Does the Darkvoice 336SE drive the Beyerdynamic T1 (3rd Gen)?

Computed from rated specifications · target SPL 110 dB · load 600 Ω

Ample OTL-compatible pairing

The Darkvoice Darkvoice 336SE drives the Beyerdynamic T1 (3rd Gen) with ample headroom (~11.0 dB headroom at 600 ohms; needs ~10.0 mW, delivers 125 mW). (Amp power at 600 ohms is estimated from its published figure at a nearby load.) This OTL tube amp suits the headphone's impedance (600 Ω) — a classically compatible pairing for high-output-impedance tube sources.

OTL tube amp using 6N5P output tubes. Manufacturer page (Apos, analogmetric) states only 'Power handling capacity: 1 W' with no load specification. Power figure of 250 mW @ 300 Ω is a conservative estimate based on OTL topology similar to the Bottlehead Crack; treat as approximate. Output impedance of 100 Ω is estimated from OTL/6N5P tube topology — manufacturer does not publish this figure. 600 Ω derived from 300 Ω. · Source ↗
Impedance compatibility

This OTL tube amp's high output impedance (100 Ω) is a good match for the Beyerdynamic T1 (3rd Gen)'s 600 Ω impedance. The impedance ratio (6.0×) falls within the recommended range for high-output-impedance tube sources — a classically well-matched pairing.

Specification confidence: low

One or more amp specifications (power output or output impedance) are estimated rather than published by the manufacturer. Treat this pairing's verdict as approximate.

Power figure note

The amp's power at 600 Ω was not published directly — it was derived from the voltage ceiling at a published lower-impedance load. The actual delivered power may differ modestly.
