agree with the idea that the mcintosh amplifier has excellent synergy with the B&W
speakers.
i really enjoyed hearing this combination. the smooth deep sound of the mac amp brought deep full range bass the b & w are capable of. also the resolution of the diamond tweeters was spell binding, vocals sounded phenomenal. there is a reason these speskers have a high resale value and they do!
i have heard the tannoy many times and they can sound very good but never great.
the midrange was never best in class transparent, the treble could be slightly edgy and the styling looks good if you like that out of date look, horrible if you do not.
