Vitus versus Gryphon

Nasaman, congrats on your purchase!

Georgehifi,  you stated above you didn't know the specs of the Vitus products, not sure it's fair to give advice relying on Vitus's website marketing/specs.

While the Diablo 300 is an amazing and powerful integrated, the Vitus products have some of the most enormous power supplies around.

Vitus has a unique sound signature and if he loves the RI-100, then I have absolutely no doubt he would love the RI-101 and up even more.  The SIA-30 has a similar power supply as their Masterpiece 4 piece mono blocks.

The Vitus was so good, I could not even leave my listening chair with many attempts.
I’m A/B’ing XLR and RCA right now. With my type of music, my gear and room, RCA always come out top for the last 15 years but this Vitus.... XLR came out slightly cleaner and more enjoyable and they’re lower grade than the RCA. All cables from Purist Audio. Thanks all

Yet you said this after a couple of days, I must ask why??? if it was so good.

Ri-100.
It’s so impressive... I’m saving up for a bigger one

With 91db speakers you have much more than enough wattage from the ri-100 (300w!!!!). More wattage will bring nothing to the table as they are still bridged amps.

You obviously did not see that later or have no idea, I found they are bridged amps, and when amps are bridged they are not the best into the kind of load OP’s Sonus Faber’s bass loading have.

I have heard as well that balanced inputs, if possible, are the way to go with Vitus given the design.

I do have to say if someone likes tubes but wants the power/bass control of solid state they should try to demo Vitus gear.  Been looking for this kind of sound signature for a while and was shocked the first time I heard the RI-101.

supermerio:  are you running the Vitus in A or A/B mode?  I've heard that the Vitus loses some of it's magic in A/B.  If there is a Vitus dealer out there I'm curious if the RI-101 is better than the SIA-025 or SIA-03 if you have to run the latter in A/B mode.
