Perfectly good wire especially if all is quiet and it sounds good. That cap is just fine.

Sure, CAT5 works well. I personally like the Cat5 with PTFE dielectric, you can often find surplus of it on places like ApexJr or ebay

I strongly like it!

What headphone loads can this amp handle?...the one shown for test seems to be 16 Ohms

Anything except a pure electrostatic. (which would require a specialized amplifier)

Stax electrostats with the transformer are fine.

One of the design goals was to be able to effortlessly drive any headphone -- which it does with style, ease, and grace.

Anyone tried a Burr-Brown OPA2134PA rather than the LM833?

I am also interested in this project.
The FQP is much cheaper than IRF. Don't know how to make a decision. Is there any audible between them? Or which one work more stable?

just buy what's easier

difference , if any , can be just marginal and strictly in taste department
