hORNS by Autotek out of Poland are outstanding as well, and not shouty in the least. I have the Symphony model @ 95db efficiency- have run it with 211 SET/Aries-Cerat Incito S preamp; and Grandinote Shinai 37-watt pure class A solid state integrated with equal success. The Beryllium compression horn driver is super smooth yet revealing, and as mentioned above, plays so well with a variety of good amplification- HIGHLY recommend you put this brand on your radar screen.
I have also been to Charney Audio in NJ a few years ago- the big Concerto speakers were quite good, however given the ultra-revealing nature, SET was mandatory to get the best out of it. Brian had an amazing custom Audio Note type 300B setup; preamp; and dac- and he built everything. His woodworking and metal shop in the basement are incredible as well- he is a true artisan and super nice guy as well. He even built the battery power supply and modded my excellent 47 labs Flatfish cd transport.
