New review written in closing BLOG of Japan
B&W 802N vs BOSE M3 (Price $12700 vs $400)
M3 is the above in the quality of the bass in a near point . However, it is complete victory of 802N in high power in a far point. Another is a point near by a low volume and it is even. However, M3 is a poor balance by the bass, worsens by the source, and improves. The phenomenon of the volume's falling immediately after the bass is released has occurred when M3 is high power. Therefore, if the output is suppressed and used, M3 might be the best selection.
