I almost went with the 650s over the 800s because of the price point (of course) and all of the reviews with people saying that they preferred them over the 800s for just your standard listening of pretty much every genre except maybe classical because the 800s were too bright to them to the point of being unlistenable as well as too “clinical” sounding. Personally I've never had a brightness issue, luckily, although I can understand what they mean about them sounding clinical. Some albums, while still sounding good, just don't feel like they have much life to them, but to me it's just an accurate representation of what those albums truly sound like for better or worse and I like that, and once you find the right one it's like magic. They really show off the difference between something mixed and mastered well compared to something that's not, which just stands to reason when you listen to an album that's done properly and with care in both regards the music nearly comes to life. It's fun as hell to go back and listen to songs you've heard hundreds of times and it's like hearing them for the first time ever and you notice things you never heard before. I love seeking out which pressing of an album is the “best” and then getting it. I just have a blast all around with music now.
