Before everyone casts stones allow me to acknowledge I've read tons of posts on the subject. Let me further state, I don't want to argue the semantics. What I am going for with this thread is the idea of frequency disturbance on speaker wire. \nLong story short...my RTi A7's were a disappointment and prompted work. After a frustrating few days I ordered a Parasound 2350 amp, against all advice I received from the esteemed members here, and promptly returned it with a loss of abt $60 for the trial. Needless to say...listen to those who know. After that I set about the basics...wiring. Basically, any signal wiring I have seperated from AC power and have also included a drain to system ground in all pathways. That really made no difference, but it's good as a preventative measure.\nThroughout I have been reading about bi-wiring\/bi-amping. I avoided it as nearly all posts relegated it a waste of time.\nThis weekend, unfortunately at the end of a holiday weekend, I finally tried it after reading a 9 year old argument on the subject. One poster pointed out the frequency effect between low and high and the impact on a single cable feeding both. That resonated. It was logical so I tried it.\nWire the same, same length, wired up and the Onkyo TX RZ820 setting for bi-amp changed to "yes", (bi-amp is Onkyo's reference not mine).\nMarked difference. I increased clarity at volume and overall quality. The low end is punchy and the high is not distorted at volume as it was before. The mid is clear, defined...none of it perfect mind you...far better out there, but the improvement is incredibly.\nI will continue with the basics, wiring, while I find the better system. Still sub shopping. \nIn the meantime, any ideas on if the frequency between low and mid\/high actually create issues in the high range? Or throughout.
