probably for both headphone amp and as line drivers.
Maybe 2 pair for a balanced feed around the house (CAT5).

Default Will there be a second round?

If so, I'm interested in two boards. If not, well, too bad for me!

These are very nice. I was the lucky recipient of a pair thanks to the kindness of a fellow DIY'er. I would vote for a second round. I use mine every day.

Well, if interest is high enough I will arrange a second round.

I built up my amps. I zero'd the offset with the pot at the min. Trouble is, my dcoffset is varying with volume.

Any ideas?

sounds like the volume pot is acting like a variable resistor on the front end of the power amp.
The input needs a DC block if the volume pot is not buffered to near zero ohm source impedance.
