Monitors that use the Dynaudio Esotar Tweeter

The smaller Egglestons

They are AWESOME!! Both Eggestonworks & Esotar!

I believe these are the Western Electric 300Bs of Tweeters! I doesn't get much better, testimony to Extrema and the fact a new pair of same tweeters sold for 1400. on A'gon recently-

You have to remember that any speaker brand other than Dynaudio that uses the Esotar tweeter uses the older T330D, only Dynaudio C-1's and Special 25's use the much more refined version called the Esotar 2.

I have heard the C-1s, and overall don't recall any significant improvement. Sometimes the older IS the better, which is why I referenced W.E. tubes.

Mfgs are always going to "upgrade" their products for sales purposes, right? If the Extrema is a collector's item as other speakers, tubes, etc. could it that the originals have the most value or quality? I'm not in the business, just a hobbyist...
