The correct speaker placement is in itself incredibly important as to audio reproduction itself, but has nothing to do with the quality of the interconnects being used, which are also another factor necessary to achieve one's goals. Anyway they cost money. How much one is willing to spend is thus another factor to deal with. My approach is to find the very best product that I can personally afford. Thus I am presently using MG Audio Design interconnects. The same can be said as to speaker wires, power cords, plus power conditioning devices. Altogether they can add up to a serious amount of money, but on the other hand are the price of achieving what is possible. It is just that I can not afford what Michael Fremmer is himself is using on his own audio system so I try to find lower cost alternatives. But if one ignores the subject itself, they will never, ever achieve what is possible.
