I have the old Gryphon Diablo 2 x 250 watts 8 ohms
The DS DAC volume level is 100
I have tried both connections, my balanced cable is Transparent ultra mm2 , my rca cable is Ansuz ceramic. There is not much difference.
I have tried my Raidho speakers with Exposure MCX monoblocks ( 2 x 300 watts 8 ohm, 2 x 600 watts 4 ohm ) . Exposure MCX made considerable difference in terms of speaker control. MCX has also more air . etc. So i decided to replace my amplifier with some more powerfull amplifier.
Gryphon Diablo is more powerfull compare to a lots of other amplifiers but i think its not enough for Raidho D2.1
