For sale is a MINT condition Mutec MC-3+ USB Smart Clock Silver unit left. I had two.

This pair was bought from Markertek in late May, shipped June and was used no more that 20 hours in a backup system as a USB converter daisy chained to the other one as a reclocker. This is by far the best USB sound I've heard in this system. You can also use it to reclock SPDIF, which people have been doing to output signals from their Lynx or Rednet, taking it to the very next level. Versatile unit can be used to convert from USB to SPDIF/'AES via coax or BNC, and convert DSD to PCM in the hardware and with plenty of settings to play with.

If there are any questions, please ask. Comes everything it came with ( original packaging, accessories and manual) as there were set up and compared, then stored. These units need to be broken in due to low use.

Price new: $1099.

Asking $xxx + shipping / fees. Paypal add 3%.
