Hi Tom.  I went down the same path as you in replacing a Project ClayX Giesmann clock with a Mutec REF10 (not the SE120) over a year ago and I've not experienced any issues.  I would perhaps try swapping out the 75ohm cable ?  The Giesmann is supplied as either a Sine Wave or Square wave version as I recall which needs to be nominated at time of order placement.  The Mutec is Square Wave output only so are you certain you have the right cable installed for a Square Wave output to the ER?

 

Those more knowledgeable than me will be able to point you in the right direction I'm sure.

Alex's suggestion is worth checking out.  My previous power amp, a Luxman L58A would momentarily cause my house lights to dip when it powered up.  It had a substantial power transformer and the initial current inrush would cause a momentary voltage drop of probably only a few milliseconds but enough to notice.  Fortunately it never caused any issues with my audio gear at the time but the ER as Alex points out is not tolerant to even a momentary voltage drop when the ER external clock input is used.  The Mutec Ref10 might also be sensitive to the same issue.

 

BTW:  Given your investment in the ER and now the Mutec Ref 10, it's worthwhile sourcing a really good quality square wave cable for the Mutec + ER connection.  Perhaps Alex can also assist in that regard?

Hi Tom.  If you haven't done so already this contribution from John Swenson might help with some background on the clock cable topic
