Sapphire 3, assembled 1 pair rev 3.1 boards with the contacts for the 2540 discrete op amp modules as well as regular DIP8 socket. Boards are set up as a headphone amp, standard BOM, switchable 15/25 dB gain.
With the 995 FET module these sounds as good as the Sapphire 4 ... though less cost effective, I admit: there's over $100 in parts per board, as the 995 FET alone sell for $69. Multicap PPFXS coupling caps.
Price is negotiable, I can remove the modules and caps if you want. I can also sell the 995 FET modules separately, that's not a problem.
