Interestingly, that is how i would describe Gryphon. To me, i found it had an intensity of sweetness/humanness that i preferred over the Boulder.
I was beguiled by much of the control, power, linearity, etc of the mighty Boulder 2060...but i could see why some (not me) might say it also came across as quite 'clean'. NOTE: i did NOT feel that way, but i did at least appreciate that i could see why some might feel otherwise.
The Gryphon on the other hand provides same/comparable graceful authority, linearity, extension, detail...yet somehow a 'touch' of sweetness during intense violin attacks, etc which i really, really enjoy...and to me completely avoids any notion of that 'Boulder clean'. Is Gryphon 'right'? Heck if i know...all i do know is i enjoy more music on Gryphon than anything i've heard before.
I am sure with a few tweaks to my system here and there, it would sing beautifully with the mighty Boulder...i am just fortunate that i dont have to because the Gryphon is just how i enjoy my music.
