    Thank you for your words. I am sorry to comment that I do not have the Shanling UA2. Well, actually I don't have any Shanling, nor have I been able to test it on any Tour in my country. :sweat:

    Reply to review by 'cqtek' on item 'TFZ Live X'

    It is clear that the Live X is not twice as good, even if it costs twice as much. Both have similar tuning. But, the low end of the Live X is more physical and punchy and the high mids are smoother and with better quality. The high end is clearly better, the treble is very good.
