Gryphon Diablo 300 vs Vitus RI-101

This is a great thread and is very useful for someone such as myself looking at a 2nd tier SS integrated.  This is a follow up question re. Vitus.  Is it a waste to buy an SIA-025 (Mark 1 or 2) if I’m never going to use the low output class A output?  Would I be better off with an RI-101 or RS unit?

 It does not respond much to source or cable changes.

?! My D300 responded very well to a better power cord.

I preferred the Diablo 300 over the Vitus RI101mkII, better looking too.

I have to agree with @supermerio, i owned the Diablo 300 for a year and the Vitus SIA-025 Mk2 for more than a year and recently demoed a Jadis DA88S equiped with 8 KT120s.

The Jadis easily outperformed both the Gryphon and the Vitus in my system.

This was a big surprise for me even if i still like my SIA-025 Mk2.

I guess it is system dependent but with my speakers tubes amps bring things to a whole new level and i have demoed very expensive SS amps in the past.

@thieliste Yes it is system dependent. Thiel speakers can sound a bit bright and aggressive with the ”wrong” amp.

Both Diablo 300 and Vitus 101mkII are great sounding amps….but perhaps not the best match with Thiel speakers.
