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?

Viridian, you wrote "The difference in power is very negligable, any of you slide rule types out there want to calculate the power difference in db for us?" Somehow I cannot find the point you claim to have made about sound quality being the deciding factor - do I have to try reading it backwards, or have familiarity with the Koran? Or is your point on some other post somewhere and I missed it?

You also wrote "Maybe Redkiwi should actually try to read the posts before responding." Maybe Viridian should actually try to post the point he is claiming to make before claiming others are not reading it.
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.

Sorry for me adding more confusion than what already seems to be piling up on this thread. While i have heard the SA-100, i was basing my comments on one SA-100 vs one SA-250 in terms of db comparisons. Sorry for not being too clear on that one.

As to Redkiwi's comments, i too would go with whatever amps sounds best. If the sonics are there but the power isn't, you could always double up on the amps. While this could be quite costly, did you think that you would get away "cheaply" in a hobby like this : ) Sean
