I have Eltax Concept 400 floorstanders in my main system. Objectively they are the weak link in my system however I like them; they seem to work well with my Quad 303 power amp. I think that really is the key, your speakers are one element of a system and, as such, need to complement other elements in the system. Conversely you might have a superb set of speakers and a superb amp, however if the synergy is missing it will sound like a crock.
The bottom line is trust your ears. If you are happy with the sound you are getting you've got it right.
