Bottlehead Crack Headphone Amp just completed July 2016, with Speedball upgrade. I use a Crack w/Speedball and aftermarket tubes (Sylvania) with my HD650s and find it extremely enjoyable and non-fatiguing. Bottlehead Crack With Speedball For Sale.While I normally would have turned to to shape me up a new chassis, it was time for me to step up and build my own, despite not being crazy about working with wood. Years later, I reminisced how much fun it was to put together that point-to-point Crack and decided to build a new one from the ground up with fancy parts and give it a layout that would accept that added girth. I shortly after its release and of course replaced a number of the parts with racier versions and it sounded quite good. I also highly recommend the Speedball upgrade, which replaces the plate loads on the tubes with a constant current source and brings this amp into its own with added detail and transparency. The Crack has gone up in price a little bit since its introduction 3+ years ago, but it’s still quite a value. A great little tube headphone amplifier at a price-point nearly anyone can afford that sounds very good for the money, it’s really hard to go wrong here.

I’m going to guess that the Crack is Bottlehead’s all time most popular kit.
