Furthermore, I refer to my review at Bowers + Wilkens t7.
now I have a week long tested again to b + w t7 and the Bose SL3 and the brave 855S.
it remains at the 2nd, more extensive audition with this is that the most balanced BeoPlay plays the + w and vote for acoustic instruments is very good b.
Bose is a bose. much much treble bass and recognizing the efforts to a more neutral sound. but balanced is still not sounded.
the honest is extremely difficult and a very pleasant speaker without sensationalism.
Ranking: BeoPlay a2 -> b + w t7 -> brave 855S -> bose sl 3
but certainly the requirements are always different; as well as the sense of hearing.
