[QUOTE="HCCA, post: 3994931, member: 571196"] The problem is NOT the output voltage. The problem is the distortion that ALL head units without switching power supplies have. Just in case you weren't aware, it's like having the gains on your amps up a 1/4 turn past where distortion sets in. However, there is NO adjustment on HU's to eliminate this problem. Sure, I could just measure where the distortion begins, make a note of it, and not turn it up to that level.....And, I could just duct tape my speaker wires to the surface of the carpet too! LOL... No, I would like the peace of mind to know that distortion CANNOT get into the system from the head unit. Level matching to the amps CANNOT stop the inherent distortion that is present in the last 10-20% of the volume control. Now, the H701 HAS a switching power supply.
