| dna.amp_character | warm | AI draft0.25 | Черновик: «традиционная музыкальная подача Marantz», модули HDAM-SA3, класс AB — в прессе дом Marantz обычно описывают как тёплый/музыкальный; прослушиваний, обзоров и ответов специалистов по этой модели нет |
| dna.warmth | 6 | AI draft0.25 | Черновик: по той же инференции, что и amp_character (дом Marantz); свидетельств нет |

| room_area_m2 | 10–20 m² (8–30) | inferred0.25 | по мощности (2×50 Вт/8 Ом, как у Audiolab 6000A) и §4.9.17: 88-дБ АС — до 40 м² при 100 дБ пиках без запаса; ответов специалистов по комнатам нет → консервативно 10–20 м² (опт.), 30 макс. |

A class-AB integrated, 2 × 50 W (8 Ω) / 2 × 65 W (4 Ω), with HDMI ARC, an MM phono stage, an ESS 24/192 DAC and two-way aptX Adaptive Bluetooth — the PM6007 successor for a compact vinyl + TV + phone system. Suits mid-sensitivity bookshelf speakers in rooms up to 20–25 m²; the sound character is not yet confirmed by listening.
