Yes this exact situation happened to me. I had an mv55 Conrad Johnson tube amp. I sounded glorious with my JM Labs Daline 2.1's, which were limited range speakers that went down to about 40 hertz. I put the mv55 on a pair of Wilson wp7s and heard a lot of grunge which made me think that Wilson's weren't so good. I asked the dealer who had let me do this experiment what was happening and he said that the amp was producing lower quality sound in the deep basd and that the Wilsons were now reproducing that where my JMLabs weren't.
So I don't know about better or worse, but if you have full range speakers you have to have higher quality electronics in the entire chain leading to it.
