newbie DAC question


Hello!

I broke into the HiFi world about two years ago and l would love to know if a DAC would improve my system in a way that's worth my while. I currently have the following setup:

- Elac Debut B6s
- Music Hall A15.2 integrated
- Onkyo C7030 CD player
- Sextet and Bel interconnnects borrowed from a buddy
- Speakers are on stands carefully placed where they work best with the carpeted room.

I've read good reviews on the Musical Fidelity V90DAC and several Schiit models, but I can't determine, based on any literature out there, if my setup is at a level that would make a DAC worthwhile (or even noticeable). If it WOULD make a difference, does anyone have any suggestions for coaxial or optical interconnnects to go along with it?

Thank you much!

Multibit is said to be "Bit Perfect" for the conversion of PCM (Redbook dc) many hiend manufactures are reverting back to it for PCM replay, after going down the cheaper Delta Sigma conversion way, like Schitt did for this Bifrost which is Delta Sigma, and now the upgrade for it is back to Multibit dac.

Your Onkyo btw is a Delta Sigma based dac converter. It will be interesting to see what you think the sound difference is playing Redbook cd using it as a transport into the Schitt Multibit dac.

Myself, the sound of Redbook when converted with a properly implemented Multibit dac has a dynamic  jump factor and a body to the midrange that Delta Sigma can’t match, it’s sweet and laid back but a bit of a yawn to listen to after a while, and doesn’t excite and keep your attention like Multibit can on rock, middle of the road, or classical.

@georgelofi fantastic description, thank you for taking the time to explain. I'm leaning towards a B-stock Bifrost multibit now :)
@kremrik - Blue Jeans is a solid choice. You won't go wrong there.

And yes, I think a DAC connected to your CD player would make a noticeable difference in your system.
@yage thanks for the recommendation! I just bought a coax from Blue Jeans and an open box Musical Fidelity V90Dac so we'll see if I can see an improvement
So I bought a Blue Jeans Cable Belden 1694A Coax, RCA terminated at both ends. I've heard some people say that coax is inferior to optical. Thoughts? Or is it one of those things that's endlessly debated with no concrete conclusion?
