Hello, How long have you had the PL5? All the reviews that I've read love both the PL6 & 7. One review said that they liked the warmth of the midrange in the 6 with the EL34's, but that the 7 had a tad better range in the upper and lower ranges. I guess it may depend on the types of music that you listen to most often. What TT/ cartridge are you using currently? Thanks for your input, Steve
