Are there any brands that you’ve tested that I should look at since you guys only have 1M?That will be fine, the longer the length of the DC cable the more of it’s “sonic signature” it may impart and longer or shorter runs of the same cable may even sound somewhat different, but technically there is no problem with using different lengths. And you can choose a different filter combination to compensate…
I assume the $5 one from Amazon isn’t the preferred choice…but curious to know your thoughts. The larger cable manufacturers that I checked didn’t seem to carry these.
