After a week of serious listening I can say that GR is really a digital free device.
I can play music for hours without any fatigue with incredible flow and musicality.
The stage is 3D and completely not connected to the speakers.
I would say that GR is a level up in comparison to MR SE...
My All Time Favorite Preamp is Thomas Mayer 10Y pre.Much better than Soulution 721 in my system which I owned for few years.I currently use it with Wavac Ta-805m and Accuphase A-250 mono amps.
I also after having a few nice dacs like:Asthetics Pandora,Ayon s10 signature,Bricasti M1SE,
Dcs Rossini,Gryphon Kalliope have ended with the DSD-MR SE.
I am very happy with my end dac:).
