Bottlehead provides excellent instructions as a PDF on a disk that take you through the process step-by-step with good visuals and a consistent and understandable number scheme. You must build the Bottlehead Crack - it is only available as a DIY project (with the exception of Ebay). It is a notoriously good pairing with Sennheiser's higher-end headphones, most notably the HD 650 and HD 800. Because of this, it is best paired with headphones with high impedance (technically higher than ~120ohms, but most recommend over 300ohms). This makes the Crack output transformerless (OTL) and thus it has a high output impedance. The Crack is a relatively inexpensive pure tube amplifier, as it does not have an output transformer. It has no solid state in the signal amplification path. The Bottlehead Crack is a pure tube amplifier created and sold by Bottlehead Corporation. I will offer my impressions of the speedball upgrade kid, upgraded potentiometer, upgraded tubes (both input and power tubes), and other miscellaneous upgrades. This review will include impressions with the Sennheiser HD 650. This review includes information about the Bottlehead Crack amplifier.

I just noticed a 'reviews' section and figured I would write what I know about the two amplifiers I own, the Bottlehead Crack and the JDS Labs Objective2.
