For Sale or Trade:
FS/FT: finished Bottlehead Crack for kit Crack or others (Canada) (sold)
Will Trade For: Crack+Speedball, maybe others
Will Ship To: Anywhere
So I've got the DIY bug going strong and I feel like building another Bottlehead Crack. I am offering my current Crack+Speedball in working order for a new kit from Bottlehead (either one you already have or you can order one and have it shipped to me). My kit came from one of their earlier runs which had different (and reportedly better) tubes. I built it this past summer and it has accrued maybe 20-30 hours since then. The Speedball upgrade was obtained a few weeks ago and only a couple hours have been put on since then.
I'm no professional, but everything is functional and I'd gladly provide more pics if requested. I recently retouched most of the solder joints as well to ensure good connection. Everything is stock; I have made no mods to the Crack. The chassis plate was hand polished to give a nicer sheen (though there are some tiny scuffs I wasn't able to remove), and the wood base has a simple finish to it.
The amp is not dead silent; I can detect an extremely faint hum when the house is quiet and listen very closely, but it is not noticeable at all when music is playing. From what I understand, this is not uncommon with the amp (I recently built a Bottlehead S.E.X. amp and it has the same barely-there hum). It meshes beautifully with Sennheisers and Beyers (and I don't even like Beyers to begin with), and my absolute favourite combination is with my AKG K240 Sextett (MP). Please note that the Crack is not designed for low impedance phones or iems (anything under 120 ohms). In my experience, it pairs best with Sennheisers and vintage AKGs, okay with Denons and Grados, and badly with Sonys. You can ask me for specifics if you like.
In milosz' big A/B amp comparison thread, the Crack+Speedball is his favourite amp for his Sennheiser HD800, which is quite high praise indeed considering the competition. (link)
I am open to other trades (heck, I might even be convinced to part with my MP Sextetts). Mostly interested in other kits, though open to anything really. If you have any interesting offers, give me a shout.
edit: also interested in a MAD Ear+ kit or Elekit TU882R kit
Willing to ship outside of Canada/US, but we would have to work out shipping arrangements.
