l am going to come on this thread a bit left field, l just brought a pair of Tannoy Mercury M20, for a decent price- always loved the look of them when starting out in this business, years ago, anyway cleaned them down, drivers and cabinets, tightened all the driver screws, warmed them up(they were freezing cold) had a listen.. mmm not bad not bad at all, open,airy,dynamic and very dynamic, with a thick bass bump, so left playing whilst doing other stuff, came back for a listen, each time doing so, sound getting a little better
Well this morning listening to them

, they sound bloody amazing, even more open, so, so musical, dynamic, the bass thump has gone, replaced by, kick drum that hits you in the chest, and they are so sweet, smooth, with the imaging very excplicit, crickey these are good
