Does the Darkvoice 336SE drive the Audeze LCD-2 Classic?

Computed from rated specifications · target SPL 110 dB · load 300 Ω

Verdict

Ample

The Darkvoice Darkvoice 336SE drives the Audeze LCD-2 Classic with ample headroom (~15.0 dB headroom at 300 ohms; needs ~7.9 mW, delivers 250 mW). Note: this OTL tube amp's high output impedance (100 Ω) interacts strongly with this low-impedance (70 Ω) headphone, which can audibly alter its tonal balance. OTL tube amps are best paired with high-impedance (250 Ω+) headphones; this is a less ideal match.

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 caution

This OTL tube amp's output impedance (100 Ω) is high relative to this headphone's 70 Ω impedance (ratio 0.7×). OTL tube amps are best paired with headphones ≥ 250 Ω; this combination may cause audible tonal coloration.

Planar driver note

Planar-magnetic headphones can have high current demands that are not fully captured by the power headroom model. Even with adequate headroom, some solid-state amps may struggle to deliver sufficient peak current for transient dynamics. Prefer amps rated for low-impedance planars.

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.
