UNTIL... I found the right electronics to drive them - which are the amps the designer demos them with - the Hegel amps.
I find that so amusing, as only a few years ago Alan Shaw was quoted as saying that his well fettled 1970’s transistor amplifiers were good enough for product development and that he didn’t think any worthwhile improvements would be made by upgrading. Something must have happened to clear away the fog.
Next thing he’ll be buying decent speaker cable..
