Go to Frank Harvey on Spon Street. Book yourself an appointment and you can listen to some music that you know well, on whatever kit you're thinking of buying. Tell them a price range & they'll sort you out. It's where I got my turntable - great service, I'd definitely go back. Reviews are all very well as a starting point, but they're your ears. When you start comparing stuff you can hear a massive difference. You can decide whether this or that upgrade is worth the money, based on what you hear.
