Absolute perfection IMO I really dont have everything as it should be but the EMO and pio work very well together,I'm still tweaking my kappas with the dcx to get it all where it should be but when I listen to the Mains with just the EMO and the PIO it is clean , crisp , and really tight with power to spare when I just use the PIO no amp it seems muddled and somewhat dull now so the EMO is always on.
edit.I really need to be careful with the kappas,EP 2500,EMO,I just might have to touch up some joint compound here and there My HT has never been better and soon to come new speaks ,heck I have never even had surrounds ,rears and such just the fronts and my new kappas.
