Hi Sam
We really must get together soon, my vinyl replay equipment has taken several fairly giant leeps forward over the last 12 months since I bought the Garrard Turntable and 12" Sme arm, I really think you will like it. (I guess i owe you for several albums too

) Also the Glasshouse 300b amplifier is an excellant peice of equipment I think you will enjoy.

Nice to meet you Sunday, sorry it had to be so brief, maybe next time we can make some time to play some music.
The Thorens is an excellent turntable and will sit happily in most people system without the need to ever upgrade IMHO. As I suggested to you, the weak link is undoubtably the arm and cartridge.
The cartridge is old and would benefit from a replacement, however as far as I could detect it sounded acceptable and although I have shit eyes these days, but through a modest magnifying glass I could not detect any stylus tip damage, so no wories about using it in the short term.
If you can find a replacement stylus for the Shure it would be worth obtaining. (Do not throw the cartridge out, its probably still worth £15 to £25 on ebay

) otherwise any modestly priced modern MM stylus will be worth investing in.
As regards the arm, The TP16 arm whilst appearing to be a cheap and cheerful thing it is actually much better than it looks, and again will have a value if you wanted to replace it. It was my intention to fit it with an SME 3009 which would be very "in keeping" with the look of the table, and sounds quite good. You could maybe even consider a more modern arm such as an RB250/300. Not sure about the geometry but I am sure someone across on Vinyl engine or Analogue Department will help you out with that.
Hope that helps
Andy
