…”Equal length cables are always recommended, I’ve played with un-equal length and never been able to hear the difference. ”
I have to agree. While I did not do this when I was tremendously experienced with high end audio. In the end, I always have purchased equal length cables. If you are an audiophile, then go for equal lengths. I doubt I could stand realizing I had vastly different lengths. An audiophile system is the result of having no small compromises, they add up. But if you are just looking for good sound, then get different lengths.
Hide the extra cable behind the rack… or under the rack. This is what I always do.
