Need help: Tannoy or B&W?

What’s your system ,having sold Audio for decades 

room size, cables, Amp,preamp front end need to know B&W like current 

not so much with Tannoy Totally different character type of speaker I sold both while in the U.K , B&W more dynamic detailed ,Tannoy a bit more laid back forgiving  that is why what you are looking for is so vastly different in the 2 Loudspeakers  the older B&W is for sure more detailed pronounced ,it could be tough if not tailored  by equipment or cable factors  and room treatments .That is a tough one  .

Neither - without knowing the rest of the system.

I’ve had both and both are excellent speakers. IMO you can beat Tannoys for soundstage and imaging. In my main system I’ve settled with Tannoy Churchill’s with super tweeters. I can literally walk around the room and get great stereo imaging. They are smooth, very efficient with beautiful midrange and visceral in the bass range when called for. They are the only speakers I know of that can be both intimate and thunderous. I can’t recommend them enough.
