I am interested in some advice. I am still in the process of obtaining equipment for my 5.1 setup. I have the marantz 7005 av processor and the sdc250 amp (2 ch) from class d audio, and my speakers Chanes tower and center and rears infinity. My need is this interconnects and power cords. I have researched for a few weeks on both. I decided on buying 3 pair of OCC silver plated copper cords with gold rca plugs (from enjoyhifi on ebay) with this in the description---Occ Copper, --- 3 core .2mm--- 2core .3mm---1core .4mm---1core .5mm with signal diameter of 1.5mm, 7N silver plated, and teflon insulated. (3pair $65). The power cords (also from enjoyhifi on ebay) were these---8Ag plated OCC power cord--- 16 strands----1.5mm per strand----diameter 11mm, High Purity OCC copper with silverplate and rhodium plated plugs. I got 1.5meter and a 2 meter one. Well ok so far. I had them since september 8 and today is the final day I can send them back (if I want to). Anybody familiar with this type of silver plated copper wire? How is the performance on your equipment? I have burnt them all in for the last 3 weeks at 16 hour days. I have done tests with my old supplied regular power cords (Marantz and Class d Audio ones) and found a slight say 10% better audio experience. The very cheap old interconnects were improved about 15%..... did I do well here? Should I just get less expensive OCC shielded cords? I am impressed with THIS-------the old generic provided power cords provided by both Marantz and Class d audio both fell in performance for the initial 30 minutes in my A to B testing BUT the performance caught up to the new silver power cords AFTER 30 minutes of use to 95% of performance with using the new silver power cords. I probably should just send back the power cords and keep the standard provided ones and just keep the new silver interconnects.....WHAT DO YOU THINK?
