I purchased Muzishare X7 MKII upgraded version from China-hifi-audio. It came with 4 x KT88 , 2 x 12AU7 , 1 x 12AX7 , 1 x 5UR4 They all have Muzishare name on them. Should I try to upgrade them? I am a cost sensitive beginner tube user. I am just curious.
Just got the Muzishare and so far so good. Sounds nice. I will do some tube rolling. First the smaller cheaper tube including the rectifier then later the outputs when i decide which brand.
