LESS BX2-PRO Specifications

 

BX2-Pro is LessFox Independent research and development, continued BX-2 & plus version, we have more extensive experience to improve portable full balance(C.A.S.T)CLASS-A headphone products。

Software: Design base on HI-END class KRELL's equipment C.A.S.T current circuit(Full balance current design), from the audio source to the output signal is a fully balanced design,  most of the hi-resolution audio equipment is using Current Mode,it improves ultra-high frequency responding,

 ; over capacitor signal passthought to reduce distortion and more natural。

Hardware: The whole machine are using a very rare perfect match transistor; volume control using TI company ultra-low noise PGA4311 volume chips; signal stage are using 4 pcs Toshiba 2SK170(99% matched)and 2SK5171/A1930 transistors(99% matched); VISHAY crystal resistors,

matched power transistor to make sure 4 channel conformity; CNC CU 24K gold plated case to improve highest level noise isolation; Made in Japan Pentaconn4.4 and Taiwan Fujitsu 3.5 socket to reach the Hi-End level。
