Agreed, very interesting. I would strongly suggest that if you haven't already, the next step would be to invest in Mono cartridge/ stylus. The 'Expert Stylus glider' is great value for money. I would also recommend the Loricraft record cleaning machine as it uses a vacuum to suck the dirty cleaning fluid out of the grooves and leaves the surface of the record entirely dry. One can also 'leave a 45 to soak' whilst not damaging the labels. I bought my unit 20+ years ago and it only just gave up the ghost. To my surprise 'Terry' at Loricraft is still going and I shipped it back for a full service, two weeks later my machine was returned in perfect working order for a very reasonable price indeed. Loricraft also 're-vamp' old Garrard 401 turntables which I use for my 78's (also with an SME arm and cartridge wired for Mono). These turntables are outstanding and can be used for all speeds. I use a Lynn deck (SME arm, Mono cartridge) for my 45's just because I got one cheap so many years ago and have never heard anything better. But, of course, it's all subjective!
