Great sound, quality materials.



re: SU-VX600

I've recently purchased an excellent second hand su-vx600 unit and I'm pretty satisfied with its performance.

I already have a pair of JBL Control1 (8Ω) + 1 JBL SB1 (subwoofer 4Ω) connected in the way JBL docs recommends (amp connects to SB1 which connects to satellites Control1). As far as I could understand this configuration has an impedance of 6Ω.

On the other side, I also have a pair of Pioneer CL-70 hi-fi speakers that I wish to attach to the amp.

The vx600 has the following speaker modes A, B and A+B/bi-wiring, so JBL speakers are attached to A connectors and Pioneer speakers to B. All sound pretty good but I'm not sure if the impedance is ok in order not to damage neither the amp nor speakers.

Does this configuration sound good to you? What do you think of attaching monitor and hi-fi speakers at the same time?.

Thanks in advance.
