Before you get too carried away, do the positioning thing. Then try different speaker wires. I was surprised with relatively inexpensive speaker cables from Ultimate that took over from the very cheap temporary ones when I had moved and required extra length. Solved a sibilance issue that I was convinced was the room.
sibilence....any cures out there?
I have recently accuired a pair of Nola Viper 1A speakers, while their performence is outstanding generally, the only problem is highlighted sibilence on vocals which is very annoying!!! Is this down to the speakers? Would a change of interconnects help? Any ideas from you guys would be appreciated greatly...
