I've heard of them, but haven't experienced them in person. If you decide to resell them later, it might be more difficult to sell these than one of the more "hot ticket" tube amps/preamps.
Heard (of) Audio Electronics Supply?
Anyone heard, or heard of, AES? Website states subsidiary of Cary Audio. Offers some very reasonably priced tube amps and preamps, assembled or in kit form. Thinking of a foray into tubes, but not ready for the sticker on Cary gear. Will be mating with ProAc Studio series speakers. Any comments?
