They are still packed away in their boxes awaiting the new house build (early April), along with my new 65inch 4k tv for the living room, Integra 5.3 amp and (on its way today hopefully) Sony 270es 4k projector. I'm not known for my patience at unwrapping new toys, so its killing me not having anything set up and listening to TV/Movies via a Panasonic mini system over bluetooth. Also waiting on Integra / Onkyo to release their 2019 2ch receiver (TX8390 or DTM-7) to drive the R7s.
