Check out Sijosae’s DIY Gallery for the largest collection of headphone amps I have ever seen.
“If you’re a fan of creative electronics and mint tins and other cans used as project boxes, you’ve gotta take a gander at this Korean fella’s gallery of headphone amps and other DIY projects. Really cool and creative stuff. Builders will especially want to check out some of his neat and tiddy freeform circuits and some of his homemade tools and diagnostic and helper circuits. Here’s one more nifty pic from the site, a set of speakers housed in water jugs.”
