Hey gus, I understand your good intentions, but right now the 805's price difference with the 705 is almost negligible, I believe... $699.76 with free shipping from Amazon. That's only $65 more for an increase of current capabilities of 36 amps for the 705 to 60 amps for the 805. Also has Burr Brown DACS (I think 705 is Cirrus Logic?), Ultra2 vs Select2, and a 3rd zone. I think the amp section improvement is worth the $65 alone.
