Design The Canadian-made Moon i-1 is a full-functioned integrated amplifier with remote control. It has six line-level inputs—including one front-mounted mini-jack for personal media players—and a headphone jack. It also has a RS-232 port for fully bidirectional feedback in custom-installed systems and firmware updates, as well as an infrared input for external control. The remote control is designed to control other Simaudio products (eg, CD players) as well. The i-1 has a separate Preamp Out to enable its preamp section to drive external power amplifiers. The Moon i-1 is claimed to output 50Wpc into 8 ohms or 100Wpc into 4 ohms, and the bipolar output devices are biased into providing class-A output up to 5W. Its oversize power supply uses a custom-designed toroidal transformer—the largest Ive ever seen in an integrated amp. Looking at it gave me a hankering for a Chicago-style deep-dish pizza. The circuit-board traces, of pure copper with gold plating, are designed for low-impedance characteristics. The all-aluminum case is rigidly built to minimize external vibrations, but there are no external heatsinks—the i-1 is designed to be left on at all times for optimal performance. Simaudio claims that its low operating temperature will make it last longer. I left my review sample on all the time; the chassis barely rose above room temperature. Sound The i-1 had the Simaudio family sound: deep, rich bass; sweetly extended highs; and midrange clarity with exceptional transparency and detail while never sounding sterile or cold. Essentially, in all their current designs, Simaudio has found a way to deliver the strengths of solid-state -- wide bandwidth, extreme neutrality, exceptional clarity, topnotch detail -- with enough richness and texture that their products sound musical, inviting, and nonfatiguing The Moon unraveled inner-midrange detail unlike any piece of electronics Ive heard in its price range. With all recordings, the high frequencies were silky, silvery, and extended, with an effervescent sheen reminiscent of more expensive solid-state electronics, but with the organic liquidity of expensive tube gear.
