SILVER CUBE

Lehmann Audio's flagship MM/MC phono stage — discrete Class A without global feedback, Mundorf tin-foil capacitors, WBT Nextgen sockets. The Silver Cube is Lehmannaudio's reference phono preamplifier and the pinnacle of the brand's phono engineering. The two-chassis design — a dedicated audio unit and a PWX II power supply — houses a fully discrete Class A output stage with no overall negative feedback, fed by the quietest input stages Lehmannaudio has ever produced. The RIAA equalization network is built around high-grade Mundorf tin-foil capacitors and mica capacitors in the input section — the same premium passives used in the Decade Jubilee — ensuring absolute tonal accuracy. WBT Nextgen RCA sockets minimise contact resistance and connector coloration. Vibration-damping 3S Device Feet isolate the unit from the supporting surface, and the high-mass aluminium enclosure doubles as a heatsink for thermal stability. Gain: 36–66dB selectable; input impedance: 47kΩ/1kΩ/100Ω plus custom; SNR: 78dB MM / 69dB MC; channel separation: >80dB. Audio section weight: 2.25kg; PSU: 2.8kg.

Technical background

The Silver Cube's passive RIAA network uses Mundorf tin-foil capacitors — selected for exceptional signal transparency and dimensional stability. The discrete Class A output stage operates with zero overall negative feedback, allowing the circuit to operate in its most linear region without correction loops. WBT Nextgen sockets provide reference-quality signal connections with minimal contact resistance, and the separate dual-output power supply isolates the channel supply rails completely.

Design story

The Silver Cube represents Lehmann Audio's unconditional best — developed in Cologne over three years of circuit refinement and listening evaluation without cost or manufacturability as constraints. Every component was selected after critical listening trials, and the passive RIAA topology was finalised after systematic comparison with every alternative approach. It is the answer to the question: what is the best phono stage Lehmann Audio can build?
