I've been using the Mutec MC-3+ for about a week and there's a significant improvement in my digital playback. I have a PS Audio PWT outputting AES/EBU and a Blusound Node2i using SPDIF coax out.
I've found that the Node2i doesn't output a very good quality stream. After adding an iFi iPurifier (reclocker) there was a noticeable SQ improvement. Now that I'm using the MC-3+ in reclock mode, I have no immediate need to upgrade my streamer or DAC. Music has more weight, detail, and depth. I haven't played a CD yet as I've been enjoying a much improved Qobuz this week. I don't know how much improvement a 10 MHz word clock would add to home audio. It might depend on the quality of the dac and how revealing a system is.
