Modern Tannoy is true to their heritage and still can sound amazing depending on the price point and equipment used. I've recently purchased some of their low budget stuff, entry level dual concentric 6 " driver based floor standers. These speakers retailed for about $1200, so nothing crazy.
The sound is clearly quite good for the price point. I bought these because a few years ago I bought a pair of their smallest concentric driver bookshelf speaker. It was an impulse buy and I put them in the bedroom system which was seldom used.
Fast forward a couple of years, when I started buying used speakers as some kind of strange hobby. One day I thought of the small Tannoys(Revolution DC4) and thought I'd compare them to a few pairs I had from Paradigm, Polk, and Mirage. These little fellas blew every single set of speakers away. I was seriously impressed, and it was the reason I stopped buying old speakers, and I have sold off most of them.
Tannoy still knows how to build a good speaker.
