That's what you get for using cheapo TT + cartridge and drop-in 50 bucks soundcard .
I wouldn't just assume that it sounds bad because the equipment is bad. I have a 24-bit rip of LCD Soundsystem's "Sound of Silver" ripped with:
RCM: Nitty Gritty Record Master I
Table: VPI HW-19 MKIII with corian plinth on sorbathane pucks
Tonearm: Rega RB-250 w/ cardas rewire
Cartridge: Ortofon Kontrapunkt A w/Soundsmith Ruby Cantilever Re-tip
Pre-Amp: Pro-Ject Tube Box II w/ 2x12AX7 Telefunken Ribbed Plate Tubes
Cables: Custom – Canare quad core cabling with neutrix RCA ends
Interface: Creative Sound Blaster X-Fi HD Sound Card – USB
Computer: MacBook Pro 2.2 GHz Intel Core i7; Mac OS 10.8.2Software: Amadeus Pro / MusicBrainz Picard
The surface noise is pretty meh.
