I would really like to build a solid state headphone amp first. I actually worked on receivers with tubes in the Navy & was awed when solid state came out. lol. I know I am in the wrong section, but it sounds like you have built a lot of audio equipment and could give a few pointers. What would you recommend? I have Grado's & Dennon for headphones.
Thanks,
Teresa
p.s. I build computers, networking systems, program software.
Wondering if programming dsp has been explored for diy? I do a mean fft
