There are real improvements with thicker and different cable designs. Whether these improvements are significant enough depends on your hearing ability.
The trick I have often used is to raise my existing speaker cables in the middle with a high back chair (you need at least 3 feet for this test). This forces the electrons to go uphill and over a big bump in order to reach the speaker.
If you can hear the difference caused by this effect then it is probably worth upgrading your cables. Myself, I have such poor hearing that it is not worth the extra money.
