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 adaptive impedance switch, it automatically tailors gain levels (5dB/15dB) to match your headphone of 16–600Ω and unlock 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.
