Simaudio designs and builds every MOON component in Boucherville, Québec, and the range is easier to read than it first looks. This page explains how the model numbers work, the three ways a MOON system is usually put together, and the questions we are asked most often.
How the numbers work
The first digit tells you where a model sits: the higher it is, the further up the range. A 371 sits below a 641, which sits below a 761, and so on to the 800 level. The last digit marks the generation, so the models ending in 1 are the current designs. Two families carry most of the range. The Compass Collection is the way in: the 371, the 491 and the 461. The North Collection is the upper range, at three levels: the 641 and 681, the 791 and 761, and the 891 and 861.
Three ways to build a MOON system
One box. The 371 is a network player and amplifier together: add loudspeakers and you have a system. If you already have a source you like, an integrated amplifier does the same job without the streamer: the 250i v2, the 341 or the 641.
Two boxes. A network player and preamplifier in one chassis, with a power amplifier in another. The pairs are the 491 with the 461, the 791 with the 761, and the 891 with the 861. Separating the two gives each its own power supply and lets the amplifier be as large as the loudspeakers need.
Adding MOON to a system you have. The 681 is a network player and DAC that brings MOON streaming to an existing amplifier. For records there are four phono preamplifiers, from the 110LP v2 to the 810LP.
The questions we are asked most
Integrated or separates?
An integrated amplifier is one purchase, one shelf and one power cord, and the 641 is a serious amplifier by any measure. Separates make sense when the loudspeakers are demanding, when the room is large, or when you expect to keep moving up, because the preamplifier and the power amplifier can be changed one at a time.
Will it play my records?
Several MOON components have a phono input built in, including the 250i v2 for moving-magnet cartridges and the 791 for both moving-magnet and moving-coil. A separate phono preamplifier is the step up, and it lets us set the loading for your cartridge.
How long is the warranty?
Simaudio covers a new MOON for one year, and for up to ten years once it is registered with them within 30 days of purchase from an authorized retailer. Moving parts such as volume controls, switches and disc mechanisms are covered for three years. We register your MOON with you when it is delivered.
What if I want to move up later?
Simaudio's trade-up program lets you put most or all of what you paid toward a higher model during the first two years. Trading up your MOON works out what yours would be worth.
