Your thread appears to be a bit dated (no new entries since mid-January and now it's April), but I wanted to add the obvious, namely, that your best move would be to demo speakers in your home with your equipment if possible. Doing so is the only way to know what sound you are going to get and to know whether a given speaker mates well with your room and your electronics. If you buy speakers that sound great at the dealer, but get them home and find that they excite a room node or don't have synergy for whatever reason with YOUR room and equipment, you're dead (this is a real risk given that most of the speakers you mention can really do bass and you are using Krell monoblocks, which themselves have prodigious bass). A decent dealer should cooperate with you in this regard (although many, if not most, don't want to do this), especially given the sticker on the speakers you are considering -- their mark ups are usually at least 40% on speakers, and more so on expensive speakers, so they should work to earn, for example, the $10,000 they clear on a pair of Watt Puppys.
Good luck.
