Best amp pairing with Aerial Acoustics Speakers?

I would like to assume that any amp I choose will be a keep it forever thing.  The Levinson's should be built to last as well. And ATI, well, they are quality products and a great company.  So, from a  quality perspective, I don't think I can go wrong... It the possible variances in sound that grabs my interest the most.

Do you think that the Class A/B Plinius SB-301 MkII would be just as good as the SA-100 MkIII?  Or should I look more at the Levinson 532H, Simaudio, or something else?

Whats a "good price"  for a used Dread II?  Would you rate that over Levinson or Simaudio?

Does anyone think that the new ATI Digital Class D amps would be good with the Aerial 7b's?

Ok. I have heard the same thing about the Aerial speakers craving current!  That's why I am curious about what is a great pairing of the amps to the speakers. 

As far as the Biamp idea is concerned, what does that do to the impedance of the speaker? Does is make sense to use two separate channels on the same amplifier to biamp? Or is that a waste? 

I have been looking at the ATI class D amps lately because I am a little gunshy when it comes to digital amps. I had a Wyred4Sound amp about 10 years ago paired with my PSB Synchrony Ones and I didn't like it at all. I figure things have changed and the ATI is totally different, but I am still nervous about the tech.  That being said, Theta uses similar N-Core tech in their new amps and people seem to LOVE them with the newer Aerial Acoustic 7Ts, but I haven't heard anything about them being used with the 7b or CC3b speakers...

So that is my conundrum. 

@sfall:

yes, the previous suggestion for multiple amps was confusing so I don't think I would go that route anyway...

has anyone ever heard the Aerials with the older Krell Theater Amp Standard (TAS) amp?  I've seen a few for sale lately and they are REALLY peaking my interest.  Any thoughts, experiences, or advice on pairing the TAS and Aerial 7b's and CC3b?

So, I know that the Aerials like a lot of current, so what about one of the older Parasound amps?  ex: 2205AT or the HCA-2003A?  Those are supposed to be high current amps, but what will I lose by going with those over the Krell TAS?

The same results as with the Bryston or as without an external amp? 

That can't be correct.  The Parasound is supposed to be a pretty good amp

Does anyone else have any input on this?

Thats very good input  Thank you.

What amp do you suggest with the 7b?

Has anyone tried Aerial with the new Class D Amps?  ATI? Bel Canto?  I wonder if they would work as well as a good high current class A/B amp from Theta, Bryston, Krell, etc...

Second question: would the newer Aerial 7Ts require different Amp/processor combos than the older 7b speakers?  I know they have different sonic characters so I wonder about "processor/amp pairing" with the different Aerials...

just a thought...
