I can tell you that most of the "amazing" black Friday deals are products that don't exist before/after black Friday. These TV's and soundbars are built from leftover parts as cheaply as possible for the holiday rush. You absolutely, positively get what you pay for!
As a former high-performance AV sales guy I'm going to ask a couple questions you need to Honestly consider.
How important are the following? (1-5 scale, 5 being most important)
- Performance (how clear the sound is at lower volumes)
- Price
- Aesthetics (how it looks, how big the soundbar/speakers/receiver are)
- Longevity
These are going to determine what sort of a system you are truly in the market for.
I can't tell you how many times a customer who lives in an apartment would tell me he didn't need too much wattage because he doesn't want to blow out his neighbors. More wattage = clarity at lower volumes, meaning you can keep the volume lower and still hear dialogue. Plus, if the customer cared about his neighbors he wouldn't be trying to buy a subwoofer
Think of wattage as horsepower in a car, would you rather keep your RPM's under 2000 most of the time or constantly red-line it? How long do you think it would last in either scenario. Just my 2cents
