High end amp recommendation in China

I need some help.

I am in the process of upgrading my amplification. My current system consists of Egglestonworks Rosa loudspeakers being fed by an Electrocompaniet EMC1-UP CD player through a Mark Levinson 383 integrated. Analysis Plus silver cables all around.

Overall, nice sound - very nice actually, but the 383 doesn't drive my Rosa's with the authority I want.

But here is the wrinkle - I live in Shanghai, China. High end options are limited. I have a very good dealer here who is very knowlegable and helpful, but limited in their selection. My choices are Krell, Mark Levinson, and Halcro (and Graaf if I want to head down the tube path - I don't).

I am demo-ing a 320S pre / 436 power set-up in my home now. First impression - wow - talk about authority! Sucks me WAY MORE into the music than my integrated. Bass, imaging, width, and depth. I have heard the Halcro stereo amp (the 38?)demonstrated in the store - double wow - though I think it is out of my price range. I have yet to listen to the Krell's, but my previous experience with them back in the States is that they are not the sound I am looking for (Lyle Lovett, Eddie From Ohio, Diana Krall, etc)

So give me your opinions / experience.

Yes, yes, yes. I know - I intend to listen to my ears. I am just looking for some help to guide my ears into the right general direction.

No, no, no, don't tell me that these all are horrible and non-musical and that I really need to listen to Brand X - its just not an option for me.

In advance, thanks for your help!
