Full resistance network, discrete R2R DAC
Innovative 24 Bit full resistance network discrete R2R DAC portable player.
One over ten thousand
Hundreds of one-millionth of a resistor carefully selected to form a discrete R2R DAC network.
R2R the beautiful sound can also burst
The whole machine is equivalent to using 8 PCM1704K chips in parallel for ideal dynamics, and R2R the beautiful sound can also burst.
0 background noise
The SNR of the whole machine is higher than 123dB, 0 background noise, and good news to low resistance balanced armature earphones.
Simple non-touch operating system
Less interference, less power consumption, leaving more power for artificial circuits.
Optimize Bluetooth with protocol stack
A normal Bluetooth clock is a clock that is recovered after parsing data received wireless. The Bluetooth clock of P6 is directly generated by the stop-moment crystal vibration of P6 processed by FPGA, and then the parsed audio data is aligned to the accurate clock generated by FPGA and sent to DAC for lower jitter.
Volume control system
Self-developed lossless - electronic switch matrix volume control system, lower signal loss, easier to use.
The original sound reproduction
Full resistance PCM,DSD native decoding, original sound reproduction.
Architecture advantages, sound characteristics
Because of the advantages of the R2R architecture and the flexibility of the discrete components, the sound of the P6 can be particularly fresh and natural, delicate and mellow.
Sound is the whole pursuit of P6
Although the thrust is great, it is particularly friendly to the earphones. In particular, it enhances the control of the balanced armature earphones while meeting the demand of high output current, and it also needs to achieve a natural stretch of hearing.

This is a little player with amazing clarity and deep sub-bass responses. What really makes this player different and unique is that it sounds so natural and organic. You hear pin prick clarity and resolution on treble without being splashy. No hint of sibilance but very smooth. Not sure if it is due to the nature of r2r register ladder design but P6 requires at least 250 hours of burn in to sound optimal. After substantial burn in, I got a lot better treble and bass separation. Also appreciate the responsiveness of Musicteck and L&P in my inquiry. They recently provided the firmware to support 1TB SD card and 12000+ file sorting capability.
