Building the headphone amp was a merry-go-round business with ordering lots of components from different suppliers, even running to Jalan Pasar and buying op-amps and getting cheated on the price.
This design is supposed to rival expensive headphone amps, and sounds almost the same as a Benchmark DAC in blind listening tests. For more information visit http://nwavguy.blogspot.com/
