Dali and B&W are relatively hightoned both of them, and can make the nasty s' sounds, especially if they are paired with digital amplifiers. However, a strong second bid could be Wharfedale Evo 4.2 or Quad S2 Both English sounds, with the slightly warmer top
And all three are digital amplifiers - it may well be what you are allergic to, it is now not unknown to some people. ;-) A tender here could be Audiolab 6000a Play or 6000A + a Wharfedale Evo 4.2, it would be a really nice match, massaging the details, and still good with punch. EVO 4.2, however, is a relatively large compact speaker, so it is whether you have the space for it
But if you have it, you get some more at the versus the slightly smaller models, S-2, Z-1, 4.1 etc.
