Lazy Susans setup is ready - gave it a spin and turned out well!

With one hand I can rotate it and switch between R3 and DBR62 in the exact same position besides my monitor. Switching a Dirac profile takes about 5 seconds and in that time I can switch the speaker with the switch and turn both speakers. Pretty neat! For anyone considering to do that get a stable lazy susan or mod yourself one with more stable platform turning hardware otherwise you risk your speakers going on the floor.
Found another cool benefit of the rotating platform - tied a couple of strings on each side for the IsoAcoustic stand legs and using them I can rotate it from a distance, changing the toe-in angle of the speakers. Using that I was able to experiment and find the ideal angle where the balance was between a wide soundstage (when rotated outwards) and depth/coherence of the soundstage (when rotated closer to listening axis).
Tried stuffing the ports of R3 and here's how the Dirac calibration looks like with ports stuffed completely:

The big bump from 30-50Hz in the previous measurement is gone now, apparently it was all from the port plus boundary reinforcement from the wall 10 inches behind the speaker. I like how my Dirac calibration is only from 60Hz upwards and the port affecting mostly under that it means I can use it ported or stuffed without recalibrating based on preference. Listening to it ported I'm really doubting if my subs will add much. Integrating subs will be next though and I will use R3 stuffed as the sub will do the 30-50Hz range and the port won't be needed.
Now that I have a "good enough" speaker, I was tempted and got into another comparison that I've always wanted to do - between amplifiers. I've hooked March Audio P452 and Buckeye NC502MP on the switch playing on R3. Let's say the results are surprising to me
More amplifiers will be joining the comparison - AIYIMA A07 and an Onkyo TX-NR737 AVR with 125W class A amps. Will post a separate thread for that.
