Didn't buy it for the reclocking
musicinprag 13.01.2021
I wanted a USB device with bitperfect ASIO support that could do format conversions to AES. This box absolutely does that. The software is very good, no glitches. It appears to Windows like every other ASIO device I have and it is recognized by all the apps I'm using.

There are a few things I would change about this but none of them are major deals for me.

1. It seems more likely S/PDIF would benefit from reclocking than AES, so I would have preferred if there were two AES XLR outputs rather than one each of input and output. But as it is there's pretty good connectivity here. The back panel is impressive. Just about everything is there.

2. The UI is really nice and dead simple. The menu operation is so well thought-out you almost don't need the manual- which I think is an excellent manual. But I'd like to see some indication of input bit depth, either three LEDs one each for 16/24/32 or one LED that changes color. Some output devices need bit depth set and if you don't know what it is it can be annoying. Bit depth indication would save some time.

3. The device can handle DSD256 over USB. Annoyingly, there is no BNC output for DSD, everything is converted to PCM. I think it would be worth trading one pair of wordclock output jacks for true DSD out over BNC.

The unit feels solid and although the power switch is annoyingly on the back panel, it is extremely positive. It snaps hard on or off and will not bounce. Really nice hardware. Heavy cables so far do not push the unit around.

I don't have any comments on the sound quality yet because that wasn't the main reason I bought it.

Update: the plastic door on the optical S/PDIF output broke off inside the housing the first time I used it. Although it took some time to receive a reply, Mutec stood behind the product and offered to repair/replace it or send me another optical socket. Thomann is also looking into the case. So I'm disappointed about the quality of that socket while the rest of the box has been great, and I'm happy with the concern and support of Mutec and Thomann.

A very versatile and effective digital device
Anonymous 23.03.2017
I bought the Mutec for use with my digital, home Hi-fi system. I use a Mac mini computer as a server and have added a Sonore Microrendu connected to my home network by ethernet and using Roon on my Mac as the music player. The Microrendu outputs via USB to a Hegel 160 amplifier's USB input.

I wanted to see if the Mutec USB would improve the sound of my system by converting the USB signal to SPDIF but also because of its reclocking and abilities to reduce jitter. I am very glad that I tried it because it has made a big difference to the overall quality of the sound of my system.

What is more, the Mutec is flexible enough for it to adapt to any digital system that I may change over too. People even use them to improve the sound of the digital inputs to very expensive Devialet amps!

Believe all the good press about this little wonder and snap one up now before Stirling drops even further against the Euro!

a well-performing recommendation
Hieronymus 23.12.2017
I use it as a USB interface while PC as source, and a bridge delivering from CD transport which has a bnc-wck sync function. Additionally, I use an Antelope OCX HD as wck sync source all over my system, enhanced by a Rb 10MHz generator made in US for telecom use. Both ways are quite well and sound more musical, more dense and more 3D. Good at re-clock and re-shape, Mutec MC 3+ delivers a wide sound stage and precise localization of individual sounds.

Power issues
Eddiechilli 11.02.2019
The unit is spewed for USB 2.0. I wrote to mutes when the deceive kept disappearing from the midi manager on Mac Mini High Sierra 10.13. Mutec wrote back to say try USB 3.0 the USB input might not be getting enough power.

Why a device that takes mains input should be dependent on rubbish usb power from an upstream Mac with crappy amps I just don?t get.

Now it looks like I will need to buy a new Mac.
