XA6800SE合并式放大器前级电压放大由原来的双运放OPA2604改为一个声道一只顶级单运放OPA637,耦合电容则使用了美国MIT电容。后级放大与XA6800一样,同样是单端放大电路,只是末级输出功率管由原来的每声道两对摩托罗拉双极性金封管,改为三对英国产音响专用的金封MOS-FET管,在保证低频推动力的基础上,使中高频更加细腻通透,具有胆机的味道。并且全
XA6800SE merger amplifier preamplifier voltage from the original dual op amp OPA2604 changed to a channel a top single op amp OPA637, the coupling capacitor is used in the United States MIT capacitors. Amplifier and XA6800 after the same, the same single-ended amplifier circuit, but the last stage of the output power tube from the original two pairs per channel Motorola bipolar gold seal tube, replaced by three pairs of British-made audio dedicated gold seal MOS-FET Tube, on the basis of ensuring the driving force of low frequency, make the medium and high frequency more delicate and transparent, with the taste of tube amplifier. And all
