I am considering building a headphone amp and have narrowed it down to either a Pimeta or a PPA. I will buy either board from Tangent's site along with some of the harder to find parts and most of the rest from DigiKey and/or Newark. The following are some points that I would be interested in hearing anyone's opinion on:
1. Cost - I realize that there is almost an infinite array of optional parts and configurations for both designs. For a start I will stick to the basic equipment (no crossfeed, diamond buffers, etc). I don't plan on buying any really high end components like Black Gates (most likely Panasonic FC caps, etc). I guess what I'm asking is what would it cost to build a PPA vs. a Pimeta?
2. Complexity - Neither design is as simple as say a CMOY. To me the PPA has more parts than a Pimeta but shouldn't be any harder to assemble (just more of the same). I would imagine that troubleshooting a PPA would be harder than for a Pimeta. It seems the most complex part of the whole thing is choosing and finding components.
3. Sound - I would like to tackle a PPA if items 1 and 2 are not a major issue. Currently I own a self modded MF XcanV2 amp. How would either of these designs compare to it? (OK here we go, talk about a subjective question
