I visited Stereo Buyers' Brooklyn, NY headquarters to get a first-hand look at some vintage audio, and there were aisles and aisles of the most rarified gear to drool over. Not only that, owner Adam Wexler had a tasty vintage system ready for my listening pleasure: There was a magnificent Marantz Model 7 stereo preamp, rarer still a pair of Marantz Model 2 mono power amps in the center rack playing JBL L300 Summit speakers. It would be an understatement to say the sound knocked me off my feet! It sounded sweet and oh-so musical. The tall Red Rose Revelation R1 tower speakers lurking behind the JBLs weren't playing, more on them later.
