Mostly it depends on the DAC.
If you have one that ignores the external clock it is totally silly.
Thanks for the answers.
My DAC is being fed by the Clock and it made a noticeable difference on it, but not much on the upper parts of the digital chain. It seems that the further from the DAC, the smaller the impact of a clock.
I will watch Hans SMS-200 Ultra Neo video again. Thanks. I don't remember him talking about this subject in particular.
“Does it really make a noticeable difference?”
The answer to your question is emphatically YES! But you must use a very high quality external Master Clock to hear appreciable improvements.The BNC clock cable quality also matters. If your DAC or Streamer can accept a 10MHz external clock input, it is absolutely worth experimenting. I don’t own SMS-200 but my experience with Aurender N20 fed by external master clock was quite an eye opener. Inspired by this revelation, I am now putting together pieces to try a fully tricked out sNH-10G switch with external master clock and later plan to add Aurender N30SA.
Once you hear a system with a high quality master clock, you will not go back!
Thanks for posting the video. Hans nailed it. But man, he missed the opportunity to kill two birds with one stone, he could have easily asked SOtM to send the switch with external master clock input :-)
Thanks for your post and clarification. I keep forgetting majority of folks still using USB or AES/SPDIF to connect their streamer and DAC. I have gone all Ethernet and couldn’t be any happier.
@dgarretson That sounds like an amazing setup.
@plga What was your final decision? I am in the same boat as you. I bought the SOtM sMS-200 ultra Neo 2 years ago with no clock input. I am considering adding a 10 MHz external master clock which means I need to replace the Ultra Neo and buy a DAC with clock input. I am also looking at the Gustard R26 streamer / DAC as well.
Well, SOtM USA quoted me $350 for the aditional master clock input and I won’t do it. Originally was $200 when I bough the SMS-200 Ultra Neo.
My experience is that the closer the clock to the DAC the more impact it makes. So, I use the three outputs of the master clock for the DAC, the DDC and the Uptone ER.
I think there are better ways to improve sound for the money as I would also need to spend on a clock with more outputs.
$350 + a new clock is too much.
Well, I think it is a bit excessive but they have to open up your unit, make sure they do not cause any damage, add the clock input, then close up right? So it should cost more than $200 but that's almost double. I will pay the $350 or get another Ultra Neo with all the bells and whistles (Special Edition). I plan to get a clock with 3 or more outputs. Thanks so much for the info!
@dgarretson Someone made me an offer I couldn't refuse. I just purchased the Esoteric Grandioso D1.
@plga I reached out to both Magna Hifi and SOtM USA to investigate adding a clock input to the sms-200. I just checked my receipt and I did add every option except the clock input. Do you think I still need the Audio-GD DI-20HE?
Well, the Audio-GD DI-20HE is not a reclocker, it converts the digital signal to a different one that's easier for the DAC to process.
I would say it depends on how good is the USB input of your DAC.
I'm almost sure it will improve the sound quality, but it would be great if you could try one or any other DDC with your DAC before deciding.
@zeusodin The Musician Pisces or Leo will both reclock and allow you to take advantage of your DAC’s XLR input (or i2S if your DAC has that input) so it’s like two benefits in one. The Leo has a better clock and also has an SPDIF input that is nice if you have a CD transport, so those might be some things to consider.
