Next week I will be getting a pair of kef q900s. I was wondering how I should set them up. I have a emotiva umc 200 preamp. I also have both a adcom 535 and a emotiva upa 500 amplifier. Should I bi amp the speakers with both amps and if so which amp should power the upper vs lower frequencies. If I should not bi amp should i use just the emotiva or just the adcom to power the speakers. Thanks any thoughts would be helpful.
