Vitus versus Gryphon

I heard the Gryphon Diablo 300 and T+A PA 3100 HV driving Magico A3 speakers. To my ears the Gryphon Diablo 300 was more detailed and opened compared to the T+A PA 3100 HV. Maybe with different speakers the results would be different.

nasaman,

I owned the Diablo 300 for a while and have listened to the Vitus sia-030 on Focals like I own.   I think that supermerio’s comments above are “dead on” on all counts.  I personally think that if you have neutral speakers that the Vitus sia series is really nice.   If you wants tons of bass control and liveliness the gryphon Diablo is it.  All of them are great imho.  Happy hunting!

A manufacturer that doesn't get much coverage stateside is Grandinote. Take a look at their Shinai or Prestigio integrated amplifiers should lower power output be acceptable. 

I also second @thyname 's recommendation for T+A ,  as well as both of your choices in Vitus / Gryphon.

All the best.

Gryphon and Vitus are both great amps.  I demoed both the Diablo 300 and the RI-101 and liked the RI-101 since it was a bit more organic and fit the sounds signature I have been looking for for a while.  The Diablo was great, just felt that it sounded a bit harsh on some songs. If I was to guess it was from the preamp side not the amp.  I felt the RI-101 combined the full body sound like tube, with clear/crisp highs, and tight controlled bass.  I have never heard anything quite like it.  I can only imagine how good the SIA-30 is.

If you like more forward vocals then you may like the Diablos better.  It’s a total personal preference.  

A very good comparison summary of the Vitus integrateds

Vitus will not give you a "front row" presentation- it is more mid hall , balanced with great depth and tonality. Plenty of slam imo.
I heard the Diablo 300 with Wilson and it was very good..maybe a little dark/earthy. Ultimately, and I know this is pretty petty but I just did not like the looks of the Diablo. Looks cheap with the plastic fascia and oddly shaped. Silly, right?
