Founding Philosophy & Business Principles
An overview of C.C. Poon’s ethical framework and business philosophy as the founder of Monarchy Audio.
Comments by Gemini
Business Ethics Essay“The business ethics of C.C. Poon are widely regarded in the high-end audio community as a masterclass in consumer-first, value-driven engineering… His ethical framework can be broken down into four defining pillars: ‘True High-End at Low Cost’, The ‘QES’ Design Philosophy (Quality, Economy, and Simplicity), Separation of Profit from Passion, and Direct Accountability & Customer Accessibility… C.C. Poon’s legacy is that of an educator-turned-engineer who viewed the high-end audio business not as an extraction mechanism for wealthy hobbyists, but as an egalitarian service to music lovers.”

商業道德觀（中文版）“C.C.的商業道德觀在高階音響社群中被譽為以消費者為先、以價值驅動工程的典範。其核心哲學可歸納為四大支柱：‘真正的高階，平民的價格’、‘QES’設計哲學（品質、經濟、簡潔）、利潤與熱情的分離，以及直接責任與客戶可及性。… C.C.的遺產是一位從教育工作者轉型為工程師的人物，他將高階音響事業視為不是為富裕愛好者剝削的機制，而是服務音樂愛好者的平等主義事業。”

Digital-to-Analog Converter
The Golden Ear award-winning NM24 — and its M24 predecessor — set the standard for affordable high-end digital conversion. Critics hailed them as "regal, natural sound" and "music's magic on a budget" — genuine high-end performance at an affordable price.
Comments by Gemini
Business Ethics Essay"The Monarchy NM24 teaches us three important lessons about digital-to-analog converter design… Its sound character is exceedingly analog-like, as the NM24 sidesteps the halo of brightness that permeates the harmonic textures of so many delta-sigma-based DACs. You'll have to look in the neighborhood of $5k in order to exceed its performance."
Dick Olsher, The Absolute Sound, November 2015 View Full Review (PDF)
★★★★★Stereo Times"In my view the Monarchy M24 DAC/Line-stage is a remarkable product. The DAC or the tube line stage by itself would be worth Monarchy's low $1490 price, but to get both units rolled into one very attractive component definitely strikes me as quite the sound bargain."
Clement Perry, Stereo Times, July 2006 View Full Review (PDF)
★★★★★Dagogo — M24 & SM-70 Pro"It gives tremendous value for the money as the M24 is a three device unit — SS DAC, Tube DAC and Tube Line Amp, all in one package… do not let that dissuade you if you are in search of economical excellent performance."
Doug Schroeder, Dagogo, August 2008 View Full Review (PDF)
★★★★★Dagogo — M24 & SM-70PRO"The SM-70 Pro and M24 tube DAC Line Amp have a very special magic combination of energy and ambience. At all volume levels this system delivers a fantastic mix of detail and full-range sound… In conclusion, I could completely live with this system for a very long time and always have a smile on my face."
Sandy Greene, Dagogo, March 2006 View Full Review (PDF)
★★★★½HighFidelityReview (from Affordable Audio)"To the best of my knowledge, this component is unique in the audio world due to its multiple configuration design… Combine the NM24 with a high quality amplifier such as the SM 70 PRO, and you can create a system that will run circles around some very expensive gear. If you get a chance to audition a NM24, you really should do so, and don't be surprised if it stays in your system."

★★★★★Paul Cervantes"It is very hard to imagine any other amplifier at or near its price that can match its musicality… The Monarchy SM-70 Pro is a fine stereo amp that is both gutsy and refined."
Paul Cervantes, ultralinear.net, 2006 View Full Review (PDF)
★★★★★SoundStage! / StereoTimes"If your speakers are of moderate to high efficiency, the truth is that the Monarchy Audio SM-70 Pro is one of the best sounding amplifiers you are likely to encounter in your search for the elusive 'Holy Grail' of audio amplifiers… Simply stated, it helps to keep the 'muse' in the music."

MOSFET Power Amplifier
The 100W SE-100 MK2 MOSFET power amplifier has been praised for its authoritative power delivery and refined sonic character.
★★★★★Bound for Sound"In my eyes, the Monarchy SE-100 delux mono power amplifiers are notable, not for some ground breaking new discovery, but for their superb use and application of well understood but still notable amplifier technologies… These Monarchy amps represent, instead, the applied application of tried and tested ideas in an immensely practical way. How else can one get this kind of sound for so little money?"
Martin G. DeWulf, Bound for Sound #209 View Full Review (PDF)
★★★★★Audio Express"Together with the SM-70, the SE-100 MK2 represents the vanguard of affordable high-end amplification. The 100V rail design delivers headroom and authority that belie its modest price."

★★★★★Enjoy the Music"For me I liked the MK2's and would rather spend the money I saved with buying them, on better loudspeakers and source components… High End at Low Cost which is a very appropriate description of the new MK2's."
Anthony Nicosia, Enjoy the Music.com, November 2009 View Full Review (PDF)
★★★★★SoundStage!"In my opinion, Monarchy has succeeded in making a very good amplifier demonstrably better… For the asking price, I can think of NO other amplifier that I'd prefer to listen to."
Frank Alles, SoundStage!, February 1999 View Full Review (PDF)
★★★★★SoundStage!"The Monarchy SE-100 Delux monoblocks are superb amplifiers. They are well built and offer high-end sound that is sweetly detailed and authoritative… They may be small, but they're choice."
Wes Phillips, SoundStage!, April 2002 View Full Review (PDF)
MOSFET Power Amplifier — 160W/Ch
The SE-160 delivers 160 watts per channel of MOSFET muscle, bridging the gap between the refined SE-100 and the formidable SE-250 with warm, tube-like tonality.
★★★★★SoundStage!"C.C. Poon consistently produces amplifiers that boast tank-like power with single-ended-worthy finesse and excellent articulation — all in compact packages whose prices make most audiophiles do a double take. The Monarchy amps' imaging and soundstaging are champs."
Ken Micallef, SoundStage!, December 2003 View Full Review (PDF)
★★★★★Stereo Times"High-Power Hybrid Monos Make Music! The SE-160s are very dimensional sounding amplifiers and throw a very wide soundstage with a good sense of depth and excellent placement of individual instruments and voices. The fact that the audiophile can tailor the amp's sound (by tube swapping) to match his taste and system characteristics is another very real benefit. The Monarchy SE-160 amplifiers are among a rare breed of products that can fool the listener into imagining he is witnessing a live musical event."
Frank Alles, Stereo Times, April 2001 View Full Review (PDF)
★★★★Secrets of Home Theater & High Fidelity"These guys have a much warmer sound than the SE-100 Deluxes. They may cost more, but I find them far more musical. Hilary Hahn's violin and orchestra sounded far more liquid than with the SE-100 Delux. C.C. Poon definitely has a good thing going with his products. In the right systems, his power amplifiers will deliver much pleasure."
Jason Victor Serinus, March 2004 View Full Review (PDF)
Hybrid Monoblock Power Amplifier — 250W/Ch
The SE-250 pairs a dual-triode tube input stage with MOSFET output for 250 watts of class-leading power, delivering SET-like bloom with effortless drive.
★★★★★Dagogo"The Monarchy SE-250 hybrid monoblock amplifiers are great amps when you need power. I find them quite attractive and well made. I think they are quite a bargain… they aren't that far behind world class, which amazes me at such a reasonable price for so much power."
Jack Roberts, Dagogo, December 2007 View Full Review (PDF)
★★★★½Secrets of Home Theater & High Fidelity"Let's cut to the chase. I really like the sound of these amplifiers… The SE-250's single-ended, zero-feedback design lets the music blossom."

★★★★½Secrets of Home Theater & High Fidelity"The upgraded SE-250 is even more convincing… C.C. Poon's changes to the circuitry have made an already fine amplifier more musical."
Jason Victor Serinus, June 2006 View Full Review (PDF)
★★★★HighFidelityReview"The Monarchy SE-250 monos offered a beautiful, natural midrange and superb bottom-end drive… a compelling alternative to the class-D H2O Signature 100."

Power Conditioner
The AC-Regenerator has been honored with multiple awards and praised for its transformative effect on audio system performance.
★★★★★Stereo Times"The simple truth is that using the Monarchy Audio AC-Regenerator has opened my eyes to the need for supplying pure AC power to my source gear… After evaluating the Monarchy unit and hearing the extent of the improvements it affords, I'm convinced that its use is not an option—it's a necessity. The Monarchy AC Regenerator is now an integral part of my audio system; thank you very much!"
Frank Alles, Stereo Times, August 2006 View Full Review (PDF)
★★★★½HighFidelityReview"My listening experiences show that the Monarchy AC Regenerator is capable of elevating the performance of every component that I have tried it with… If you are looking to take your system to the next level of sonic performance, then consider the quality of AC you are providing your stereo with. You may be pleasantly surprised at what improvements can be coaxed out of your current equipment."

Jitter Reduction & Signal Conditioning
The Monarchy DIP (Digital Interface Processor) cleans the digital datastream between transport and DAC — reducing jitter, re-clocking the signal, and (in upsampler versions) adding dither and upsampling. Critics across three continents have called it one of the most economical additions a digital system can make.
★★★★★What Hi-Fi?"This product performs outstandingly between CD players and DACs, tightening focus, adding pace and attack… Without it the music sounds noticeably slower, less exciting and murkier. The DIP just gives you more of the music… Simple, yet simply addictive, the DIP's a bargain."
What Hi-Fi? (UK), reprinted with permission View Full Review (PDF)
★★★★★Stereophile"I highly recommend the Monarchy Audio DIP 24/96 for owners of the Link DAC III with upsampling—for $249, it's almost a no-brainer… The DIP substantially improved the sound of my Link DAC III, especially when upsampling was engaged. The sound became cleaner, clearer, smoother. Transient definition improved… If upsampling is the cat's meow, the DIP is the cat's whiskers."
Sam Tellig, Stereophile, February 2001 View Full Review (PDF)
★★★★★SoundStage! / Planet Hi-Fi"Six months ago I reviewed the Monarchy Audio DIP 24/96, and I remain stunned by the little unit's performance, especially considering its $249 price tag. In my mind, no digital front-end should be without one… the DIP 48/96 Upsampler, dollar for dollar, one of the most economical investments for your system. The music was fuller, more robust, especially in the lower region where string bass had more authority and weight."
Greg Kong, SoundStage! / Planet Hi-Fi, April 2002 View Full Review (PDF)
★★★★★Positive Feedback"This box is flat out the very best digital signal conditioner I have encountered, at any price… It is at the top of the heap! No other digital signal processor I tried even comes close… Amazing it is, and at the super affordable price you simply must have one or two. Very highly recommended for any digital audio system, regardless of expense. Six Stars indeed!"
Jennifer E. Crock, Senior Editor, Positive Feedback View Full Review (PDF)
★★★★★Affordable Audio"In summation I must say that considering price versus performance both products from Monarchy Audio are a sound investment. As for the new DIP/Upsampler Combo I was extremely impressed… the Combo's price is $149 less… Using only one slightly larger enclosure, instead of two, you need now buy one less digital cable and one less after market power cord."

2000W AC Isolation Power Supply
The Monarchy M150 is a 2000W AC power isolation conditioner that transforms the power delivery to your entire system. With dual isolation transformers, EMI/RFI filtering, and 12 outlets, it eliminates noise and improves dynamics, bass, and clarity across all components.
★★★★★Bound for Sound"This pizza box, together with the Homegrown wire, made the most significant improvement to my reference listening gear in the past five years."
H. Richard Weiner, Bound for Sound View Full Review (PDF)
★★★★★Affordable Audio"The problem with the M150 is that once you give this beauty a try you will be hard pressed to take it out of your system… Monarchy Audio products have a way of spoiling you and the M150 is no exception. They always sound like high-end gear should yet they are priced for the value minded audiophile."
