Features

It integrates customized pluggable VU meters, retro military-grade vacuum tubes and a crystal-clear OLED screen. Not only add warmth to the sound but also vividly show the dynamic changes in the audio signal. Allowing you immerse yourself in a vibrant audio-visual feast as you delve into the HiFi world.

  • Luxurious Chipset Unleashes Peak Performance: QCC5125 Bluetooth chip supports APTX-HD and LDAC, achieving the highest 24Bit/96Khz transmission. The SA9137L USB chip and ESS9018K2M DAC chip handle PCM data up to 384KHz/32Bit and DSD256. The TPA6120 amp chip effortlessly powers headphones ranging from 16Ω to 600Ω. Besides OPA1656, 2PCS pluggable NE5532 op amps allow you to tailor your sound by swapping with various dual op-amps.

  • Authentic tube amplification and sound: the P1PLUS preamp circuit elevates the voltage to 100V, ensuring that the vacuum tubes operate at their full potential and delivering a warm and rich experience. The unique technology faithfully reproduces crisp high tones, lush midrange richness, and deep, rhythmic bass. Pluggable socket design allows for tube rolling and sound-shaping to customize your own sound.

  • Versatile audio inputs and outputs: the P1PLUS provides Bluetooth/ USB/ coaxial/ optical/ stereo RCA/ 3.5mm AUX inputs, and optical/ stereo RCA/ 3.5mm AUX/ 3.5mm headphone jack outputs, perfect for fulfilling all your home audio needs, also easy to create 2.1 or multi-channel audio systems by connecting active speakers, amplifiers, or subwoofers. Multiple devices can be connected and switched at one time to minimize cable-plugging hassles. 

  • Enhanced details elevate the P1PLUS to perfection: it features tone knobs allowing for precise tuning of bass and treble; with remote control to adjust all settings at your fingertips; and a Bluetooth reset button on the remote to prevent accidental connections; color-variable VU meter complements various listening spaces; the sleek aluminum-alloy CNC-molded body seamlessly blends retro charm with modern design.

Warm tips:
 
1. All analog audio outputs will work at the same time no matter what audio input is selected. While the optical output will only work when PC-USB inputs.  
2. Only USB input supports PCM 384Khz/32bit DSD256, coaxial and optical inputs only support PCM 192KHz/24Bit at the highest.
3. For win7, PC-USB only can be recognized when the driver is installed. For other systems, the driver is only required when playing DSD files.
4. P1PLUS default comes with JAN5654 tubes, can be replaced by 6J1, 6K4, 6J5, GE5654W, 6*1N, 6*2N, 6J5,6A2, etc. 
5. The volume / treble / bass of the three outputs (stereo RCA / 3.5mm AUX output and 3.5mm headphone jack) are controlled simultaneously.
