Super cool system you have there. I always felt a slight loss of resolution. Your system is all tubed and the application I installed the PARC in was all tubed also. It might not be as noticeable in a solid state system. Ultimately, I made room and tuning changes that satisfied me.
Looking at your room, I would recommend some tube traps to experiment with.
