Classe CA2300 vs Vitus RS-100


What amp is better? For classic music, for hard rock & metal? How good is Classe 2300 for Sonus fabers, e.g. Stradivari? I've only listened to entry level Vitus amp with Strads and it was great match, but Vitus is a bit expensive and Classe amps are more often met in second hand than Vitus so I'm looking for information, impressions and opinions about.

melbguy1, thanks a lot for your answer!
If you’ve remembered it after listening both amps, how much is sonic difference between RS-100+RL-100 and RI-100?
Aural memory is fallable, but if I recall, the RI-100 sounded on the dark side of neutral, whilst the RS-100/RL-101 combo sounded a bit less so. The separates had a bit more resolution; a bit more life and sounded a bit more open. The separates also subjectively had a bit more control, though that was likely due to the separate power supplies. Whilst the separates did not sound quite as dark, the overall sound signature was the same.

I did see your earlier thread, but warn I am no expert on the features or functionality of the amps you're considering. I still haven't familiarised myself with the setup options of my own equipment!
I owned the Classe CA2200 for a few years and compared it to the CA2300. I also demo'd the virus RS100 and RI 100. The vitus is much better, richer sound, better hold and depth to bass, more detail, deeper soundstage. The vitus is really a very nice amp. Very different cost, I think the vitus is twice the cost or near that of the classe. I would love to have the vitus. 

Hi the_crow.

If looking at the Sonus Faber Stradivari, as Stereophile tests show (below), your going to need an amp that can deliver good current, a good designed solid state amp that has bi-polar output stage (not mosfet or tube) is the typical way to go, one that can almost double it’s wattage for each halving of impedance.

How many watts into 8ohms is not the problem (as they are 93db efficient) so a 50watter into 8ohms will do, but one that can keep almost doubling that 50w  down to 2ohms would be nice. 

Stereophile Test on them states.

"its impedance (fig.1) dropping to 3 ohms and below for much of the upper bass and midrange. And the combination of 4.4 ohms impedance magnitude and –48 capacitive phase angle at 55Hz will give lesser amplifiers conniptions ( a fit of rage or hysterics)"

Out of the two amps you mention, look at the specs and see which one goes closer to doubling it’s wattage for each halving of impedance, hopefully from 8ohms to 4ohms to 2ohms. EG: 100w to 200w to 400w
