Pravi dijamant i po mnogima ponajbolje zvučeće 300b pojačalo u obnovljenoj R verziji. Kako ima ugrađeni volume pot, moguće ga je koristiti i kao integrirano pojačalo. Jedno od najboljih pojačala koje sam ikada čuo u 45 godina bavljenjem ovim plemenitim hobijem. Uparite ga sa Air Tight ATC-5S novim modelom pretpojačala i shvatit ćete da bitno bolji zvuk nemoguće je dobiti, makar potrošli višestruko veći iznos. Dodatnu magiju cine najbolje postojece cijevi, 300B Takatsuki made in Japan, koje su uz doplatu mogu naruciti.

The ATM-300R is the latest incarnation of a design that made its commercial debut in 1999, as the ATM-300—then as now, a single-ended amplifier that uses one 300B directly heated triode per channel to produce 8Wpc. The third product in this lineage—Air Tight’s second single-ended 300B amp, a limited-edition product called the ATM-300 Anniversary, was issued in 2016—the ATM-300R improves on its forebears in various ways. Perhaps the most significant of these is the change to a hand-wound, paper-wrapped choke coil for the power supply, in tandem with a hand-wound, paper-wrapped mains transformer—both designed and made in-house. According to Air Tight’s Yutaka “Jack” Miura, son of company founder Atsushi Miura, the new iron results not only in better sound but in slightly higher output: 9Wpc. Jack Miura also points to the new model’s redesigned power supply, and its use of a brand-new output-transformer design from Japanese transformer specialists Tamura.
