Deed any Usher BE-20 owner try the new diamond mid-range driver?

I was not able to find diamond tweeter enywhere. So I will first
try to tame beryllum tweeter with extra resistors. I think that Usher
strategy is to sell the same speakers with new drivers instead to
sell drivers as separates. The difference in price is +$5000.
''Beryllium'' was a kind of ''fake beryllium'' so this may also be the
case with ''diamond'' drivers. Besides there was no consensu among
members in the ''old discussion'' reg. the tweeter about the question
which was better sounding.  

Usher has been transparent about the dmd process to avoid (I think) more bad press. I never heard the previous version but there’s xover upgrades also available for the BE 10-20 speakers. The last couple be20dmd Pairs were listed for under $8k and mine went for exactly what I paid $5700 and for the money good luck finding better.

Im pretty sure the diamonds are fake, lol

The crossover for both; BE-10 and BE-20 is designed  by
Joseph D' Appolito. World authority reg. crossovers. To ''improve''
those huge amount of arorgance is needed. But American and
European versions are ''tuned'' + 3 dB above 35000 Hz. The
assuption was that ''óur tastses'' need  this. H. Pearson refused
to review the BE-20 for this reason. Assuming that my assumptions
are true I am willing to invest in ''some'' ( 2 per side) resistors for
the (beryllium ) tweeter. 
The other approach is like by speakers: changing ''cheap wire'' for
''expensive kinds''. 

I think gp acoustics Offers xover and internal wiring upgrades for around $600. I can look. It up if you like
