I think we could be dealing with two different potential
situations here 1) It is not possible to have significant problems in a
system and have some recordings sound great especially when they are
known great recordings. You could change some of the components in the
system and improve the sound but the fact that some great recordings
sound great is meaningful. 2) you could be chasing recording quality
and the only way to deal with that is to use tone controls on the
recordings that need them or dumb the whole system down to the point
that everything sound OK by trying a speaker with many drivers that
smear themselves, a dip in the mid range, plenty tweeter(s) and up in the
bass that play loud as for some audio enthusiasts enough volume cures
all. I would sort this out before spending any more money because even
though several hundred thousand of these speakers have been sold they
are not for everybody. If you decide to keep the 2Ce Sig’s I can help you get the most out of them cost effectively.
