Now through July 4th you can show your independence by ordering a made-in-America headphone amp kit that you build yourself.
Bottlehead will be transitioning to a universal power transformer in the upcoming Crack 1.1, but still has a quantity of 120VAC only Crack kits to offer before that happens. The Crack alone is normally $299, now at a special $249 price.
Further sweeten the deal you can add a Speedball upgrade kit (regularly $115) to your order for just $50. If you do the math that works out to ordering a Crack and getting the $115 Speedball kit add-on for free!
Shipping adds $15+ UPS most places.
This is one of the best OTL (amplifiers available for high impedance headphones (>250 ohms).
Perfect for those who bought the Sennheiser HD600 and HD650 in recent deals.
This is a DIY kit and requires assembly and basic soldering.
