Esoteric Question - is the new Grandioso K1x that much better than the Esoteric K-01xd ?

I have been using Esoteric K-01XD with G-02X master clock since past 3-4 days. The improvement is definitely not subtle. It is not going to make jaw dropping change: that is not what it is meant. Simple way of summarizing is that it makes good change in every spectrum: Adds a little sparkle to highs, little sweetness in the mids and the lows are more deep, controlled and tight. There was increase in the soundstage (vertical more than wide). A sense of air around instruments also makes this very special. It makes your DAC get better by at least 15-20%. I have not heard K1X but I was told by dealer that K1X was better than K-01XD + G-02X. Not sure about K-01XD + G-01X (more expensive masterclock) compared to K1X. 

Of note, I am using same masterclock with aurender N20 and the improvement is big. I am waiting on new masterclock BNC cables to arrive to use it with etheregen switch and SOTM Snh-10g. 

I have k-01xd which is CD player with dac. N-01xd is network player with streamer (which is not what I have). 
with regard to network switch, yes, having 2-3 switches makes it better. I had tried with single and then went up with benefit each step up. Have router > sotm snh 10-g > etheregen via fiber optic > English electric 8s > ENO acoustics
