cassettes CAN sound better than vinyl.

I thought tape width, depth, and speed were all involved. 

Yes! it's all true. 

mp3s are better than cassette tapes.
there, i said it.

my husband prefers  something called 128 as the quality.

Well, you might believe it is true and are certain entitled to your opinion, however why are inserting MP3's in this thread about analog. (notice the category)

Cassettes, for me, were ever more than a way to get my curated music on the road. Now that I can get more tunes on a drive the size of a thumbnail (with easy access) than a station wagon packed with cassettes who needs 'em?
Better sounding too.
