I bought it in Taiwan and for about 1 years , in these days I think it is not very good but it is also have good music to me, especial man's pop music .I have used a EL-34 tube amp and R-tec MC-100/ MP-150 for it , it does not make me disapointment . but I think it is not as good as B&W CDM1SE , but it costs only half of that , so I think its C/P is good enough .
