Wow.... My system is so much like yours I can't believe it. Proac D30r / Simaudio 870a / Classe preamp / Aurender / and all Nordost cables. I see that you run your speaker cable to the ribbon tweeter and jump the mid/bass driver. I tried that setup but it sounded too thin. Were you getting too much bass from the left speaker being close the the corner? I also upgraded the stock spikes to Nordost Sort Fut which made a big improvement. I am now working on taming a few bass peaks with EQ and room treatments..... You have a beautiful set-up and I bet it sounds great!
