@jjss49 decooney i did not... long long story with my efforts over the decades trying to find a high efficiency speaker i can truly live with long term ...but despite my efforts, i continue to strike out after so so many at bats... just too much transducer distortion for my ears in some form, in each case.
If you have not tried it yet, the new (redesigned) Klipsch Cornwall IV is known to be a bit of a microscope for noticing differences in component changes. Paired with a nice 300B amp like yours, could be kinda fun. I helped a few friends design/build cabinets for three pairs of revealing Altec Onken replicas, too big for my place. But, would be nice to try some Cornwall IVs. I can imagine they could reveal differences in dac testing and sound nice too. Checking with my local dealer to go listen, I’m interested in hearing the midrange they offer. A big fan of the old style...wall of sound for amp and dac testing... :)
