ProAc D28 vs Usher Dancer Mini 2

Mc4b, the new models with DMD tweeters are a little slow getting out in Canada. I was able to get a pair of the Mini Dancer 2 Diamonds for a customer of mine, and even new out of the box I really liked what I heard with the new DMD tweeter. I really liked the old titanium/BE tweeter a lot, but from what I could tell on short listen, I'm liking this one better. My business partner felt the same way too.

In my system, I had been using the Mini Dancer One BE and sold them in anticipation of the new ones, but the MD1's with the DMD tweeter will only be available in Canada in June. Just on brief listen though with the Mini Dancer Two Diamond, I would agree with the statement regarding the DMD tweeter having more detail but in a relaxed manner. I certainly don't think you'd have anything to worry about at all. This tweeter will be very easy to listen to without fatigue, IMHO. I already felt that the old titanium/BE tweeter was fantastic, but when I heard the new DMD tweeter I was pretty excited at what I felt was going to be a definite improvement without any drawbacks.

For what I listened till now, I prefer the ProAc D28.

Mc4b, I think you definitely will need to listen for yourself. In the past, I was choosing between Proac and Martin Logan and ended up with ML. This was several years ago. Usher was the speakers that finally convinced me to switch back to dynamic speakers from electrostatic. However, I have not heard recent Proac speakers so I am not sure what they are like now. DMD definitely has lots of detail but is very very easy on the ear. I love the old BE tweeter but DMD is exceptional, in my opinion.

Nice "looking" speakers but if you do a little research I seriously doubt they're using berylium OR diamond drivers given pricing I've seen

Smells to me more like the HD Radio advertizing which some may think to be High Definition rather than Hybrid Digital...

Same for Usher using BE and DMD monikers?

Usher isn't claiming the domes to be pure diamond domes. Here's some info from their site:

"...laminated diamond-metal-diamond structure, which consists of a proprietary metal alloy base layer coated with an amorphous diamond-like carbon layer (pure diamond is carbon atoms arranged solely in sp3 bonds; amorphous diamond-like carbon has mixed sp3 and sp2 bonds to achieve its desirable properties) on both sides. The base metal layer of the Diamond DMD dome tames all the diamond layers' unfavorable sonic traits and brings out the best of both materials."

There are many excellent tweeters available regardless of material used. The Usher BE tweeter was easily one of the best tweeters I've heard even though it was mostly titanium.
