Mark Levinson № 632

Class A/AB discrete dual-monaural stereo power amplifier.

Evidence checked: 2026-10-11. Manufacturer/distributor documentation; no independent SoundPath Lab test.

What the documentation establishes

• Two balanced XLR and two RCA inputs; two pairs of speaker binding posts per channel.
• Analogue power-amplifier role; USB-A is a service connector, not an established audio input.
• Manufacturer documents and multilingual manuals are linked on the model page.

Best for

A separates system already equipped with a suitable preamplifier.

Avoid if

You require a complete streamer/DAC/integrated amplifier or a fully conditioned power comparison.

Limits and unresolved details

Regional wattage claims lack complete comparable test conditions and are not assigned as verified rated output.

Support and purchase checks

Confirm the complete regional model, required cables and external components, current manual/firmware, local warranty and actual dispatch with the official channel. App and streaming-service support depends on current versions; paid services may require subscriptions. A planned release or an order button does not prove local stock.

Keep an existing system that already meets these connection and use requirements. No measured sound-quality upgrade, reliability score or automatic purchase recommendation is assigned.
