Master Clock for the SOtM SMS-200 Ultra Neo SE

Hi guys

I have the SOtM SMS-200 Ultra Neo SE in a rig with a very well treated digital signal. It sounds very nice, but it doesn't have a Master Clock input because I did not wanted to pay that aditional cost back then (now I kind of regret it as I have a Master Clock).


Has anyone of you tried this device with and without a Master Clock feeding it? Does it really make a noticeable difference? My experience has been that the further the device from the DAC, the less impact the Master Clock makes. The biggest impact is feeding the DAC. I have it also feeding a DDC before the DAC and the Uptone ER and I don't find a big difference, mostly on the ER.


​Please answer if you had a real listening experience. I don't want to start a technical debate. 


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!

I have the Special Edition without clock input as it was an open unit with lower price.

Be sure to get it with clock input.

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.

I think so too.  What DDC and DAC are you using and what connection between them?

I have no DDC as of yet. I am looking at Denafrips Iris, Musician Pisces, and Singxer SU-6. Others? I am using a 10 year old April Music Eximus DP1. Obviously, it has no clock input.

My DAC is the Audio-GD HE-7 and my DDC is the Audio-GD DI-20. The connection between them is I2S.

For a top notch DDC I would recommend Audio-GD DI-20HE over the other ones mentioned above.
