It's been done for a while, but here's my Pimeta. Many thanks to Tangent, Nate, Garbz, Pars, and the rest of you fine folk who share your knowledge here every day.

Upgraded PIMETA buffers (Discrete Diamond buffers from PPAv2) on left and right channels. I didn't have enough room to fit the third board intended for the ground channel. I would like to thank Tangent again for both the PPAv2 schematic and his assistance in helping me shrink the board size.

The 10000000$ question: How does it sound compared to the buf 634?

I find it to be clearer and more detailed. The difference isn't as dramatic as, say, an opamp swap, but it's there. The clarity is more prevalent in the midrange and highs.

*EDIT* While I'm at it, upgraded case with improved ventilation (3 vent holes per side towards back) and completely clear 3/32in thick acrylic. This time, I owe a HUGE thanks to my dad for helping me with the acrylic.

Check Digikey.com, Mouser.com, or Newark.com for this case. I'm not sure, but I think it's a Serpac case.

Wait... Hammond, not Serpac, my bad.
