50 foot cables?

However, I would do everything possible to knock down the length of those speaker cables. Even 25 feet long is crazy and IMO probably will have some negative sonic effect.

@ tuberist,

"Even 25 feet long is crazy and IMO probably will have some negative sonic effect."
I have been using 25 foot long speaker cables since 1992.  Let me assure you their is no sound degradation.  I spoke with McIntosh the manufacturer of my amp and was told there will be no sonic degradation of sound.  I checked with my speaker manufacturer(s) and Sandy Gross from GE told me there is no sonic degradation of sound, lastly I have a EE degree and know there is no sonic degradation of sound. 

My speaker cables are 11 gauge and 25 feet is nothing for a 300wpc solid state amp.  I wonder where everyone gets their information from?  For fun, I moved my speakers next to my amp and tried 5 foot cables and trust me, there was no difference between them and the 25 foot pair of the same cable.   If there was, do you think I would have 50K of equipment in my listening room if the cables degraded the sound?

Thanks, and if it turns out he only needs 25 feet just coil the rest and pile it in with the rest behind the rack. It can't make any difference. stereo5 said so, and he has 50K of equipment. 

@millercarbon,

learn how to read, I know it is hard but you can do it.  Please show me where I said to coil the rest of the wire.  I’m waiting..................
