i have rf-7 front & rf-5 rear, & a pair of synergy mini towers in my office (i think sf-1). after nearly a year of demos, i dropped my 2805 for an anthem avm 30 & krell kav 2250 amp for the fronts, still looking for a reasonably priced kav 3250 for center & rears. denon & klipsch are not a good mix in my opinion. i have the 3805 sound fantastic with a set of vienna accoustic bach grand speakers, and i have heard my speakers with the denon receiver & without, & much better without. this is not to knock either denon or klipsch, i personally don't like the sound they produce together. unfortunately i don't have a cost effective solution for you.
