pimp portable amp

There have been cmoy's, a47's, modified linkwitz crossfeeds, meta42's and now the pimp portable ppa headphone amplifier. The ppa features a modified linkwitz crossfeed, bass boost (still in need of tuning), AD8610 op amps (socketed with Burr Brown opa627 and opa637 in the listening queue), 12 buffers, a battery board housing 12AAA NiMH batteries and a recharge circuit, a toaster and the kitchen sink.
