Advice on new cables


Hello, everyone
I am looking for your recommendations on speaker cables and IC's for the following system:

1. Accuphase dp67 cd player;
2. Audio Research Reference 3 preamp;
3. Onkyo M510 Grand Integra power amp;
4. Proac Response 4 speakers.

Currently using MIT for all cables. The music I listen to is mixed: jazz, classical, rock, blues. I can't detect anything wrong with the current cabling, except that my concern is that the current cables are limiting the potential of my components.
Thanks!

What model MIT are you using? Your question is a little vague - there are many variants in the line...
My current MIT cables are the following: Shotgun AC1 power cables; Shotgun S3 balanced interconnects; and Shotgun S3 speaker cables.
Why would you think that your cables are limitation?? I think your speakers and amp are suspicious.
