What Can You Do With A Thorens?

I have a Thorens TD145 that I bought at a second hand shop in seemingly perfect running condition. The phono cables were changed out by the store proprietor, nothing fancy. I bought the Thorens because after buying high end speakers, a high end DAC, a very nice phono stage and an extremely nice amplifier (not to mention cables) I then began to run out of money. The dilemma; could I live with a nice collection of mostly classical late 1940's to late 1950's mono LP's with nothing to play them on? Now along comes an audio friend from the hippie days and I tell him that I am planning to purchase an Ortofon Cadenza mono cartridge for my Thorens TD145 and he says, 'what about replacing the wire that runs from the phono cable to the tone arm wire with pure silver'? Yes, ...well I've never even considered it and why?

At this point I've decided on the Ortofon Cadenza Mono cartridge, a JA Michell record clamp, a 'Spin Clean' record washer but then what's to come later on when I get the urge to push this little old Thorens to its audiophile limits? Should I be so crazy as to a change out the tone arm, or solder those microcosmic angel hair pure silver braided wires from the tone arm wire to the phono cable or should I replace the generic thin grey phono cables with expensive high end magically shielded phono cable?

Can I possibly separate audiophile myths from worthy turntable upgrades; 'Out with the old stock and in with the new'?
Happy New Year by the way.
