Are you really selling it 1k?

It does cost an average of 800 ringgit a board to build. The PPAv2 is certainly a very high end amplifier, sports a discreet buffer, separate supply rails, multiloop feedback, FET input and noise reduction, class A transistor output and adjustable bias. Comparing it to amps out there, a good equivalent is a Headroom Max in terms of topology, and the Max goes for 4k ringgit.

Maybe i'll sell it for 1.2 depending on my needs. Add 200 for a case and casework with nice jacks, add 60 for silver wire and 400 for a STEPS PSU. If you wanna go balanced it should be 400 for casework, 100 for Switchcraft XLR jacks, 800 for 2 seperate PSUs and 120 for a PEM Filter. That's about 3.4k for a balanced setup. But technically you'd have the ultimate headphone amp, even better than a PRII which goes for 1600 Ringgit unbalanced.
