I like the M3s with female vocals but men can sound a bit chesty.

If you want to hear something outrageous, grab Loreena McKennett's Elemental and a pair of M3s (sub mandatory-I'd cross it over at 100Hz), a SET tube amp and ... well, I tell you what, that there's audio nirvana boy.

Enjoy the Music. Trust your ears. Laugh at Folks Who Claim to Know it All.
