How absolutely not necessary? The Vandersteens were on my short list of loudspeakers and now to find out that unless I bi-amp, I will not get the best that I can get from the speakers is very depressing. I guess my search continues. It isn't that I can't swing bi-amping; it is more than I want to setup the best, non-complicated system for a modest investment. Bi-amping puts more time and energy into a system than I want to put in. My goal is to setup the system and forget about it and just listen. I have been researching and reading for many months now and it is beginning to wear me down. How do you guys do it? Honestly, I don't have the audiophile blood in me. I just want a good sounding system. Now what.
