i hope you guys are able to do this; for the fun of it at least. and i have a suggestion as to a way to have a proper reference. i would love to be there, but Munich in May is not an option for me.
find some Lps with corresponding RTR 15ips master dubs which are the source of the Lps. then you have a reference which can reduce the degree of personal preference involved in the ranking. or, at least, have that be part of the process to sort out the 'truth' from the 'beauty'.
i've done this exercise a few times using the master tape as a reference and it causes one to have a slightly different viewpoint on the music.....as the tape has essentially no characteristic as a cartridge tends to have. we become enamored with an aspect of the cartridge 'sound' and the tape tends to expose that as 'coloration'.
my expectation would be the Lyra Olympos SL as the overall winner.....and closest to the RTR master tape.
