This is impossible to answer without more information. The D-Premiers look like excellent value and they give very little away to a current D-800, but of course you can't use SAM (and some other later features) with a D-Prem.
Do your current speakers have a SAM profile? Is it likely that you'll buy new speakers in the medium term that would benefit from SAM?
And to pick up on Phil's point above, some of those prices look utterly bonkers! Is this a trade deal, VAT free or something? Or maybe you have intimate pictures of your hifi dealer that he would prefer were not made public?
