Hello, Yes I see your point, perhaps this should have been made at the start! I do understand about Audiophiles and there quest for purity, one can look at many arguments on sound reproduction all the way back to which type of thorn tree is best used for the pickup on the horn arm (The list goes on, all the way to the present day of digital VS analogue) I do think that you have asked a question that is beyond the rellms of the PICLIST. PS I still have may 6 x 1KW valve amps at home, currently connected to a cheepish KEF reproduction system. Dennis
