Features
  • Dual-Mono Architecture: Each channel is powered by its own dedicated amplifier circuit, ensuring superior stereo separation and reduced crosstalk. Paired with a 200V high-voltage tube stage, the P5 headphone amp delivers rich, clean, and warm analog audio. This structure outperforms shared-path designs for a more immersive hi-fi listening experience.  
  • Versatile Headphone Outputs: Supports both 4.4mm balanced and 6.35mm single-ended jacks, making it ideal for studio headphones and audiophile setups. With an impedance switch, you can easily adjust gain levels (5dB/15dB) to match your headphones from 16–600Ω, ensuring optimal clarity.  
  • Works as a Tube Preamp: Beyond headphones, route the P5’s analog signal through RCA OUT to your desktop power amp or active speakers. Unlock rich tube harmonics and dynamic presence in your entire audio system—ideal for audiophiles and creators seeking vintage depth with modern transparency.  
  • Fully Customizable Experience: Featuring plug-in NE5532 op-amps and replaceable 6A2 vacuum tubes, the P5 invites you to fine-tune your sound. Roll your tubes or swap op-amps to craft your perfect sonic signature, no soldering required.
  • Premium Build with Visual Flair: Choose between a sleek full-aluminum chassis or retro walnut wood to match your style. A six-mode ambient LED system adds a visual glow synced to your music, while adjustable tube warm-up (10–30s) extends tube life and protects your headphones on startup.  
Warm tips
1.The enclosure of wooden version is crafted from solid walnut. Due to the natural variation in wood grain, the actual product may differ slightly in appearance from the images.
2.Input and output priority is as follows: Input – AUX > RCA; Output – 4.4mm headphone jack> 6.35mm headphone jack> RCA. If there’s no sound, please check priority and unplug unused ports.
3.10-30 seconds warm-up required. It is normal for there to be no audio output during tube activation.
4.High voltage inside. Please power off and disconnect P5 from the power source before replacing the op-amp or vacuum tubes.
5.P5 adopts 2PCS pluggable NE5532 op-amps, which can be replaced by dual op-amps such as 4558/JRC2068/2064/MUSE01S/2111 etc.
6.P5 is designed with pluggable tube sockets, default comes with 6A2 tubes, can be replaced by 5654/6*7N/6AK5/EF95/403B tubes.
