Cleaning out my basement the other day, I found 2 PPAs I was assembling some time ago. If you don't know what a PPA is, it is a DIY headphone amp that was state-of-the-art several years ago. I seem to remember that they were designed by Morsel, Tangent, and Phil Rocco. I've not been on Head-Fi in so long I don't even know if they are still around in the forum.
In any case, they are 95% assembled and both work. They need the case work done on them, which includes installing the headphone jack and the audio input plugs. They have boutique nichicon muse caps, with some diamond buffers, pots to do the bias trimming, the whole nine yards. I remember being so excited about these, and then my wife got pregnant and things changed. I still listen to my HD600s, but through a home reciever rather than needing a separate amp.
I'd like to sell these mostly assembled PPAs to someone who would want them, but I don't know if they are worth anything since it has been so long. I think I put something like $100 in parts into each PPA (I have the parts receipt around somewhere), and I'd be willing to get rid of them at a discount, but just don't know how to go about it.
I know this is a strange request, but can anyone comment and let me know if they're worth me trying to sell as-is?
What would YOU do with them?
