Does anyone have any experience with JM Labs Alto?

I've auditioned a pair and personally prefer the older mezzo utopias. To be fair the alto's tweeters were not broken in when I auditioned them. I also know a couple of philes that have the alto's. Everyone of them agrees that the alto's tweeters take a very long time to break in.

There must be something about the BE tweeter breakin. I've heard from another, the same thing about the new Micros. When I heard them at Sound by Singer, they were, obviously, well broken in. Don't have a referent, though, never having auditioned the non "BE" line. peace, warren

The best sub for the Micro Utopias is the JM Lab Electra 900 sub. It uses a 13 inch W Cone woofer and 250 watt amp. My friend is using this sub with the Micro Utopias.
It blends in perfectly. He originally had the Utopia sub, but that sub was to big and deep for his room.

The Mezzo Utopia are incredible. I heard them 2 years ago on a Mccormack DNA 2 amp. The Mezzo's sound fast, articulate and the bass is tight and upbeat. It also had one of the best midranges i'v heard.

Thanks to everyone for their response.I just upgraded to the altos.Peace.Jim
