They also have the 0 db gain 8 port model, called the EDA 2802. It has an amp but only to bring up the split loss to 0. I have one and it works fine but the 4db gain helps me out a bit more so I actually use the eda-2800.I just ordered the 8 port version, and I'm returning the 4 port. After listening for a while more last night, far too much is being over driven. Thanks again for the advise 737mech, will let you know about the next round of this (mis)adventure!
