2. speakers

A friend told me JBL DD67000 is actually very bad speaker, is it true?

According to him, those Tidal, Kharma, YG, Magico, Vivid G1, Grande Focal and German Physik are truely good speakers, JBL ain't no good...and his reasons: JBL is boxy, horny coloration as hell, zero imaging.

is this true?

Fiesta - Yes Vandersteen has been doing this for almost 20 years…. and with more than 9v
The amps use same tech applied to IC and speaker wires but 128 V
….
trade secret uses in other places…

The 9 volt batteries keep a constant charge on the capacitors in the crossover. Similar to a class A amp where the transistors are always on. (I think this idea came from Ed Meitner.)
