Where to start, How about Hi and thanks for taking the time to help me with my dilemma. Well I am upgrading and revamping my home audio systems. In the same room I have a Klipsch F3 Synergy 5.1 sorround sound. I primarily use this system for blu-ray, everyday TV watching and DVD/Blu-Ray live concerts 5.1 is pushed by a Onkyo a/v reciever. My second system is a bi-amplified set of JBL 4350 Studio Monitors; they are beasts. Primary use for the JBL is for stereo cd listening, source was a 300 disc cd changer. JBL are pushed by 2 amps. Tomorrow im selling the 300 disc cd changer and purchasing the Sony BDP-CX960 Blu-Ray changer. Then my Blu-rays, DVD and CD's will be in one unit. Im selling the Preamp that runs my JBL and leaning toward purchasing the Emotiva XMC-1 to replace it. So getting to the question I want to incorporate the JBL L/R in a 5.1 set up and ill be using the Klipsch center and surround speakers along with its subwoofer. This set up will be used only with the BDP-CX960. Once I revert back to everyday satellite TV watching I want to switch on the full Klipsch 5.1 set up that I originally had. I basically want to get rid of the Onkyo and integrate the new PreAmp for both set of speakers but selecting specific speakers in the process as described above. I will be adding a Emotiva XPA-5 to push the Klipsch 5.1 set up. I need help in configuring this and I know im going to probably need additional components or possibly change the Emotiva products to accomplish this daunting task. Ive thought of some sort of switches but I need more detailed help, I greatly appreciate any help as this is the step before i seek a professional to come to my home to run me an estimate. I have a video on youtube, if you go to my channel (kwazykilla87) you can see my set up. If any questions please ask and thanks again!
