I own a Yaqin MC-30L . I love it! It has lots of clean power with great build quality. I’ve not heard a Reisong A10 , but it has good reviews stating its midrange is good, but can lack power and some bass output. The Yaqin MC-100B with its stock tubes should give you plenty clean power, but the Reisong A10 may not even with its upgraded tubes. If power is not what you want, then both will probably be okay. I find power is good. I like my low power components, but for serious listening I use my high power stuff including tubes. I’d buy the Reisong A10 for its enjoyment if I already owned the Yaqin MC-100B, but that’s me and we’re all different wanting things, so I’ve learned taking and giving advice can sometimes not be good, but I really like my Yagin, so I replied.
