  • Dual-mono 200 V tube stage gives wide stereo separation and warm analog tone
  • 4 mm balanced and 6.35 mm outputs drive 16–600 Ω headphones with 5 dB or 15 dB gain
  • RCA preamp output adds tube harmonics to power amps or active speakers
  • Swappable NE5532 op-amps and 6A2 tubes let you tailor the sound signature
  • Full-aluminium chassis with six-mode LED glow and 10–30 s tube warm-up timer

Dual-Mono Tube Architecture

The LORDWORLD P5 is a desktop headphone amplifier with a dual-mono tube stage running at 200V for independent left and right channels. It provides a 4.4mm balanced output and a 6.35mm single-ended output. Adjustable gain settings of 5dB and 15dB support headphones from 16 to 600 ohms. A tube warm-up timer runs for 10 to 30 seconds.

Audiophiles who want tube rolling

This amplifier suits listeners who value analog warmth and the ability to swap 6A2 tubes or NE5532 op-amps to shape their sound. It also functions as a tube preamp via RCA outputs for active speakers or power amps. Buyers needing wireless streaming, Bluetooth connectivity, or DAC functionality should look elsewhere as this is an analog amplification stage only.

4.4mm balanced and 6.35mm outputs

The defining specification is the combination of a 4.4mm balanced jack and a 6.35mm jack driven by the dual-mono tube circuit. This allows direct connection to both audiophile and studio headphones without adapters. The adjustable gain structure ensures clean drive for low and high-impedance loads from 16 to 600 ohms.

Questions about this item

How often will the 6A2 tubes need replacing and are they user-serviceable?

The 6A2 tubes are user-replaceable and designed for tube rolling; typical tube life spans thousands of hours, and the 1030s warm-up timer helps extend longevity by preventing cold-start stress.

What limits continuous output during long listening sessions?

The 200 V high-voltage tube stage and dual-mono architecture set the thermal ceiling; sustained high-gain use at 15 dB into low-impedance loads will hit tube dissipation limits before the aluminium chassis does.

How much heat and noise does the P5 produce when left on all day?

The full-aluminium body acts as a heatsink for the 200 V tube stage, so the unit runs warm but silent — no fans, only the 1030s warm-up cycle and six-mode LED glow indicate operation.
