Cant go wrong with the polks..Ive had a few Kenwood HU,and JVC,and never enjoyed them..seem to have never lasted for me.Always had fading issues,buttons going out ect.Never had an issue with that sony hu..I currently use Eclipse CD8455,and CD3000,Clarions are not too bad either.Havent had a Pioneer since the early 90s when they were Supertuners,and looking at the PRS80s
