Rotarius,
There have been lots of replies that have been informative and insightful. Please consider all the input available to you in your 'quest'.
Now, this is what I have to offer.
Yes, you should always make sure you configuration is correct. I recently learned the importance of this step. Having moved to my first apartment (yay---freedom, freedom, freedom), I found my stereo to have too much soundstage and the vinyl reproduction to have too lean bass (coming from a VPI hw19 mk iv with a RB-250/Denon 301 combo...something was definately wrong). After checking polarity on my speakers and placing them closer to corners, the sound (to me) was correct and better than ever before. Lesson: you should never skip the slightest step in setting-up your system.
In addition, you should also do some 'burn-in' of any new cables. Try also a setup disc (like the Ayre) to make sure your configuration is correct.
Now, I'm not saying that CD is that great with string music. I'm a vinyl lover with a large CD collection as well. A inexpensive TT with a good Phono-pre and a better amp/speaker combo can blow out a mid-range cd player without difficulty.
My honest opinion is that you should give a good listen to a properly setup vinyl reproduction system. You will have another perspective on how music should sound and what you can do.
Get a MMF series, Thorens, or Rega P2/Goldring 1. Match a Bellari or Nad Phono Preamp and either a Goldring 1006, Grado Blue, or Shure. Download Audiophilia's Cartridge Setup, Enjoy The Music's Free Protractor, and purchase a bubble leveler and you should be good to go.
Thoughts, anyone?
Marty
