Descriptions:

> T'ang-ku-Ia Module 
>The creation of Tang-ku-la module shows our determination to pursue excellence and constantly challenge the physical limits of performance. 
> The Tang-ku-la Module uses a brand new three-stage feedback circuit technology. It reduces circuit noise and high-frequency distortion, thereby increasing the dynamic range of the power amplifier to 151 dB. This technology also significantly lowers the heat produced by circuits, further boosting the reliability of the circuits, extending service life, and effectively diminishing thermal noise. 

> Exquisite Detail Reproduction in Music 
> The B100 boasts an impressive DNR and SNR. Whether it is subtle note changes or complex music levels, B100 can accurately capture and truly reproduce. 
SNR 151dB 
DNR 151dB 
Actual noise level <0.3uVrms @G=L

> Ultra-low Distortion Reproducing the Original Sound 
> The B100 boasts an unprecedented low distortion rate, with THD+N < 0.00008%, which is only 16% of the distortion level of the PA5, far surpassing the industry average. Such low distortion ensures that all details of music or other audio content are reproduced with high fidelity. 

> Low distortion while outputting high power 
> With a THD of less than 0.00007% at 40 5W and less than 0.00007% at 80 5W, the 8100 reaches a performance level that rivals the flagship DAC ES9039SPRO, significantly improving the accurate reproduction of audio sources. The B100 has a very wide working range with low distortion under load. Even in the common use of 1W-100W outputs with 4-ohm loads and 1W-50W outputs with 8-ohm loads, B100 still control the distortion around 0.0001 %.Provides three gain adjustments of H/M/L. 

> Suit combo
> Both the E70 and E70 Velvet DACs feature preamp functions and share a highly unified design language with the B100 power amplifier. The signal transmission between the DAC and the power amplifier can be achieved via XLR, TRS balanced cables or RCA cables.

> 12V Trigger
> The B100 amplifier is equipped with a 12V Trigger input interface, which allows for linked power on/off with other devices. This means that with just one power on/off action, you can simultaneously turn on or off all devices that support this feature, greatly enhancing usability.
