I don't think the 391's are better than the busmans at all. I would love to hear a comp, but the 39x series does not impress me in the low end either...
They're fine for me and that's what I listen for is clarity of bass.
I didn't get that from the busmans. Which is why I dig the AKG's a ton more.
Different strokes for different folks I guess.......
Take a listen to the shows on the archive. Not much bass there.
Very thin and airy. Great highs though.
Not really that big of a deal. Just not my bag or else I would've gotten the busmans.
I am more than convinced that I will get better low-end from the 391's.
I compared from torrents and what was on the archive and taped with my 391's.
I dig mine a lot more or else I would switch.
