Vinyl vs. digital: what am I doing wrong?

I'd like to ask you all for help with my TT setup. I think I've amassed what should be a nice sounding TT setup. However, I don't think that vinyl sounds as good as my CD (e.g., comparing the same album on vinyl vs CD).

What am I doing wrong?

Here's my TT setup:
- Basis 1400 with clamp
- Upgraded power supply
- Rega RB300 tonearm with Incongnito wiring
- Shelter 501MK2
- VPI 16.5 cleaner with AudioIntelligent cleaning products
- Zerodust stylus cleaner
- TT set up by Brooks Berdan

CD player:
- Metronome CD2V Signature

Rest of system:
- Martin Logan SL3
- Cary 805 amp
- Music Reference Amp
- Supratek Chenin preamp with built in MC phono stage

Thanks in advance for your help.
