I'm upgrading from an integrated amp to a pre/power combo, with a separate AV processor, so I will end up with: processor -> power amp (for rear and centre channels) and processor ->pre-amp -> power amp for front channels of 5.1 I need to route the processor (Yammy E800) via the pre-amp since all my audio sources are connected to the pre-amp and I am using a single 5-channel power amp. Question: Do I need the total length of interconnect between processor and power amp (whether direct or via pre-amp) to be the same for all channels? Ie: processor ->2m-> power amp mixed with processor ->1m-> pre amp + pre-amp ->1m-> power amp Would it matter if the direct channels were shorter than those routed via the pre? For example: processor ->1m-> power amp mixed with processor ->1m-> pre amp + pre-amp ->1m-> power amp ? If I could get away with connecting like this, it will save me a little money since I only need to buy 5x1m interconnects to add to what I have already! Any advice greatly appreciated.
