Can anyone weigh in about the M4U1 upper-mids sounding a bit honky or shouty (when UNAMPED, as this is how i will use them)? The NAD HP50 earpads are acceptably comfortable to me, but in comparison to the Beoplay H6, the NAD's earpads show their flaws and unspectacular seal, so I'm thinking I might replace them with an M4U1. I don't have that sharp of an ear (nor do I want to, lol), but I can tell that the H6 (2nd gen) is a bit honkier with vocals than the NAD, so I'm somewhat worried about the M4U1's energy. The treble is apparently a bit sharper on the M4U1's, so I hope it doesn't sound artificial.... Any other possible inferiorities with the M4U1 (when unamped)? sloppier bass/highs? same mediocre earpad comfort as the NAD (not concerned with headpad)?
simply put, I've seen a lot of posts saying the NADs just edge out the PSBs on sound quality alone....
if you think there is a better alternative when UNAMPED to the NAD HP50 feel free to suggest some (please do not recommend: b&w p7 BASSY, Momentums BASSY, ath-msr7, Beoplay H6 either gen UNEVEN, Meze 99 classic UNREFINED BASS, mdr1a, open headphones, or hard-to-drive headphones). Pretty much the only alternative I've found might be AKG-K553, but I'm also concerned about the questionable seal and possible thin mids on that. hmm. thoughts?
