I just checked out the Bottlehead website and saw they’re having a special promotion where you get a free Speedball upgrade kit when you purchase a Crack kit ($279). It’s only for the first 25 orders and I don’t know how fast they sell their stuff but if you are looking for a great tube amp that is fairly simple to put together, you should check it out. http://www.bottlehead.com/store.php?crn=224&rn=442&action=show_detail. I put together my first Crack a few years ago and got the Speedball upgrade recently. I love it for my Sennheiser HD 650s and Beyerdynamic DT 880 Premiums. The Speedball upgrade is definitely noticeable and also helps keep the unit cooler. Anyways, thought I’d share this as it’s a fun kit to build and very popular among Head-fiers.
