Would love opinions on my HT puzzle

I'm a new member and I want to say that I love this forum! All you folks out there seem very passonate about this community! Glad to be a member now...

OK, I have recently started to build my HT system... The first component was the addition of the Krell HTSII. I also just picked up a used Aerial CC3 for my center speaker. I am currently running an Aragon 4004 with Thiel CS3.5 speakers. They are the only components that I'm even considering keeping while I build the HT system. My goal is to buy as many "great" components online as I reasonably can, obviously for the cost saving benefits... I also would like to build over time, so I want to my smart acquisitions that give me the most flexibility too!

Here's my plan so far

Amplification:
Krell KAV 200a/5 and get rid of the Aragon or
Krell KAV 3250a/3 and use the Aragon for front or rear depending on speaker selection

Speakers: (If I go this way, considering using the Thiels for rear) Budget is < $5,000 new or used
Aerial 10t or
B&W Nautilus 803 or
Dynaudio Contour 3.3 or
Dynaudio Confidence 3 or
Aerial SR3 for rear and keep the Thiels for the front for now

Subwoofer: Budget is < $2,000 new or used
Revel B15 or
REL Storm III

DVD:
Pioneer Elite DV-37

I think that the speaker decission will drive the direction on amp options. I'd love some input from this forum! Thanks.
