Here's my sytem. My goals are to achieve the highest sound quality while keeping cost reasonable and have as much or more clean output capability as I can ever use, so a bit more was spent to achieve those goals vs the cheapest possible option.
L/R----------Revel F36
$1425. MSRP $2,000
Center------Revel C25
$500 MSRP $750
Surrounds--Revel W263 in walls
$250 MSRP $350
Subs--------DIY BMS18N862 4ft^3 sealed subs x 2
$750 used/pair; MSRP $1500/pair. Most of you probably haven't heard of these, but arguably one of the best 18's made:

Sub amp----Behringer NX6000D (1,000-1200watts x 2)
$450 MSRP $600
Sub cabs: PartsExpress/DIYSG flat packs, about $200/pc;
$400
AVR----------Denon X3300
$600 MSRP $1,000
Apple TV 4k-
$185 I think....ish.
Cables: AVR to sub amp Monoprice RCA-->XLR....these work great and eliminated all noise/hum I was getting with RCA to 1/4 adapters.
Speaker: 12 gauge OFC with whatever banana terminals..nice twin screw binding to speaker cables..Sewell maybe?
Sub amp to subs: Speakon with 12g OFC.
HDMI cables are Monoprice I think. Probably
$100 or so in all cables for the entire system.
Umik-1 mic
$100
Harmony Companion Remote:
$100 MSRP $149. I love, love LOVE this remote. Does not require line of sight and always works 100% of the time. Much much much better than the Harmony 650 I had previously. Flaws....keys are not backlit but keypad is very intuitive and usable in the dark once you learn it. I highly recommend it.
So
grand total for audio is about $4860, or lets just say
$5,000 to include miscellaneous stuff I'm not thinking of.
Display, which is really part of the system since its on even for music through whatever Im streaming:
Samsung 75" Q80R
$2500
Grand Total Audio and Video: $7500
Tentative plans for the future:
1) I'd like to sell the subs to downgrade to a slightly smaller package. Current plan is a pair of PSA S3012 subs. They use B&C pro audio 15's in a dual opposed configuration and should match my current BMS in performance, or at least be *very* similar. This will actually cost quite a lot of money without any real performance benefit. The BMS are incredible. I think they are the best overall 18's made, period, cost no object. But my only system is in my living room, and a 4" narrower cab would be nice.
2) I might consider an external amp for the LCR for when I really want to let it rip. Soley for the extra power. I'm not expecting any sound quality improvement other than at very loud volumes where my Denon AVR might be hitting its limits. The two amps I have narrowed things down to would be the Monoprice Monolith 3 channel amp or the Nord 3 channel Hypex NC500. 99.9% of my listening is below -10MV so this would be a very marginal, negligible upgrade, for a rather large cost.
Other than that, I have my current end game system. Nothing else, I want, no improvements that I feel need to be made for the foreseeable future. Only thing I have left to do are to spend some more time measuring, making sure the subs and speakers are aligned optimally, and maybe experiment with higher crossovers. I'm currently at 80 Hz but my subs will play with exceptionally high fidelity as high as my AVR is capable of letting them play. I know localization will become an issue at some point, but I will probably experiment between 80 and 120 Hz.
I'd like to replace my current ottoman which is large and vinyl(fake leather), so horrible for acoustics. I might also consider an area rug to put in the room in front of the speakers to help with acoustics as well. So piddly things.
Oh, almost forgot, I'll probably be changing out all the blinds on my first floor to some type of room darkening blinds/shades for movie watching when its light out. That'll be nice.
