So, you have a nice size space, and will get new speakers and new amp, correct?
My 50 years of accumulated preferences: Efficient full range floor standing speakers, large front facing woofers, no ports; and Tubes for both preamp and amp. I also like tubes for MM Phono RIAA, and a SUT for LOMC to keep using those tubes.

My vintage speakers have horn tweeters, horn mid, and 15" woofers, with L-Pads to adjust the drivers in the listening space which I consider vital. I drove them for many years with 30 wpc tube mono blocks, now a newer Cayin Integrated A88T which is either 22wpc triode or 45wpc ultralinear, either enough power: I prefer KT88s ultralinear.
My full featured vintage tube preamp includes two MM Phono inputs, and I use a SUT to boost weak signal MC.
