I had the Carrera’s and could not tame the beryllium tweeter. Harsh and bright in more than a few song segments.
Two different houses, three different rooms. This was with Odyssey Audio hot rodded Khartago amp and Candela pre with Amperex 7316 pq tubes. Also had Ascend Acoustics Sierra2’s with a RAAL ribbon tweeter with same gear. Sweet as could be.
I personally would go with the Carbons. Beryllium just not for me. With that gear anyway.
