krell KSA 200S or 100S to drive mani 2's?

Krell KSA 200-S or 100S to drive otem Mani 2's anyone know or have first hand experience...I have a pair of totem Mani 2's, they are 4 ohm resistive load w/ peaks well below that on diffivult, demanding passages, and for subterranean bass they are (potentially) capable of...are suggested specs raings are 80 to 200 watts into a 4 ohm load...so a 100 watt into 8 ohm amp like a Krell would successfully double into 200 watts at 4OHM, clearly a 200S would deliver 200 watts into 8 ohm load, or 400 watts continuous into a 4 ohm...more than adequate headroom...from a financial/purchasing as well as getting true performance out of the speaker, is a strong 100 watt into 8 ohm amp that successfully doubles with halving of impedance, is this plenty successful, i.e., Krell KSA 100S or Audio Research 100.2, or could the amp still not do as successful a job and be overtaxed m and therefore is it worth the extra money to purchase a larger 200w into 8 ohm desing, one that would double to 400 watt into a 4 ohm resistive load and provide left over headroom...any thoughts or experience are apprecaited

I have a KSA 300 and the great thing about the KSA is should you get an impedance swing (I sold latter Krell FPB series fro '96-2001) some speakers that have stated specs like our nest seller B&W 803 was 90db @ 8ohm but that could go down below three ohms.In any case KSA series was only amp series that Krell made that could go stable into 1 ohm load continuous (which with mine makes it 2,400 into 1 ohm!) and some say it actually goes stable into .5.So you might be able to get by with 100 watts but like they say you can't have to much.

With Krell you get the (IMHO) good and bad with clean high end and nothing with more grip on bass though I think both A and A/B Krell has slightly metallic or "etched" mids-then again I like tubes a lot.But it's a totally different sound with AR and I am sure you know the difference.Tube pre on top of Krell would be great with Mani's (which are classic great speaker).Haven't heard the AR but it has a great rep as one of their best amps. like.Other high current stuff would be value wise Bryston ST series 4 and up.You don't need a pair or Parasound JC1 400 wpc mono's for them (I love that amp-also like the Plnius a friend wants one for his Forrest's).Long story short Krell will give you the grunt you need at 200 wpc but 100 if not in to big a room or too loud would do it.
