First of all: the Auto Standby is not so bad, but loving not for everyone! For classical music listening, especially when after many kettledrums long silent violin pieces come, I think that's not bad off, we so annoying the noise is not. But the nice thing about this precious piece: it is not intrusive, the bass is so clean reproduced that they only feel, not hear, incredibly impressive. But important to adjust the input frequency and the playback level really take our time, not over the target overshoot, then that sounds terrible. Let 105 Hz and 55% level, and on "nor": My tip for classical music and soundtrack. A beautiful device that I enjoy, when it was leveled correctly.
