Integrated amplifier
well above typical
Among the 59 integrated amplifiers in the catalogue, this one is well above typical.
A band places a component against its peers and carries no price. It is deliberately the only price indicator on this page: a second one, measured against a different set, would narrow the two together far enough to give the figure away.
NEW ENTRY (2026-05-12) per Tier 1 currency audit. Audio Note (UK) Meishu Phono Silver Tonmeister 300B — Level 3 SET integrated amplifier with built-in MM phono stage, shipping since late 2019. Hand-assembled by 28 full-time employees at the West Sussex Audio Note factory. Per Stereophile (Robert Schryer): "weighs about 65lb and started shipping in late 2019."
TONMEISTER DESIGN UPGRADE vs PRE-2019 MEISHU: The Tonmeister is a major redesign vs the original Meishu (1991-2018). Per Audio Note UK official: "The input and driver stage is very similar to that found in the JINRO, TOMEI and ONGAKU, with a 12AU7 and 5687 driving an in-house designed and manufactured inter-stage transformer for the best energy transfer, evenness and authority. This is the most important, fundamental upgrade over the original design." Also: new PSU (one mains transformer + one 5U4 rectifier + one choke), new output transformers designed specifically by Andy Grove. Per Dagogo (Constantine Soo): "I have never been much of a 300B tube amplifier fan... the Meishu Tonmeister is the best of both worlds — an amplifier capable of gentleness and politeness but can also bring it with rock and roll."
VALVE COMPLEMENT (Phono Silver Tonmeister): 1× 5U4G rectifier + 2× 300B DHT output (Psvane Hifi Series standard) + 1× 5687 driver + 1× ECC82/12AU7 input (Psvane Hifi Series) + 1× ECC83/12AX7 + 1× 6DJ8/ECC88 for MM phono. Silver Signature variant adds 1× ECC82 CV4068 silver upgrade. Common tube types — tube-rolling friendly. NOS Philips ECG 5687WB recommended for the driver position (per Stereophile).
CRITICAL ELECTRICAL FIT: 8W SET 300B mandates ≥93dB sensitivity speakers. Excellent partners: AN-E SPe HE (98dB), AN-J (94dB), Living Voice IBX-R3 (94dB), Klipsch Heritage (Cornwall/La Scala 95-99dB+), single-driver/horn speakers. POOR partners: BBC LS3/5a tier (83-84dB) and most modern compact-bookshelf designs (80-86dB). In cavity-constrained system context: NO cavity-eligible speaker in current catalogue meets the 93dB+ requirement (highest is Neat Petite Classic 87dB / PMC Prodigy 1 87dB) — Meishu Tonmeister is architecturally INCOMPATIBLE with cavity placement constraints. For free-placement systems, Meishu Tonmeister is among AN UK's most rewarding entry points to the Level 3 SET 300B world.
Assessed against 10 rivals across the sixty systems: it takes the slot in none of its 36 head-to-heads.
The dimension the engine names as the weakest link, counted across every head-to-head it lost.
