Temper W is a mid compliance MC cartridge, FR-64S is for high mass cartridge, such as Koetsu, some Ortofon model, SPU series, Kiseki, FR own model, it will sound dull and boring with the Temper W........
I will opt for option no.3, for phono amp, you can get a new Trichord Research DIABLO from Amazon UK or some online shop, if budget is tight, DINO Mk2 is a nice choice under 10k. You easily find the UK dealer on eBay UK. Another budget choice is Sutherland Ph3D or 20/20, there should be another model under 15k price point, you can ask the HK dealer.
