Mike, nice finish! You will really enjoy listening and looking at them.
I don't really have any cable recommendations. There was a particular Blue Jeans cable that Trevor and I both tried which didn't sound right to us compared to others. It was very obvious BTW.
This is what I've been using with all my systems. I use 10 AWG with my active LFR1100 woofers, 12 AWG with the mids and 14 AWG with the tweeters. I use 12 AWG with the M5OW and bookshelves, M50, M3, and M2. I used 10 AWG with the M100s before they were stolen.
