Retail pricing may vary from one country to another as a result of foreign currency exchange rates, overseas shipping costs, value added taxes (VAT), import duties, tarriffs and other import costs.

There are two ways to accomplish this. You may use either the "mail-in" product registration card found in the box of your brand new Simaudio MOON component or use our on-line product registration form 

You must register your new product with Simaudio Ltd. within thirty (30) days of the purchase date in order to receive the extended warranty as outlined on the warranty certificate enclosed with your product.

The warranty is NOT transferable unless the component is purchased from an authorized Simaudio MOON retailer. Please contact our sales office by email sales@simaudio.com for further information.

We're a manufacturer and normally operate from Monday to Friday. Consequently, emails that are sent to us on the weekend may not be read until Monday. As well, there are several different people that handle the emails sent to the various addresses and they are not always at their computers (or even in the office for that matter).

In any event, we always reply to every email as promptly as possible so please be patient.

Currently, not all of reviews are available from this site.   However, the plan is to make most of them available in the near future.

Provided that you have a high-speed internet connection or a fair amount of patience, they can be dowloaded from this site in Adobe PDF format.   Simply visit the literature page on this site.   We've taken the liberty of including the file size for each piece of literature to assist in determining your download time.

If downloading literature is not an option for you, simply email us your request and we'll put something in the mail as soon as possible.   Please keep in mind that by the using postal service, you may not receive the literature for several weeks.

In a word, YES.   Simaudio components use various electronic devices (such as JFETs, MOSFETs and BiPolars) which require several days of constant current to fully stabilize. This is especially true for digitally based audio components where thermal stability is absolutely crucial. As a result, leaving your Simaudio component "powered on" all the time will yield optimal sonic performance. Preamplifiers and Integrated Amplifiers, CD & DVD Players, and Home Theater Processors may be switched into "standby" mode when not in use without compromising performance; When in "Standby" mode, all critical internal electronic parts are powered up to maintain optimal performance. Simaudio components use as little as 18 watts and no more than 60 watts at idle.

These times imply constant operation.   If they seem a bit excessive, the reasons are as follows: Our components are solid-state and use certain devices which require a fair amount of time to stabilize and reach optimal performance (see previous question).   As well, since preamplifiers deal with much lower voltages and we use no buffering/coupling/filtering capacitors in the signal path, they require more "Break-in" time than other components.

The "On/Off power switch" controls the AC main feed and should be left on at all times.   The "reset button" is a "soft" power up switch and is the actual mechanism for powering up your amplifier.

There's one pair (2) of RCA inputs per channel multiplied by 2 channels, resulting in a total of 4 inputs.   One input on each of the channels is clearly marked "+" and the other is "-".   Normally you should use the "+" inputs and leave the "dummy" terminators inserted into the "-" inputs.   However, in the event that your preamplifier inverts phase, as is the case with certain preamplifiers, then you should use the "-" inputs and "dummy" terminate the "+" inputs.

YES.   Removing them may substantially increase the amount of noise introduced into the audio signal.   In the event that you're operating in Balanced mode (via XLR connectors),   please Read the next question.  

When operating a Simaudio amplifier in balanced mode, the   "dummy"   RCA terminators MUST BE REMOVED from the single ended RCA inputs on the rear of the amplifier.

A customized "Y-cable" adapter is required.   Please contact our service department for further information.

The P-5 uses a discrete gain stage that employs a relay network which selects only one resistor for each individual volume setting.   The clicking is a result of front-end controller cascading through these different relays.  

A brief history on the MOON product line best explains this:   Originally (1996), MOON products were built with a gold-colored oval name-plate inscribed with the "Celeste" name. However, the "Celeste" name was eventually replaced (1997) with "Sim Audio".   In both cases, the faceplates were a pewter color with a "blueish" tint.   As well, the 4 legs were black and their matching pointed cone feet were gold-colored.

In the fall of 1999, we dropped the gold colored "Sim Audio" oval badge and it was replaced with the newer square logo in black and pewter along with the name "MOON" silk-screened onto the faceplate directly below the logo.   The standard faceplate finish is now black with silver legs and black pointed cone feet.   As well, we offer an optional silver finish faceplate that comes with a gold colored logo and gold pointed cone feet.

Earlier MOON components (pre Fall 1999) can have their faceplate and name-plate upgraded to the current style.   Please visit the Factory Upgrades section of the website for pricing details.

YES.   We offer a full-function remote called the FRM.   To keep the price of both the i-3 and i-5 as affordable as possible, we offer a simple remote control (volume, input selection, power on/off) as standard equipment.

Since remote controls generally take a great deal of abuse (ie. falling on the floor), we can only offer a 1 year warranty.   Please be assured that Simaudio remote controls are built to a very high standard so as to withstand a fair amount of abuse.

Aside from the obvious differences in both output power rating and physical appearance, the MOON i-5 offers more refined sonic performance while sacrificing some of the output power that the MOON i-3 delivers.

This type of upgrade is not possible for 2 simple reasons; each MOON Limited Edition model will be produced only 250 times and it would be very cost prohibitive to perform this type of upgrade.

There are two reasons. First, a 720p output signal contains much more data than a 480p signal, resulting in a greater potential for signal degradation and loss. Secondly, all video monitors using DLP, D-ILA, LCD and LCoS technology employ built-in "480p to 720p" scaler circuits. While 720p is higher resolution than 480p, the upconversion process should be done in the display device or by a professional-grade outboard scaler rather than inside the source component.

Since an HDMI cable combines video and audio signals, we strongly feel that it offers a connection of inferior quality. Furthermore, DVI to HDMI adapters are readily available.
