I'm building my first amp for my Grado SR-80s. Needless to say, I'm rather excited.

I've decided on the parts below after reading through Tangent's and Moy's tutorials. I'm going to build a wooden housing to put it all in when I finish the circuit board. I'm going to be using a radioshack protoboard, the following parts are from digi-key. Tell me what you think of my selections:

How much of an improvement over my current home cdps (in my sig) do you think this will give me? Lightyears ahead, or just a bit? Lastly, if you have any tips on building/tuning let me know, I'll need them.

Sorry to be impatient, but I hope to order this tonight, and the excitement is getting to me.

You should enjoy it a lot.

I have a feeling I'll be posting about a maxed out meta42 in a month or two...

For a first time builder I would recommend the OPA2132PA dual opamp...less wiring headaches.
I would also go with a TLE2426 for the PSU rail splitter (normally I advise you to go with a BUF634 but that can complicate things).
One item I noticed missing from your parts list was a battery connector, so I'm left guessing you already have that covered?

Good luck building this puppy.
Don't forget the amp Pr0n when its finished.
