Brendan, I'm in the market for a new surround sound soundbar system for my 70" TV. Looking at the Sonos Playbar system, the Nackamichi Shockwave 9.2 and the Samsung HW-Q90R.
Any thoughts?
I've been a Sonos fan for about 10 years and recommend it to everyone, for a few reasons: Simplicity, Product Longevity and Sound Quality.
Regarding simplicity: The system works perfectly, everytime. While I'm a tech geek and can figure out how to use just about anything with buttons and knobs, my wife and kids are total opposites. With Sonos, you turn on the TV with your regular remote and the system comes on with it. Listen to music from Spotify and you can cast it to the system without touching it. Ask Alexa to play a song and she'll send it to the Sonos system automatically. There's no special power-on sequence, no inputs to select, no settings that can be easily messed up. My whole family can use Sonos, and I never get a call during a gig to tell me that they can't get the sound to play. I have a Playbar with 2 Play 1 speakers in my living room (the equivalent to a 5.0 channel traditional system), and a Playbar with Sonos Sub and two Play 1's in my basement (the equivalent of a 5.1 traditional system), plus an assortment of other Sonos speakers throughout my house. I can play the same source on all of them, or different sources on each of them, from dozens of options... TV sound, Spotify, Pandora, Sirius-XM, iHeart, TuneIn, Radio.com, Slacker/LiveXLive, whatever's on my phone, and my networked hard drive containing all of my DJ tracks.
Regarding Longevity: with the exception of their standalone remote controls (which were discontinued years ago and replaced with app controllers for iOS/Android), the oldest Sonos products still work perfectly in conjunction with their newest products. I've built my whole Sonos system mostly by buying it used on Craigslist or Facebook marketplace, never once having to ask myself "will this be compatible with what I have already"?. Every product within the Sonos ecosystem is linkable to another, regardless of when it was introduced to the market. If you ever need to replace this system, it'll be because your house burned down or a zombie apocalypse happened.
Sound Quality: Better than average (as it should be, considering its price). Technically, it's a trade-off, because Sonos downconverts 7.1 and 9.1 audio to 5.1 and doesn't support Dolby Atmos (yet). It might at some point, but it's not a priority for the company. Their focus is on perfectly-working wireless audio systems, and there's only so many audio channels you can send wirelessly while maintaining perfect synchronization with what's on the TV. Still, the sound quality is impressive...I've yet to watch any movie where I wasn't blown away by the audio quality, and I never think to myself "hey, another two surround channels would really make this system kick ass". I'm a DJ and musician... having great sound matters to me, no matter the situation. If I had seven ears on my head, maybe I'd reconsider the advancements of 7.1 and 9.1 or 9.2 systems, but I've only got two. Sonos' sound quality is excellent by my standards.
You won't regret a Sonos purchase. If for some reason you do, it holds its value better than a Lexus. You can sell it for not much less than you paid for it.
As for Nakamichi... they're not the same company they were in the 80s and 90s (to be fair, few of those companies still exist like they did during the Japanese hi-fi boom in the early 80s). A few years ago they were selling cheap bluetooth speakers at Kmart. I can't vouch for the quality of the Shockwave 9.2 system but I noticed that the surround speakers that it has are not wireless (they use RCA cables that connect to the subs) and the system comes with a remote control (with a button for seemingly every little adjustment you could make to the system). Also, from what I'm reading, the satellite speakers are either surrounds OR Atmos up-firing speakers, depending on how you place them... vertical or horizontal. They don't handle both without reconfiguring their placement.
This review of the Shockwave system is interesting... 5-stars, but everything the reviewer details makes me think he's just trying to justify the cost of the system to himself.
