What is beyond the Cosmic Microwave Background?

So I read that the Cosmic microwave background is the ultimate thing what we can see using the most powerful telescopes. It is still possible for us to build a telescope to see even farther ?

We can't see past the CMB because earlier than that, the universe was opaque to light. We could see further back if we could detect primordial neutrinos, which pass freely through plasma. That would allow us to see back to something like a few minutes after the big bang. Gravitational wave telescopes that don't yet exist might also allow us to see farther back.
