Bottlehead Crack Wspeedball
Writing a review after isn’t easy, so don’t shoot me if this review turns out short 😉 The Bottlehead Crack amplifiers arrived a little over two months after having ordered them on Bottlehead’s website. We ordered a couple of Cracks right before the price increase was announced (more on that later) so that probably explains the long waiting period. As Mike mentioned before in his Facebook notes, it wasn’t always easy communicating with Bottlehead, with emails getting lost/unanswered but a couple of phone calls and lots of emails later we got our DIY packages in the mail. Bottlehead did forget to send us the logo badges we paid for and the wood of one of the casings was slightly damaged but we were to excited to complain about that and we decided to build them like that.
The DIY Crack is a fairly easy to build amplifier, anyone having experience with soldering and a multimeter can surely build one himself. Bottlehead also includes a very detailed step-by-step manual making it almost impossible to screw up.

If you don’t feel like building the amplifier yourself, you can always order a pre-assembled Crack from Bottlehead, at an extra cost of course. Anyway since Mike did the build on both our Cracks, I will let him talk more about the building process later. Like with every Bottlehead design all in- and outputs are located on top of the amplifier (even the power cable goes in on top). That can be unhandy when you don’t have a lot of space or when your interconnects and power cable are rather unflexible. It doesn’t really bother me but I’ve seen a lot of people using L shaped plugs with the Bottlehead designs and other DIY’ers have changed the layout and put the connectors on the back and front.
It’s a DIY project so if you have the skills you can do pretty much whatever you want. Some people like the look of the Crack and others hate it. Parent taught driver education ptde in texas. While I think its looks are basic and very cool, I have to admit that having all the cables on top will probably never make it win a beauty contest. Looks do matter when buying an amplifier but in the end the sound it produces is more important, and that’s where the Crack really shines.
I’ve only been using my beloved Sennheiser HD650 with the Bottlehead amp. I specifically bought the Crack for this headphone after seeing raving posts about this combination over and over. Most of my other headphones have low impedance or are orthodynamic headphones and the Crack wasn’t developed with those in mind. I did try it briefly with the Hifiman HE-400 and while that worked, I didn’t really experience any distortion like Mike, it doesn’t really need the Crack and it also doesn’t do anything special to it. (only normal with the HE-400 not really needing any amping).
I was very happy to notice the Crack was dead quiet with the stock tubes and with my replacement tubes (it doesn’t hum at all). The volume button, being a bit bulky, is smooth to turn and I never needed to turn it further as 10 o’ clock to get to my preferred listening level, so there is more than enough power left for you to play with. Even without any music playing, turning the volume pot was completely noiseless. I rather quickly replaced the stock Electro Harmonix input tube with one of my RCA clear top tubes. The stock configuration is good but the RCA tube just gives the amplifier a bit more body and weightier bass. Overall the Crack is a very clean sounding amplifier picking up every detail the music has. Bass is deep, well defined and punchy, the mids are very natural and smooth and the treble is nice and sparkling. Nokia n8 pro edition v5.
