Krell iBias or Mark Levinson 533/535H series amplifiers with Aerial Acoustics Speakers?

My cousin has a set of Aerial 10T's.  They are very fast responding in the mids and highs.  The JC1 would probably be a good match in my opinion.  The Krell Chorus or Dual/Solo amps would be another good choice as the high frequencies on the Krell are very smooth and clean.

I would avoid fast high resolution amps like the Bryston Class AB amps.

The older generation Aerials (such as 7B and 10T) used a very responsive aluminum dome tweeter.

The new generation 7B uses a ring radiator and has different mids.  It is a completely different speaker and much more laid back and smooth.

So, an amp that would match well with the old 7B may be too slow/warm on the new 7T.

The Krell Chorus/Duo/Solo amps are excellent amps. Very smooth, very refined with lots of resolution. However, they are not extreme high frequency "air" amps. They would be an excellent match to the older 7B. They would definitely sound good with the new 7T, but you’ll find that you’ll lose high frequency extension with that combination. If that’s not a concern, then the latest Krell amps are great choices.

I always caution people on Mark Levinson, because it’s a case of "you either love it or you hate it". I found that Levinson has a very interesting midrange and the soundstage is kind of weird - I find it too compressed or closed in (in a sense). But for many people, they just love the sound. So, I would suggest you go listen to an actual Levinson amp first before deciding.

What is your current preamp / sources? Inteconnects / speaker wire? All these can influence what kind of amp you should choose.
