[Tube Heat, Diatone Sound] DS-800Z × WOODHAM KT88 × YAMAHA GT-2000 — 5H Late Night JAZZ BGM

The warmth of vacuum tubes, the Diatone sound. A walnut-and-brick Anglo-Japanese jazz café where Glasgow tubes meet Tokyo precision.

Tonight's reference: Mitsubishi Diatone DS-800Z (Japan, 1994) — a 3-way sealed bookshelf representing Mitsubishi's audio peak — driven by C.R.Developments WOODHAM KT88 (UK, 10th Anniversary), a British KT88 push-pull beloved by jazz listeners for its body and headroom. The vinyl front: Yamaha GT-2000 + YAL-1 auto-lifter (Japan, 1982, list ¥147,000, now ¥278,000+ on the used market) — the heaviest, most uncompromising Japanese-domestic DD turntable Yamaha ever built.

Five hours of deep, audiophile vintage JAZZ BGM.

🛠️ Tonight's Reference System ─────────

【SPEAKERS】 DIATONE DS-800Z (Japan, 1994)
A 3-way 3-driver sealed (acoustic suspension) bookshelf from Mitsubishi's audio peak. Aramid-honeycomb mid + 27cm woofer + dome tweeter. Response 32Hz–32,000Hz, sensitivity 91dB, impedance 6Ω, 25kg per cabinet.
DS-800Z embodies late-Diatone philosophy: sealed loading for the flattest, most articulate bass — not the most. Where bass-reflex cheats with port tuning, sealed cabinets demand a properly engineered driver and a brick of a box. Famously bandwidth-flat with no holes from 32Hz to 32kHz.
Voiced for upright bass weight and saxophone air — sealed loading keeps the low end tight and the soundstage stable even at low volumes.

【POWER AMP】 C.R.DEVELOPMENTS WOODHAM KT88 (UK, 10th Anniversary)
A British KT88 push-pull from C.R.Developments, the boutique British tube maker founded by Christopher Robson. WOODHAM KT88 is the company's 10th Anniversary commemorative model: KT88 × 4 in push-pull, 12AX7 × 2 driver, 5687 × 2 phase splitter. List ¥328,000.
KT88 (upgrade of the classic 6550) is the tube of choice for jazz — its top-end air and midrange body suit acoustic instruments better than any other beam tetrode. Period reviews praised its "clear yet weighted" presentation. Roughly 14 years between domestic-market re-imports — a true rarity.

【TURNTABLE】 YAMAHA GT-2000 + YAL-1 (Japan, 1982)
The crown jewel of Japanese-domestic DD turntables. GT = "Gigantic & Tremendous" — Yamaha meant it: 5.8kg platter, 28kg total mass, quartz-PLL bi-directional FG-servo direct drive, 2kg·cm starting torque. Heavier than most professional broadcast tables.
The YAL-1 auto-lifter is a precision tonearm-return mechanism that lifts the cartridge cleanly at end-of-side — a luxurious touch found only on truly serious tables. ¥147,000 in 1982; today mint GT-2000s trade at ¥278,000 and rising. Nothing in the JDM lineage matches its build quality and rotational stability at any price.
Tonight, GT-2000 supplies the planted low end; WOODHAM KT88 colors it with British tube glow; DS-800Z resolves it with sealed-cabinet precision.

🎵 Music Style
Slow tempo · upright bass · saxophone · piano · dark · deep · heavy bass · instrumental
British tube warmth meets Japanese sealed precision — natural body, glowing midrange, planted bass. NOT a busy daytime cafe BGM. Designed for after-hours stillness, late reading, slow drinks, or restful sleep.
