Replace my Usher be718 ?

Audiofeil are u referring to the many many Taiwan direct import specimens floating around or the ones with the better crossover aka the non-gray market imports?
I have listened to both and they sound completely different from each other.
I bet the ushers are power hogs simply because the cheapie inductors used for the woofers are quite lossy.

I've found a pair of Harbeth 7es-3... most likely will make an offer... thanks for the response....

can a pair of usher diamond tweeters be purchased and dropped in as a replacement?

What kind of music do you listen to and what are your electronics like?

Mboldada 1, 'Can a pair of usher diamond...?' Yes . But as
the earlier tweeters are not beryllium the 'diamond' are
not diamond. To exchange them make no sense at all. The
so called 'beryllium' tweeters are excelent so no need to
mess with tweeters. In my BE 20 I prefer 'beryllium' above
'diamond'. I assume that the BE-20's are individualy 'tuned' with cross-over components. Ie the produced tweeters have some variations(+/-3dB) so they need to be adjusted to the intended specifications. This can only be done with cross-over corrections. To exchange
one tweeter for some other is not as simple as some think.
