Surround Speaker cabling question

"For left and right front channels, using excellent quality cabling, would you hear a difference between 1.5m for one side and 5m for the other?"

My opinion is 'no'. I'm running 4- and 9-foot lengths of premium cables to my L/R speakers. The one clear result of matching lengths is bad--the speaker with the longer-than-necessary cable has looser bass because it's seeing a much lower damping factor.

theres one more point. the pres. abilety to dr. the cabels length.

I ended up getting harmonic tech's pro9+ in these lenghts 12 foot(fronts), 11 foot(center),32 feet(surround left) and 43 foot(surround right)
thanks for all you comments,
Mike
