Confused - what to buy DAC or CD player?

Folks,

I need people's opinions in figuring out my next component - CD player or DAC. Unfortunately, I won't be able to demo the cd players and DACs at one time to do head to head comparisons - so I'm requesting your input.

My current system:

Speakers: Soliloquy 5.0s
AMP: Sim Audio i-5080
Currently using a Toshiba SD 3109 DVD player for a source (but I don't like it).

I'm willing to spend up to $700.

The options I am considering are:
1) Rega Planet 2000 - around 650 used
2) Bel Canto DAC 1.1 - around 650 used
3) Channel Island VDA DAC and VAC P.S - 500 new

The music I listen to includes rock, electronic, classical, r&b, etc.

Please let me know if there are other cd players/DACs that I should consider and/or what you think my best option is and why.

Your help is appreciated.

Thanks
