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

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

The ''upgrade story''. Joachim Gerhard was/ ís the most talented 
speaker designer in Germany. His Virgo was the cheapest
Stereophile A class contender ($5000). His next was Caldera
considered in Germany as ''measure of things''. But in USA 
someone discovered '' cheap wire''  inside the Virgo. So many
upgrades with ''expensive wire'' were started. Those who wanted
to know ''why'' used the oportuity to ask Joachim himselff. The
question to him was put more polite not as ''why deed you used 
those cheap wire'' but as ''why deed you use THOSE wire''?
''Well '' Joachim answered ''we deed try about 20 different wire
and thouth that ''THOSE'' soundend the best.
