This is a group buy for the acclaimed Bottlehead Crack Headphone Amplifier kit. This is widely considered to be one of the best OTL Headphone amps available under $500 and is often compared to amps priced above the $1000 mark. "The Bottlehead Crack is a superb introduction into the world of DIY audio. The parts quality is very good, the documentation is truly excellent, the Bottlehead forums provide fantastic peer-to-peer assistance, and construction is very easy. The Bottlehead Crack is an outstanding first project for the novice audio DIYer. The big win, however, is that once you've finished your build, you'll have a fantastic sounding amp for your high impedance headphones. I simply can't recommend the Bottlehead Crack highly enough, if you've got a yen to try a little soldering, this isthe way to go. You'll love it!" - Tyll Hertsens, innerfidelity
The initial goal was to come up with an easy to build, great sounding design that would harken back to Bottlehead's early days. Crack is our version of classic OTL headphone amp designs of several years ago that were hailed as some of the best sounding of their day. This is what we call a Skill Level 1 kit, perfect for first time builders. The circuit is so simple you can build it in an evening or two. A simple circuit also means a low parts count, which keeps the price low, too. Crack is an output transformerless amp designed specifically for running higher impedance (200 ohms or higher) headphones like the many Sennheiser, AKG and Beyer designs.
