has anyone compared Cat JL 1 to Cat JL2


a direct comparison,
eralff
I never did compare the two but I purchased another 125lb monoblock instead. After purchasing the atma-sphere I haven't looked back....YET. Well maybe a few times.
My JL-2 arrived last week and is fantastic, but I never heard the JL-1. I understand the JL-2 has a teflon circuit board which makes a sound difference over the JL-1. I don't understand why.
Suttlaw, what amplifier did you have before? What are the improvements brought by the JL2?
