Thank you very much arthur and mbaudis, I think I will try Adams (I can buy them in shop offering one month to test and return if I not like them). There is now only problem which of them - A5X, Artis 5 or Artist 6. Hard to decide without to know how they differ sonically ... A5X looks as the same like Artist 5 (built-in USB DAC is irrelevant) but they can sound different (front basreflex and class D amplifier for woofer - is it better or worse ? hard to say). Artist 6 are more expensive, but they look elegant (and unstable, while so slim) and they have a bit more woofer area (2x4.5" is more then 1x5,5").
