers of the Audio Accessory Japanese magazine very often used the C-21 as center of their test rigs well into the 1980s.
The C-21 is a stereo preamplifier composed of an equaliser amplifier and a flat amplifier and designed to display the ultimate in sound quality. It is a streamlined model and so does not feature a tone control circuit or accessory circuitry.

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).

The New NM24 DAC at Yesterday's Price
...on all DIP models. Shipped FREE to any destination in the world where mail is delivered!
Please specify AC voltage.
* New model with Headphone Amp built in!
* All Russian Sovtek 6922 tubes.
* New higher capacitance WIMA capacitors with even better bass extension.
* New bypass polystyrene capacitors.
A few words on the New Model 24
It's three units in one package: a tube DAC,
a solid state DAC, and
a tube Line Amp.(and a headphone amp)
You may evaluate the sound of the SS DAC by feeding its output(the Upper Analog out
terminals on the rear panel, see picture) back into M24's Line In, either directly with
a good (short)RCA interconnect, or better still, through a coupling transformer (more on
Then you can instantly compare the difference of the SS DAC and the Tube DAC by
pushing the button next to the volume control.
The SS version is designed to yield a slightly lower level.
It can of course be used with other Line Amps.
We have provided the additional SS DAC for these reasons:
- Many customers want tubes for the liquidity
- Others want maximum accuracy from the Solid State
- Others want deep bass(easier attainable from SS) and a subwoofer outlet
- Yet others want a coupling transformer that couples the SS DAC back
- into the Line Amp section for an instant A/B comparison
- Others want to have a SS reference when they insert different tubes

The Line Output can drive any dynamic headphones direct, through a simple RCA-to-Phone Jack adaptor. Preferred headphones are Sennheiser HD650(300 Ohms impedance)
but lower impedance headphones(Grado, etc) can also be used. We do recommend using a 300Ohm-to-30Ohm step down transformer
for Grado RS-1's.

Customer Comments on M18B:
Thank you so much. I am so impressed with my 18B- I switched from tubes and never dreamed I would be happier- and the simplicity of DAC and Volume control in one classic piece is perfect for my new ideal, and the fact that the sonics are so exceptional is of course a dream!
Monarchy Audio Model 18B Line Stage DAC
The Model 18B DAC sounds true to the music today, in the 21st century! 44.1 done right with good parts and design. Forget about bits and sampling rates.
Discover and hear what information and musicality really exists on a CD.
I compared it to my reference system CD player and the Model 18 had resolved more detail with delivering better pace and rhythm to the music. You don’t even need a line stage, it’s built in.
Or if you prefer, use your preamp, either way, the Model 18 DAC will make listening to CD’s new again.

2012 AudioExpress Review by Gary Galo: Making a decision between these amplifiers is difficult and will come down to personal taste and your specific listening requirements. If you have a true balanced source to feed your power amps and you prefer a tasteful amount of tube-like warmth in your sound, you should strongly consider the SM-70 Pro. But, if your source is unbalanced and your tastes tend to favor ultimate accuracy over what is admittedly a bit of euphonic coloration, the SE-100 MK2 will be your choice. Overall I’d rate the SE-100 MK2 as slightly more transparent, and the SM-70 Pro as slightly warmer. Either amp will provide hours of musically satisfying, nonfatiguing, high-end sound, at prices that continue Monarchy’s high-value tradition. If you’d like to help the trade deficit, Monarchy is an American company, with its power amplifiers hand-assembled in its San Francisco, CA facility. These amps are highly recommended.

What the critics are saying....
“…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
DA08 300B Tube Monoblock Power Ampifier

(this is the material other tube manufacturers use for their output transformers)
- Sophisticated output impedance selector switch (in a 4-8-16 Ohm matrix
for best speaker matching)
- All single-ended operation Mono block for infinite channel separation and devoted power supply per channel
- A combo Line Amp and Power Amp(Volume control on the front panel)
