Emm Labs CDSA 'X' upgrade

My friend in Hong Kong bought a new CDSA SE 4 weeks ago. It's still labelled as CDSA SE and doesn't have any indication of whether it has the new circuit board or not.

Is it a remaining stock of CDSA SE or is it already installed with the new 'X' board?

Will there be a formal 'CDSA X' soon?

Thanks for your advice in advance.

Rgs92, Thanks!

I will remind my friend to check the back of his CDSA SE.

So the upgraded X version can't have output level adjustment?

I wonder whether EMM Labs will formally launch a CDSA X since the internal circuit board changes & sonic improvement are not trivial.

Thanks Rgs92, have you compared your CDSA SE with X upgrade to Playback MPS-5 or EMM Labs XDS-1 or TDS1+DAC2?

Even if I install the X upgrade on an used CDSA SE , the total cost will be similar to a Playback MPS-5.

Thanks for your advice in advance!
