Amp for the two channel.....ML vs Proceed

I'm working on upgrading my BR system.

Two channel only (current system, Pioneer Elite VSX-09TX, JSE 1.0 Speaks,Sony DVD as tansport (nothing worth listing), I'm considering a few options as the AV receiver I've been using will be going to my girlfriend once she closes on her house. I've also got a Linn Ikemi that's available for use in this system....

1) Proceed PRE/HPA2
2) Mark Levinson # 383 integrated

I'm using an older pair of JSE 1.0's there, they'll easily handle 300 watts/channel, so both are acceptable.

The true issue is that I'd like to end up with a pair of Eggleston Andras with a ML 33(4or5).

I'm looking for any insight you all may have. I've got a few plans in mind but....

I'm looking for insight into the pro's/con's of buying a ML integrated (high on my list) vs. seperates (Proceed pre/HPA2)

You can save me the obvious of seperates vs integrated, unless it specifically pertains to the ML 383..
