suggestions on speakers for 5.1 setup $2500 range

Look at Paradigm's monitor series. A lot of options and very nice sound for this price (or less). Not essential that the sub be from the same company (for instance, you'll never go wrong with a used Rel), but otherwise I agree with eldarado - buy the same brand for all the other speakers.

I second the Paradigms: lots of great speaker for not much money. Keep them all the same for SACD reproduction or, at least, if you use a speaker made for uses as a centre, get a big one from the same manufacturer.

Or check out the Gallo set up, probably fits the price range....

Ok,

Beat me up again guys ... Paradigm Reference 20 v2's and a matched Paradigm CC center with a Seismic 10

I just saw posted today - 20 v2's and matching center for $1300 find a used Seismic ($900) you might even have a few bucks for stands/cables. I agree the sub can be switched out - the Seismic has a high price but will scare you. Lots of people seem to hate Paradigm for some reason.

PS - I have heard that speaker powered by a little tubed integrated and it changed my audio life. Don’t under estimate the potential of those little guys. I have also heard the Reference line in action at a friends house and thought it both musical and has stunning HT performance. Go and listen for yourself.

Give Quad L series a listen, you may even want to go for 21L floorstander for fronts.
