I'm happy without a Fibonacci shaped room, with perfect acoustics. And, no bass boom. ✌🏻👍🏻Many people are a bit snooty and dismissive when it comes to all in ones, particularly the smaller 'lifestyle' models. I think this Denon CEOL N12DAB looks amazing and if it sounded terrible, they wouldn't sell any.
I'd go for something like this, if my system ever failed. I know I won't buy separates again. All those expensive interconnects I've bought will end up in the bin. Spent a fortune.
I think people expect miracles when they buy an expensive system, only to find it sounds odd, due to the room acoustics etc.
Many expensive components, especially speakers, can't reach their full potential due to limitations, which can't be improved, unless Dirac correction is used for example. Expensive. messy, fiddly and unfulfilling.
If we all had a Fibonacci shaped room, with perfect acoustics and no bass boom, then you could easily buy a system knowing it would sound great.
People are buying all this stuff and they're never happy, so perhaps it's their surroundings and furnishings causing the dissatisfaction.
