Making further progress, TOPPING’s new flagship amplifier will be launched in late May!
Maybe musicians record with extra low distortion, in the hope that most people will play using systems that add distortion, to ultimately sound as they had intended ? Haha. Yes. That was my thought when I read @Monk 's review. I suppose it's possible that some audio engineers abstain from...
