I'm biased, love my 805's, have a back up pair in a box still off eBay.....
I have run them happily on NAD 7600, 7400, Apt-Holman and Bryston 1B, as well as currently (don't laugh) OPPO 105 XLR to Bryston 3BST.
like the last set up best, so clean. But, with age, I'm sure there has been some HF attenuation. YMMV.
