"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.

Thanks.  This is a solid product especially useful for the many DAC DAC owners out there!

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!

The converter does look very slick in this housing. Getting mine Tuesday, looking forward to it.

I was using my Asus Xonar STX soundcard (which has a SPDIF out) as a source for my DAC DAC and the sound was good, but after I put the Cherry USB converter in the system I was floored. The sound was so much more clear and precise and the harsh edge (which I was attributing to my recent expensive re-cap of my speakers) was completely gone. I feel that the sound is three times better than it was before and I didn't think that much of an improvement was possible. My wife (who is the ultimate test) even said everything sounds better now. I highly recommend the converter and am so glad I got one.

Here's what I wrote to Tommy:


"Got the USB to SPDIF converter hooked up to my DAC DAC and WOW what a difference. Super details and more smoothness. Nice! More details usually come with a bit of biting harshness, but not this time. Music sounds more realistic, so real sounding that it seems unreal.....guess I'm used to that 'recorded' sound. Anyway, I'm a happy camper."

    I guess I should say I'm a VERY happy camper. No fatigue at higher volumes now. I did not realize how much my sound card was masking the music and giving it an 'edge'. This is quite an advance for my system's sound. Thank you so much!
