Gryphon Diablo 300 vs Vitus RI-101

They always sound better if they cost more.

They always sound better if they cost more.

I think most audiophiles do not believe this. I wouldn’t have gotten the JC1 if that were the case. If there are other int_amp/amp you believe can best these brands, please share.
The JC1 has 132000 microfarad cap reserve (at each side), and can do 135 amp peak, with damping factor > 1200. 25w of class A (at 8 ohm, so prob 50w at 4 ohm) to start, going 1200w stable at 2 ohm. If you have electrostatic, this is the top amp without equal I believe.

But there are different aspects of performance I’d like to explore. The grain free texture in high and mid, the soundstage, the immediacy related to PRAT. A burmester 911 has 160000 μF caps, and has damping factor> 10000 supposedly. Soulution 711 has 1,000,000 μF cap reserve. Same thing with the Vitus... so I just want to explore more with these brands by getting their entry level gears. And these are within the price range.

Personally I do not think Levinson amp being so much more expensive, is worth it for example. I have nothing against them, I just do not ascribe to their corporate believes.

Your current PS Audio DirectStream DAC, PS Audio BHK preamp & Parasound Halo JC1 monoblock amps are fine and good enough for your Focal Sopra 2. The Parasound Halo JC1 is on a fuller warmer side of neutral and I think is a good match for your Focal Sopra 2 speakers since the Focal is an analytical sounding speakers and would be better off with a full warmer sounding amp & preamp like the Parasound Halo JC1 and the PS Audio BHK preamp, which is a hybrid design with tube input & SS output stages.

But that being said, between the Gryphon Diablo 300 & Vitus RI-101 if I were you I would probably go with the Vitus for the Focal Sopra since the Focal is analytical sounding speaker and the Gryphon Diablo is somewhat neutral whereas Vitus in general imo would have more fuller warmer sound in comparison to the Gryphon. So I think the Vitus would be better match for your Focal Sopra speakers.  

I would pair your Focal Sopra speakers with full warm sounding electronics If I were you.

Other electronics that will be a great match for your Focal speakers is Naim Audio. Look for some Naim separates. But if you go with Naim, you will have to go all the way Naim, starting from a digital front end source component (Naim digital streamer/DAC), linestage analog preamp & power amp. 
If you decide to go with Naim electronics I highly recommend that you use Naim's proprietary DIN connections (DIN cables) to connect between Naim components or electronics in order to optimize sound quality and will sound quite a bit better than using its RCA connections (cables) to connect between Naim electronics. Naim always highly recommends using its proprietary DIN connections. That's why you will have to all the way Naim using Naim streamer/DAC, preamp & amp and use DIN. DIN is basically a Naim's simplified version of XLR balanced analog audio connectors. 

Naim makes excellent highly musical sounding streamer/DAC especially their ND 555 streamer/DAC paired with external 555 PS DR external power supply unit. They are expensive though. 

Naim electronics sounding full body, warm (I would characterize it as intoxicated warmth not like tubey syrupy type of warmth) very natural organic sound yet excel in PRAT without straining or sounded forced. Very rhythmic with great pace speed & timing and has musical drive. very musically engaging and involving. 
I highly recommend Naim separates for your Focal Sopra 2. Actually your Focal Sopra 2 were voiced and tuned using Naim electronics since the Focal and Naim merged some few years ago. They would have good synergy together.

Thanks for the suggestions. I actually was looking at naim, as I know sopra was voiced with them. But their 500 amp (never mind their statement stuff) is pretty pricy, plus they really have no present in US, and nobody have their gears.
The other made-in-US option I think is good would be pass labs, maybe their x260.8.... 

hello; I currently have Focal Sopra 2; I have a PS Audio Directstream (had the A21 Halo/JC2 combo, BHK and also LS27 so similar hardware experience as you) and currently run a luxman m900u amp (c900u preamp inbound); Previous to the Sopra 2’s I had Dynaudio Contour 60s; The Lux has a very "alive" and very transparent presence about it;
I personally do not like the synergy with the Sopra 2 and will be moving on from the Focals; With the Contour 60’s the tone and overall sound quality was far superior to my ears; I did a ton of research about the Gryphon Diablo 300 (was very close to acquiring) and, on paper, it seems the Focal synergy would be better, or perhaps the Luxman 590 AXii Class A integrated.

One thing I noted with the Sopra 2’s; I was surprised to find them about as efficient as my DYn 60’s; on paper that should not have been, but it’s what i’m experiencing. It actually seems that they like MORE power than the 60’s; go figure.

I would include the class A stuff from Pass Labs in your hunt; I had an XA30.5 and it was a wonderful amp on the Dyn 60’s. a velvety beautiful mid-range excellent dimensional aspects, sweet treble, that I think would have been a better match on the Sopra 2s; With the DSD/BHK and a Pass XA30.8 I think there is potentially excellent synergy;
You did mention 260.8 monoblocks, and they have about 35watts in class A, so that might be better...you already have monos, so you probably have stands too :)

I have only read this, and so it’s mere conjecture, but Naim might be too thin with the Sopra 2’s.
Another up and comer to check out would be the Hegel H590. Reported to be very powerful and smooth, yet highly resolving.

Please describe your acoustic and music characteristics; Room dimensions, listening position, spacing, damping (bare walls/floor heavy carpet...), genre of music, preferred listening volume...etc.

Also, what cables are you using, IC's, speakers, power?
Have fun!
