Probably one issue could also be that a lot of this stuff is actually pretty well made, and repairable. My old NAD amplifier is more than 25 year old and doing great. I don't need a new one. I've switched speakers a few times, to better fit the rooms as we've moved, but the amplifier just sits in a corner with the CD player and turntable.

I'd agree with others, speakers aren't that concerning. There are niche speaker manufacturers and used or refurbished is still a good option. To be honest, I'd also look to the used market if I where to replace my amp.

Personally I don't have anything against Samsung, but I doubt they'll be a good steward of those brands. Corporate interest and niche high quality audio seems to at opposite ends of the spectrum. I could be wrong, Sony makes nice stuff, maybe Samsung will as well.
