Simaudio MOON 350P Preamplifier
MOON 350P Preamplifier - Front
The Neo 350P is available with two options, which can be included at the time of purchase or added later on. A high-performance and very versatile DAC is offered for connectivity to your latest devices: a computer, DVD/Blu-Ray player or an iPod docking station. If you have a love for spinning your cherished collection of vinyl, a fully-configurable MC/MM phono stage is also available.
Of course, key features you'd expect in a MOON Neo Series product are present such as SimLink, 12V trigger, RS-232 and IR ports for custom-install environments.
The USB input on the MOON 350P's optional DAC accepts a digital audio signal of up to 16-bits/48kHz. This is the native specification of the USB input. However, if you require a higher sampling rate, there are ways to achieve this with the 350P.
Rather than including a USB input for sampling rates exceeeding 48kHz, we opted to provide the best possible power supply, D/A converter and analog stage in the MOON 350P at this price level. Also, keep in mind that USB wasnt originally intended for use with hi-resolution audio; there are latency issues which compromise sound quality (i.e. jitter and phase errors, etc.). These could be minimized through dedicated costly circuitry, but this would significantly drive up the cost of the 350P without improving the sonic performance on any of the other inputs.
If you intend to use the MOON 350Ps USB input, its very likely that your computer is a data source for music. Today most computers with a built-in sound card will have either an S/PDIF (RCA connector) or Toslink (optical connector) digital audio output, thus eliminating the need for a USB input on the 350P. Furthermore, if youre committed to getting the most out of the music stored on your computer, then in all likelihood you have installed an after-market soundcard in your computer. Virtually all of these soundcards have at least one S/PDIF, Optical or AES/EBU (XLR connector) digital output. At this point, USB connectivity becomes irrelevant. The USB input is there for convenience as opposed to performance.
In the event that you wish to use your
computers USB connection with files greater than 48kHz, there
are several relatively inexpensive after-market products; compact one-box
USB-to-S/PDIF interfaces that will work with USB datastreams up to 24-bit,
all the way up to 192kHz.
