I'm an audio design engineer specializing in the black art of analog circuitry. Standard moving magnet phono cartridges are high impedance devices. That mandates a short cable run from the tone arm to the phono preamp.
A phono preamp is a low noise circuit that boosts the signal and provides the standard RIAA equalization curve and outputs a nominal line level signal suitable to feed into your sound card.
If you're not too picky, and you can find a decent stereo that still has a phono input, you can use the line output. If you're handy enough with a solder iron, the best phono preamp ciruit I know would be a variation of the circuit in
Fig. 3 of
this National Semiconductor application note, AN-346. I would use a different op-amp, change a couple of resistor values in the second stage and add a couple of other components for lower noise and better stability.
If you're really interested, PM, and I'll give you the changes I would make.

Side issue.
NEVER buy Behringer products! They make some good ones, but many of them are rip offs of product designs stolen from other manufacturers, including Mackie, Roland and my old employer, Aphex Systems.
In the early 80's, I designed a number of products as Chief Engineer of Aphex Systems. One of Behringer's first rip offs was one of my designs, the Aphex Aural Exciter Type B. I "signed" my circuit board design with a heart logo. Behringer's idea of "creative" product development was to photocopy the entire circuit board, including my heart logo.
I know Uli Behringer, personally. He's a thief who still owes me over $10,000 from yet another of his skanky maneuvers.
