Made with Cardas Eutectic Solder, the best solder there is

Speak to me about upgrades!
-----------------------------------------------------------------------------
Cardas quad eutectic solder is used for all my kits. This solder is top of the line and contains silver for higher conductivity. With this type of solder you will not have to worry about cracked joints later in the amp's use. It is built to last.

A great amount of detail was put into this Bottlehead Crack headphone amplifier. The chassis, transformer, and screws were painted with metallic paint. The wooden base was sanded and stained. It was then finished by hand with special oil with increasing grits of sandpaper between coats to get an ultra smooth finish.

The wiring for this amp was done neatly to provide a pleasing appearance. Each terminal was carefully inspected to ensure that all joints were properly soldered. The resistances and voltages were then tested and passed all tests. Finally, I've listened to the amp with my own set up to ensure it was in proper working order.

The Bottlehead Crack is an exceptional headphone amp that pairs well with high impedance headphones such as the Sennheiser HD 650's and the HD 800's. The music really shines with live or acoustic music.

If you have any questions or concerns, please do not hesitate to contact me.

*The amp has a universal transformer. Let me know if you need a voltage other than 120V (US) and I can modify this for you free of charge.

Im not much of a reviewer but i will say James exceeded my expectations. I was hesitant at first but then I decided to give a shot. The amp came carefully packaged. The amp sounds super great and I kinda wasn’t expecting it to sound superb for my hd600s. It literally sounds like hd800s. You won’t go wrong with James. He will answer every question and will send you updates on your amp. Everything just came out perfect.

Absolutely perfect in every way. It was built exactly the way it was shown in the pictures and what was amazing was the communication. There were constant updates on the progress with photos. I would highly recommend buying the amp through this amazing builder because not only you don't have to solder all the internals yourself, you don't even have to worry about how to make the chassis look clean and presentable with professional wood coating.

James did an amazing job with my Bottlehead Crack! His attention to detail is impressive. The paint job and wire management are perfect. The constant communication and progress pictures during the build were greatly appreciated. He made sure to give me some very helpful tips before the unit arrived. James does not mess around with packaging either. The amp was covered in protective paper and masking tape, surrounded by a few layers of bubble wrap, placed on top of foam, and surrounded by packing peanuts. The best part, James made sure to fold the ends of the tape to make little handles to pull on (talk about attention to detail lol). This amp powers my HD6XXs beautifully. I’m very impressed with the pairing. If you have a pair of HD6X0s and no time to build a Bottlehead Crack, James is your man!
