The question came to me before the answer. My answer will follow.
Please be as detailed as possible including listening room details. Any system and vintage is eligible: home; custom install; dealers, distributors, manufacturer's or even shows.
Heihei's Pacific 242 with audionet stern and Heisenberg surprised me too and can join the list if I get to hear it again. Has been two years now. That works only with the Pac 242 into the audionet imo
One clearly stands out to me: Emile’s demo system at Taiko Audio.
Taiko Extreme with Audioquest Hurricane PC, USB Intona Ultimate to Lampizator Pacific (not sure which PCs or ICs on DAC through amps)
Alieno preamp and amps
Alsyvox Botticelli (or Caravaggio?—2 panels each side) not sure about cables to crossover or cross over to speaker
Dedicated room ~18’w x 24’d x 15’h with ~15% surface coverage absorption and 15% diffusion.
There’s a pic somewhere on here of the room, but I can’t find it. Unfortunately I didn’t take any pics.
