Vitus versus Gryphon

The Vitus was so good, I could not even leave my listening chair with many attempts.

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.

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.

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.

ilisten mostly in
a/b as i like the brighter and more
aggressive type of presentation it brings to the
music i listen to, it livens up the leading edges of
of guitars,trumphets, violins etc. If iwant a more 
intimate vocal and liquid presentation; i switch to
class a.

It was actually a choice between sia 025 or the r100
seperates. I did have a little bit of remourse as i should
have gone to seperates since i heard it has a
much better slam and a bit lower noise floor.

I have owned the Diablo 300 for a year and can tell you it was a very bad match for my Thiel CS 3.7 speakers.

If your speakers tend to be bright than don’t buy the Diablo 300 you will regret it as i did.

Vitus is much more musical, liquid sounding and has a lot of finesse as opposed to the Diablo 300.

Buy Gryphon only if your speakers are very smooth like Sonus Faber.

I now went the Vitus route with an SIA-025 Mk2 and am very happy.
