Hi there; AR pots and L-pads used in an AR-2 speaker system? I am choosing the, AR-2, as an example only, I am certain this was not the only model affected by this topic. I am writing this because, with all of the write-ups I have seen, I find it overwelming, I cannot read between the lines, as to which is or not correct to use. I have read, that some listeners do not like the sound with the L-pads. Why not? What does a pot do, that an L-pad doesn't? What does an L-pad do, that a pot doesn't? T
