Monoblocks or upgrade to larger amp?


I have a Plinius SA 100 Mk.III amp with a Audio Research REF 1 pre-amp, Meridian 508.28 CDP, Dynaudio Contour 3.3 speakers using NBS Monitor I ic's and Monitor III speaker cables. I love the sound on this system. However, I'm considering upgrading the amp to either the Plinius SA 250 Mk IV, or get another SA 100 MK.III and use both amps as monoblocks. What do you all think would be the better way (sonically) to go? And why? From what I understand using monoblocks provides a "cleaner" stereo separation and better soundstage. However, will upgrading to a more powerful amp provide greater detail?

So, pls help: final verdict? Two S100 or one 250 (or wait for Mk4?)? A friend's been plaguing me for the answer -- and I don't know the machines AT ALL! He's got Avanti IIIs to drive.

Thanks!

Viridian: so, does your experience tally with Redkiwi in that the 250 is the better sounding amp?

Excuse my confusion, but your first post just has the one sentence Red reproduced (maybe the rest didn't get posted?) and in the second I can't see your suggestion.
