Yeah, I can't argue with anyone if they think vinyl is the best format. I can respect that because I myself love vinyl as well, even though I'm not a collector. But cassettes??? Heck no. Even for Black Metal, somehow I always want to hear that crisp double bass kick in, you know?
Heck, even with vinyl I noticed the low end is just, well...non-existant. And I have a top-notch sound system. So, for full-out sound quality on a high level, CD will always win over for me.
But, to tell you the truth, DVD-audio is where it's at for me now. Wow, those things sound nice if you have the right set-up. After I witnessed what can be done with these things (In Absentia and Deadwing dvd-audios) I was just blown away.
But hey, everyone has their personal taste. It's all good.
