Just a little confused. Are you building a 2 channel only system or multi channel because you mention using an AVR as a pre-amp. I would recommend against using the AVR as the 2 channel pre-amp sections in most AVR's are simply an after thought and not of the best quality.
If quality 2 channel reproduction is what you are after, then I would lean toward a nice intergrated to drive those Dyns (nice speakers by the way). The ones you mentioned will work. With a $1500 budget, I would also add the NAD 375BEE and Creek Evolution 2 to your list.
Finally if your asking about an AVR as a pre-amp because you already have one and want to add a Emotiva power amp for the Dyns, I have another suggestion to consider. Get the Emotiva power amp for your L/R mains but consider a 2 channel pre-amp with home theater bypass function. I use a Parasound 2100 pre-amp with this feature in my combination HT system and 2 Channel rig and it works great. I believe Emotiva has a pre-amp with this feature too. Also, many integrateds have it so you can use the integrated (pre and power)for your 2 channel listening but only the integrateds power amp section for HT listening allowing your AVR to do all the precessing and control. I think the Marantz PM 8004, Musical Fidelity M3i and Creek Evolution 2 all have it.
Hope this helps. Good luck!
