Shanling EC ZeroT electronic tube portable CD player fever HIFI player Bluetooth HD desktop all-in-one

EC Zero T CD player reshapes the peak sound quality with luxurious configuration. It is the industry's first portable CD player with R2R + dual JAN6418 tubes, with better portability and aesthetics, the strongest sound quality under the same volume and weight, and the Japanese ALPS sliding audio potentiometer.

ECZeroT is the first portable CD player with R2RDAC architecture + dual JAN6418 tubes, continuing Shanling's classic and creating the peak of RunFi. Shanling's self-developed Kunlun R2R resistor array D/A module, 24-bit architecture, consists of 192 0.1% high-precision resistors. Compared with the common Delta-Sigma architecture DAC, the R2R architecture realizes pure analog conversion, making the sound like a mountain stream, crystal clear and moisturizing the heart.

ECZeroT is equipped with dual JAN6418 tubes, low voltage, low power consumption, and a specially designed anti-vibration structure. ECZeroT has strong anti-vibration performance and almost no microphone effect, ensuring the purity and clarity of audio output. The dual JAN6418 tubes and R2R modules provide more current and warm sound performance for the acoustic circuit, allowing you to encounter infinite charm and feel the lingering sound. Supports two modes: transistor/tube, to meet different usage needs.
Supports two mode switching
PTU mode: strong sound quality, solid and dense imaging
Tube mode: the sound is thicker and fuller, with a stronger sense of landing and weight.

TPA6120A2 high current op amp
Two TPA6120A2 headphone amplifier chips from Ti are selected. The chip has the characteristics of low distortion and high index, especially the fast rotation rate brings strong energy conversion efficiency, making ECZero1 headphone output easy. It is also equipped with Panasonic polymer low-loss tantalum capacitors, which are highly accurate and less affected by temperature, and have a long service life, making the sound performance more natural and smooth.

Battery lifemax large capacity 5500mAh lithium battery, supports DC power input
ECZeroT customized large capacity 5500mAh lithium battery, say goodbye to power anxiety, up to 8 hours of long-term battery life so that you can explore wonderful music during your travel. ECZeroT also supports DC external power supply, and the thrust soars when using external power supply,
Strong sound waves, sweeping around your ears.
8 hours-3.5mm single-ended battery life
7.5 hours-4.4mm balanced battery life
