What I find interesting is that many say they like "speaker A warm lowend" or speaker B crispy treble" and so on. That, to me, looks like they like the speakers coloration, but in the end, most get tired of it. That's the problem, IMO. That one looks for a speaker that have something instead of looking for a speaker that have nothing! A speaker that have so little own signature over the sound that you can only say "I like that I don't hear the speaker, just the music". I truelly believe that is a speaker that will win in the long run.
I must say that if someone asked me about my speakers, that I have had for the past 14-15 month now, how they sound, I would have to say, nothing. I have still not found ANY coloration that give a little sameness over the sound. Maybe there is something, but I have not found it yet. Like today, some friend came over to listen to my system and we did play a lot of different music and recording qualities and it is scary how different everything sounded. One guy even asked me if the version I played of Razor's Evil invader (old trash metal) was a remix, it sounded so different than at his place.
I'm not saying that my speakers are the best in the world and have no coloration at all. All I'm saying is, I have not heard any sameness to the sound, all music sound extremly miscellaneous and I have not found anything better. Maybe I will, maybe not. All I trying to say is; look for a speaker that don't stand out in any way. Not bright, not muddy, not forward, not laidback, not any sameness at all. If the music, even within the same album, really sound very different on them, maybe the coloration is very low = neutral speaker. And happy hunting
