Got back from the 2 week vacation. I couldn't find an AV dealer in my travels. It was a long haul home. (2.5 hours flying time from George Town in the Bahamas to Charlotte NC. Then 6 more to Seattle; and finally about an hour to Vancouver.) Of course the airlines lost our luggage en route.
The Thursday after we got home, my Misses fell coming down the stairs from our bedroom to the main floor and broke her left ankle in 3 places. She had emergency surgery, and they put hardware (screws, pins, and plates?) into it to reconstruct it. She has to stay off it 100% for 2 weeks minimum, and then gradually add load as the doctors see fit. The timeline is for a 6 week rehab. So it's been all about that, and other "events" since.
So my HT progress has been nil for some time now. The Family Room HT hardware is complete, as I negotiated no more changes there in exchange for new speakers and a receiver (that for my birthday) for the Games Room. The Denon AVR-S900W is working fine now amongst the still half full storage Boxes from the Reno.
Being in Canada (as opposed to the USA), the number of good "brick & mortar" AV Dealers has diminished greatly in the last decade here in Vancouver; as On-Line buying has become dominant. So it's hard to hear anything before you buy. I installed the in ceiling speakers having never even heard Atmos, not even in a Theater. I don't go to movies since I went down the HT road. If I want to see a movie, we wait for the DVD / BluRay => and by then I often forget about it.
Mostly, my HT setups are for Broadcast TV via cable (with it's notorious crappy HT sound) and my BluRay Concerts with lossless codecs (which are fabulous).
That being said, I struggle to plunk down $3K Canadian for a 11 channel receiver, and possibly another $1900 ($1500 USD) for the HSU 3.0 CCB-8 Speaker Package after we blew far past the budget for the Renovation, and the unexpected Bucket List vacation. This is especially so when I haven't even heard Atmos or any of the hardware I'm considering.
By the way, I do have REW and a USB Mike with a PC configured to analyse my HT setups. I have tinkered with it but as yet are not proficient enough for serious tweaking. It's all about time. When you travel for work, putting in long hours, and have a lot going on personally (as above) mucking about with my toys seems to fade into last place.
