When Monarchy was founded in 1979 by C.C.Poon, the company sold amplifier kits from Japan. The major brand carried was Luxman. In the 1980s, Monarchy focused on shipping Threshold products designed by Nelson Pass to the Far East. The company also established a network selling computer chips.

In 1990 Monarchy introduced the Model 20 D/A converter. Hot on its heels came the Model 22, a dual 20-bit DAC using the Burr Brown PCM63P-K chips. This was hailed by a reviewer from Audio Observatory as sounding better than the Mark Levinson DAC at 10 percent of the price. Audiophiles on a budget, who appreciate Monarchy's philosophy of selling "High End at Low Cost", have enthusiastically supported the Model 22 series.

One of Monarchy's most cost effective products is the DIP (Digital Interface Processor), which won acclaim all over the world. The original version debuted in 1995. The latest incarnation, the DIP 24/96 , won "Best Buy of the Year" from the audiophile press two years in a row. Sam Tellig, Stereophile's Audio Cheapskate, says of this product in the February 2001 issue, "The sound became cleaner, clearer, smoother. Transient definition improved."

Other great sounding and highly affordable products from Monarchy include a Zero Feedback Power Amp, the SM-70, and a high power SE-100 single-ended amp. Another 'bang for the buck' product is the Model 33 DAC plus line amp. Monarchy believes a DAC optimized for 16-bit reproduction is still the best DAC for this format. A bassoonist from St Louis Symphony Orchestra enthusiastically agrees. While the DIP 24/96 is marketed exclusively through Audio Advisor, Monarchy sells other products factory direct.
