Mutec MC-3+ USB

[ogs]

I don't think that what's been written is correct. When we'd use the Mutec we'd connect it to a Devialet digital input, either a S/PDIF RCA or AES/EBU (I'd prefer the latter). The Devialet will extract the clock signal from the input data stream -unless- it has a ASRC (asynchronous sample rate converter) or if it buffers and reclocks the input signal. In these cases it'll throw away the embedded clock signal from it. So this ASRC/reclocking is not preferred if we'd like to profit from a high quality wordclock. After all we'd want the Devialet to use the HQ clock and not it's lesser quality own.

Since the Devialet's upsample each and every input to 384kHz/40 bit (the internal sample rate used for DSP processing) I'm not sure if any HQ clock will have any/much effect because I think it will use it's own internal masterclock for the sample rate conversion.

Those who'd want to be sure would have to ask Devialet how an incoming digital signal is processed.

Hi Antoine
I understand what you are suggesting, but there is no re-clocker in the Devialet. I've asked them this Q too. Everything is upsampled , yes, but not re-clocked. I'd suggest that if there was some sort of re-clocking going on inside the Devialet the impact of the Mutec would be far smaller. The difference would then be clock quality and/or re-sampler implementation. Maybe the AES input of the Devialet is "good enough" (and it certainly is very good) although I think a word clock input on a Devialet amp could improve sound quality. As would an i2s input...
