"Cherry USB" ---- Maraschino USB to SPDIF converter
« on: 29 Sep 2017, 11:19 pm »
We just built our first production USB to SPDIF converter.  This uses a CMedia chip, and it's plug-and-play (driver installation not necessary) for modern Windows and Mac PCs.  It supports up to 192k/24 PCM streams.  Most decent "media player" SW (like JRiver) can be used to convert DSD to high rate PCM for optimal playback on the DAC DAC.  Upstream (PC decode) MQA playback is also supported.  We use this USB converter for all our computer audio demos.  The case slimmer (a little more than an inch tall), but has the same footprint as Stereo Maraschino, 60V 1kW Maraschino Power Supplies, DAC DACs, and our new Linear Power Supply for Maraschino, for easy "stacking".  This USB converter also has anti-vibration Sorbothane feet.  List price will be $390, but price for DAC DAC owners is $100 less.  Thanks for taking a look!

So USB powered (as opposed to having its own power supply)?  Do you take any steps to reduce USB noise within this unit?  Or is it just a straight pass-through of the USB signal?

Thanks,  -dB

No need to clean anything up.  The SPDIF is reclocked in the DAC DAC.  Performance tests indicate 100% data accuracy.

Powered from USB, so no external power supply required.

Definitely, especially if you've been through the kind experience I had.  Driver installation nightmare plus couldn't get it to work and wound up returning it.  The Cherry USB is easy to use and we've never had a problem with dropouts (like with some other converters).  Thanks for your kind post.

Just to clarify, the Cherry USB Converter has a transformer isolated output.  All happy customers that have the pilot run units!
