Step-up from Plinius SA-102?


I use Plinius SA-102, it's a great amp, but i want more attack and control. I've also tried the SA-250, but it wasn't what i was looking for!
I've been recommended to look into Krell. I've heard the fpb 250 mono's at demo shows and found them somewhat fatiguing quite fast!
I also got the impression they are not suitable to speakers which easily can be provoked, to sound a little harsh with bright sounding equipment?
Speakers used are an advanced small serie speaker, it was never put in real production. Mostly for the reason, they were to expensive to build. They are very much alike Avalon's Eidelon and likes in Kharma range.
A 2-way monitor, with ceramique's from thiel and partner.
Each bass-module employs a 10inch tc sounds
(wisdom audio use these) bassdriver cutting in at 100Hz.
They truely has a sensivity as low as 83db.
Impedance is nominally 4ohm but never below 3ohm.
They respond directly to what you put in the chain!
Other links in the chain is,
Meridian 588 and Classe 47.5mk2.
I have decided to first concentrate at amp!
So, anyone with suggestions?
I'm most thankful to anyone sharing info and thoughts!
Ok, thanks for looking in!

The Pass is a good suggestion.Also consider the Edge NL series,Plinius SB300 or Halcros.Lamm M2.1/2,2s?
I think Duke nailed it, as usual. I have owned Krell before. My favorite was the older KSA 250. I had it for 7 years. The newer ones sound a little sharper to me. Lately I have been listening to the Parasound JC-1's and am very impressed with them. No listening fatigue. These would be over 1000 watt monoblocks on your 83db speakers. I think it would be a great match, try to give them a listen.
Consider a pair of bridged BEL 1001's.
These amps are tough to acquire but have a cult following.
I've heard the Plinius 102's transform to another level when bridged. Why not try this approach first?
The SA102 tends to lack bite, and it sounds like that might be why you are hankering for a change. I was in a similar position a few months ago except I was reducing the sheer size of my second system (keeping my lovely wife happy) and replaced the SA102 with a Perreaux Radiance integrated. The music definitely became more engaging, but it did lose some of that muscularity and emphasis on inner textures that the Plinius had. My point is that I doubt that you could say the Radiance was 'better', but I ended up with a more musically engaging system and I am pleased I made the change. If I am right that the music has become a little bland for you, then the issue is probably less about what is better than the Plinius, but simply that the Plinius sound is not what gets your system boogying. There will be many amps that you could look at that will overcome the problem you are having with the Plinius.
