Pravi dijamant i po mnogima ponajbolje zvučeće 300b pojačalo u obnovljenoj verziji. Kako ima ugrađeni volume pot, moguće ga je koristiti i kao integrirano pojačalo, a ako imate samo jedan izvor zvuka. Osobno, jedno od tri najbolja pojačala koje sam ikada čuo u 42 godine bavljenjem ovim plemenitim hobijem. Uparite ga sa Air Tight ATC-5 novim pretpojačalom 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.
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.
