got a 50s record player from my gfs dad and quickly built up a stack of classic lps! i love it, but im thinking newer ones would sound much better..? so...what do i need? good turntable, amp and speakers? ive seen usb turntables, but perhaps ignorantly, i think that cheapens the whole thing? can anyone recommend some hardware for me? also..will modern ones play 7" singles and lps too?
