You may be satisfied with the audio quality in an arena, but I would find it unacceptable at home. To each his own...
Since you reference the design of arena systems you must have the details at hand. Please provide at least line drawings of a $1M plus arena installation that includes details of the speaker wire runs, speaker impedances, etc. Please also provide the requirements that were used to develop the design. This will allow comparison between a home audio system and an arena system.
In the audio realm Samsung seems to be most noted for the audio from their TV's, sound bars and perhaps 5.1 in a box systems. Again, that's not what I'm shooting for in audio quality. Samsung's existing products make it a bit scary to contemplate what they will do with Harman; auto, JBL, Revel, Crown, ML, the whole group. Seems that I read that Samsung has built a couple anechoic chambers in L.A. and hired a few Harman people, so there is hope.
The laws of electricity have not changed since 1988, neither has human hearing. Speaker design for the most part has not changed since 1988. Sure, some of the stuff has improved and aside from plasma tweeters...there is nothing actually new in consumer audio. Cones, domes, concentric drivers, ribbons and AMTs have been available since the 1970's and before. The horn profiles have changed and in pro audio, line arrays, horns, synergy horns and tapped horns have shown up but the guage of wiring has remained the same.
Some materials from neo magnets and different composites have updated some of the drivers but that has nothing to do with what cables you need. McIntosh did a study in the late 70's/early 80's and it does not matter as long as you get the correct guage of wire. It does not matter, it has never mattered and until the human hearing drastically improves--it won't matter.
What I like about pro audio is the "put up or shut up" way it operates. We are not talking about some person playing a tune at low volume in a room that is temp controlled and never moves. This stuff moves constantly with massive power amps, power distribution, testing, calibration and setup--then rip it down and haul it a thousand miles and start again sort of thing. I watched a video detailing the design of the Meyer system used by Metallica some years back, very distinct with 64 massive subwoofers flying 30 feet directly over the drummers head.
They did it that way to improve the sound quality and dispersion over the arena and it was done on paper (actually a napkin) and it was ready 15 minutes before the first show. The system cost 8 figures--the band believed the guy could get it right and payed for it... and it worked.
The 10 to 20 million dollar PA system first fired up the day of the show, they did a calibration on it then played it's first song. Infected Mushroom (EDM) roared through the thing and the band ran around the arena listening and measuring for dead spot. No dead spots and they were getting 136 to 140dB for sub bass
They used Infected Mushroom because it uses square waves for bass frequencies and is completely full range so they could strain the system beyond actual concert use. After that, they took their positions and the first people stormed into the arena and Metallica was on tour the next few years. How much does it cost to haul well over 10 tons of gear around the world for two years? Set up, tear down and transport costs are staggering so a wild guess of at least 50 million. The sound quality was incredible and beat out the U2 360 tour easily--the calculations started on a napkin.
So poo-poo and dismiss pro sound/arena sound and THX/IMAX systems if you like. The Metallica TM system was an idea pondered by one guy in the 1980's. After all "real" audio is for the home with such drastic and constant improvements something as simple and known as the laws of electricity change yearly--need to do more, more and yet again MORE testing! None of that put the wire on a scope, run signals through it and read the distortion either... no plug in measured impedance curves, plug in the guage of the wire along with the length and get a result. Using science and math to calculate something is old school, we need blind ABX testing to prove yet again things that are designed with science and math.
As far as Samsung being unable to make decent sound equipment, ponder what you are saying. Think about the technology required to build sound equipment then think about what Samsung does and manufactures. Samsung manufactures their own parts be they processors, memory chips, boards, displays and so on. They don't have to wait around for a new DAC, transistor, processor or anything--they can build what they want, when they want and not let the world know until they release it. They are used to a 6 month to 1 year window with tech, the glacial speed of the audio industry will be easy. Not only does Samsung make electronics parts, they also build skyscrapers (Birj Kalifa in Dubai) manufacture tanks for the S. Korean Army, make massive LPG tanker ships, commercial trucks and navigation systems. 12% of South Korea's GNP is Samsung--I'm sure audio won't confuse them too much.
But back to a piece of wire--since human hearing has not changed recently, wire can be measured and a speaker's impedance can be measured, the results can be calculated. No reason to blind ABX test every speaker that comes down the pipe because it is "new". The test results from the past 4 decades of testing are still valid so run the calculations and be done with it.
I did blind ABX testing on wires, CD players and amps 26 years ago (not double blind) Could not tell the difference so my ears matched the math. These days, my hearing has not improved so I won't waste my time retesting etc... the days of hearing the high pitched ringing in CRT flyback transformers are gone
So relax, throw some 12 guage on your speakers if it makes you feel better then use the money to purchase more music, movies, acoustic panels--heck, send it to Scott so he can purchase some more testing gear for the site! (shameless plug) Poor Scott spends all his money keeping AVS going, he can't afford a razor. Hook him up! If it is all about the sound quality, focus on that and win.
