  1. you want re clocking. The mutec will get a time source from the frequency of the audio in. It regenerates that entirely from its internal high quality clock. The only time you want a clock in reference used with the Mutec is when you use their even higher quality clock source or are cascading Mutecs as some do.
  2. Hi Beolab. Looks right. SPDIF into and out of the Mutec will reclock that digital audio feed before your DAC. On my Mytek DAC (I use AES Digital) but that’s not so important, when I feed the DAC also with the word clock and toggle between internal clock and ext clock I hear almost no difference. A lot will depend on how good your DAC clock is
  3. I borrowed my Mutec from a dealer in the UK and played with it to see if the expense improved the SQ enough.. I guess this is the only route to see if this really adds value on SQ and also improves your ability with DSD. I ironically still use my Sonos streamer most of the time as it is server less and just works.. Despite paying for Roon. Having a Roon Rock on a mini PC, a MicroRenu and linear PSU. I find it all a bit of a faff. The Roon chain does sound better. I just need to crack the simplicity part. Plus I have no local music stored (well I do, but dont use it)..
  4. The process turns off most of the LED’s and I have been able to do it with mine. I recall that I then forget how to turn them back on! Needed as I use mine as a source switcher between a Sonos (Spdif) streamer that I just always come back to for ease of use and then a roon based more complicated USB streamer Glad you love your unit. Out of interest - how do you feed your DAC from the MUTEC? AES?
  5. Hi @guitardave - I have both a Sonos in my system and a Roon setup with a MicroRendu streamer. Sonos is fed SPDIF into a reclocker (MUTEC) and the Rendu feeds USB into the MUTEC.. That in turn feeds AES into my DAC. I like you have been thinking the Sonos isnt very HiFi.. But the UX is really good. I find Roon frustrating more than easy, and it requires a server where Sonos doesnt.. I have been thinking of a streamer that is server less as I do not want the faff.. Right now, I cannot tell a huge SQ difference between the paths... The Sonos stays because it just works..
  6. Thanks for the thread share on Roon labs @wklie.. Perhaps this platform is beefy enough (although I doubt the Roon guys could take advantage of the GPU with all those cores.. I understand there isnt much in it for them.. My small frustration is that my Sonos ZP80 'streamer' does all of the platform aspects I need (as I tend to stream all of my music, rather than local), yet for 'HiFi' reasons I have also a Roon Core setup and MicroRendu streamer with another PSU. That was bought for USB hi res and MQA streaming via USB.. I added a Mutec USB and SPDIF/AES re-clocker and my Mytek DAC seems to prefer AES in.. Hence in tests, I hear little difference between a 'complicated chain' my Roon Core is a Rock on a micro PC, and my not very HiFi Sonos (with a nice UX... Hence I am getting more tempted to consider higher end streamers (I noted you work for Lumin ;-)
  7. Just seen this announced and seems to be a beefy potential platform with much lower cost than a NUC... $99 announced price https://devblogs.nvidia.com/jetson-nano-ai-computing/ I have none of the software skills to make this work unfortunately.
  8. Hi - it wasn’t that clear if all of this change was the different mains source vs insertion of the Mutec into your system. Could you clarify please?
  9. Hi - This will be my fourth Windsor show - and it is always a great event for High-End.. Wondering if anyone else on this forum is going? Cheers Simon
  10. Has anyone experimented with using the Mutec clock out to feed your DAC as well as feed it audio (to sync them?) I tried A/B tests on my Brooklyn DAC (internal clock that Mtyek recommend), using the sync on audio (i.e. clock rate of the stream via AES in my case (from the Mutec) and also 'ext' clock on the DAC - which uses the word clock output from the Mutec via a BNC cable to the Mytek ext clock in.. Cannot say I heard much difference - or at least very subtle.. Guessing the Mytek isn't wanting to use an Ext clock, isn't optimised for it, or the clock quality in the Mutec is similar to the Mytek.. Perhaps others have tried their REF 10 feeding the Mutec and their DAC? Simon
  11. Hi - I use both with my Brooklyn DAC. USB from a microrendu and spdif from a Sonos zp80 streamer (still one of the easiest to use systems for me). AES balanced to the DAC now. I haven’t been able to do a detailed comparison between inputs as the sources are different. But they both are better than into the DAC direct. USB allows me to stream MQA etc.
  12. Thank you. I had assumed as I cannot find any of the settings for upscaling in my Roon instance but sure I had seen it when it was running as an app on my Mac Mini as the core. My rock is a rebuilt micro pc without a lot of horsepower.
  13. I have some more research to do it seems as I couldn't find any of the DSP settings in Roon on my Rock (I haven't loaded the FFMPEG codecs). I also haven't installed HQP on it.. Not sure how to.. so will have to look into it..
  14. I did some tests today. AES in from my Mutec reclocker and using the WCK option from the same Mutec. So basically having the DAC use IN (as in input - Not INT) or WCK (external clock). You’d think there wouldn’t be much difference considering the clock source is basically the same - the Mutec well with a quick and easy A/B from the listening position the focus is more pinpoint with the WCK option set. Track depending I found and the bass is slightly different in each. Overall we are talking subtle changes. Im not using the USB in on my Mytek as found the Mutec brought benefits (as it should for half the price of the DAC.
