Gryphon Diablo 300 vs Vitus RI-101

   So I've been itching to upgrade my amp. I currently have: PS audio Directstream -> PS BHK preamp -> parasound JC1 -> Focal Sopra 2.
    I narrow down to these 2 candidates. Any one with experience with both int amps can comment on them?Thanks!!!
I understand. But even with dealerships, having completely different system setup/wires/frontend, it's not possible to discern the turn nature of an equipment with just an afternoon.
If someone have had experience with both (or the older RI-100), that'd be very valuable opinion to me.

I know the Vitus Sig class class A pieces are leaning to the warm side of the equation comparing to Gryphon. But the new 101, being class A/B, and had bump up the cap reserve to 216000, might just deliver more PRAT than gryphon. I don't know...
Is there a reason you want to replace the Pre-amp too? The PS Audio should be a pretty capable pre-amp. 
I’ve been itching to upgrade my amp.

What is it that you don’t like about the JC1’s (in high class-A) mode, these are great amps for your speakers which are a bit of an evil load from 60hz to 150hz, similar to the 3’s it’s said.

I would say keep it the JC1’s and change the preamp to a tube or something if you want a bit of tonal change.

I don't agree with George. I think given your PS Audio setup, a more obvious next step would be the BHK 300 mono blocks, assuming you already like the house sound with the pre-amp and DAC.
Frankly I have no complaints about the JC1 or the bhk preamp(it replaced a audio research ls27). But I'm just always curious about the uber top level neutral SS amp and what they have to offer; burmester, dagnostino, constellation, vitus, gryphon, dartzeel, soulution.... Nothing again class A warm sounding amp, but I want to try the highend ultra fast yet relaxing sound. The directstream is already smooth sounding, the sopra itself is smooth nothing like old focal forward sound. So I figure to get the best out of this chain is the fastest neutral amp I can get my hands on. And when looking at these top level brands, the 1 piece integrated is pretty good deal given their preamp separate pricing.

I wouldn't mind doing a 60k constellation preamp with a pair of dagostino momentum....when I win the lottery. But meanwhile, I want to see if I can get an int amp to test and see how it compares to my bhk+JC1.
