Balanced XLR Headphone Amplifier

The LORDWORLD H2 is a desktop headphone amplifier built around a balanced XLR input for clean signal transfer from computers, DACs or CD players. A pluggable 6N3 vacuum tube adds a warm, sweet character to the sound. Dual TPA6120 chips drive headphones from 16 to 600 ohms with independent L/R balance and adjustable gain. The black aluminium chassis includes an LED status display.

Upgrade From Single-Ended Sources

Replacing a basic single-ended headphone amp or onboard audio, the H2 adds true balanced XLR connectivity and tube colouration for greater separation and a richer midrange. The jump is worthwhile when your source gear offers XLR outputs and you want the harmonic texture of a 6N3 tube alongside solid-state drive capability. It is not suited for listeners who need wireless streaming or integrated DAC functionality.

XLR Interface Practical Limits

Balanced XLR on the H2 accepts line-level signals from compatible sources but provides no digital conversion or network features. The amplifier requires the included 12 V DC adapter and does not operate on battery power. Headphone impedance coverage spans 16 to 600 ohms with a 6.35 mm output jack and a 3.5 mm adapter supplied. Buyers needing Bluetooth, Wi-Fi or optical inputs must look elsewhere.

Questions about this item

How much desk space does the black aluminum alloy chassis need?

The compact desktop amp sits on a shelf or desk with room for its rear XLR input, 6.35 mm headphone jack and DC 12 V power socket; allow a few centimetres behind for cable bend radius.

What is the first step when setting up the H2, and what do users often skip?

Insert the two supplied 6N3 vacuum tubes into their sockets before connecting the DC 12 V adapter; skipping tube installation leaves the amp mute and can stress the dual TPA6120 chips.

When will the 6N3 vacuum tubes need replacement, and how is it done?

Tubes typically last several thousand hours; when brightness fades or sound dulls, power off, let cool, pull the old 6N3 tubes straight out and press the new pair firmly into the same sockets.
