How do they sound? Here are what factory said after A/B audition by audiophiles at pre-launch:

ACME Supreme 300B vs. Western Electric 300B (1998 production): “Clarity and transparency are stunningly better on the Supreme series, you can almost touch the singer in the sound stage. Scarily live! For mid-range that Western Electric 300B has always been lusted for, ACME Supreme 300B doesn’t lack any texture, fullness, richness, and tonality. Audiophiles say that ACME wins hands down on depth and width of sound stage comparing to Western Electric 300B (1998 production)! It is of all the classic vintage sound signature – the absolute analog sound! “
