The SIA-025 as a lower powered, sweet sounding class A amp is quite a different beast from the RI-101 which is a 300 watts class AB brute. (But still excellent) How either of these may compare to Gryphon I will leave to others that have heard both. I doubt you could go wrong with any of these choices however, as they are all top echelon gear.
Vitus versus Gryphon
In general, What’s distinct differences and similarities between Vitus integrates amps and Gryphon?
Perhaps, Vitus ri-101 and Gryphon Diablo-120.
Thank you
