Up till last night, I was confident that I was going to construct an M3 for my headphones. However, I stumbled upon Dr. Meier's post in the Members of the Trade forum regarding some HA-1 MKII boards. Seeing the limited quantities, I ordered one. Now, I am stuck. Both amps have been getting good reviews. Since I am getting the HA-1 board, I will build it eventually, whether or not I build the M3. I need to decide which one to build first. Which one would be a better match for the K340's?
