IMHO the SFL-2 is the better match for your system (Flavor aside). As Thorman points out...it is the most neutral which I would want in my system if I had the Krell/Dunlavy combo. It also has the balanced outs for your Krell and will be quieter along with better bass.
$1,000 may be somewhat optimistic for the SFL-2?
