I had the same problem as you. My HiFi system is 26ft away from my PC. What I do is record all my LPs on to cassette. I then use my portable cassette player (which is permanently connected to my PC) to transfer them to CD.
I use LPRecorder from click here
to record it as one long .wav file and then use LPRipper (from the same company) to split it back to separate tracks.
You could also use JetAudio (which is a free download) to record them to your hard drive, although each track has to be recorded separately.
