Not sure. I want the Bottlehead Crack 1.1 Speedball tube amp...
They look very similar. Dark Voice reviews as best for the 600 & 650, a lot like the Crack. Zeos at YouTube does a cool vid on tube rolling using the Dark. Building a Crack sounds like a cool project.

I have heard the LaFigaro 339 is a great amp for HD650.

If I don’t want to bend the metal parts to loose the headband, but just make it enlarge by put it in the middle of some books or else for a couple of nights, I need to extend the metal parts all or just set them how I use it when fitting into my head?

Hope my english was clear, just want avoid to damage them.

Must have made quite an impression, you've mentioned it 15 times in the last month.

Sorry about that. I will try to refrain. I want to try them on a Bottlehead Crack.

Is everybody amping their HD 650s, or are there other DAPs/sources people are using?

In a pinch I've used my Fiio X3 and while they get the HD650 to my listening level (65-75dB) the sound is slightly flat (less dynamic) compared to what they sound like on my Lyr2, Ember or BH Crack.

After hearing them on my LPG, I am very excited to finally get to hear them on a Bottlehead Crack 1.1 Speedball amplifier.

Some say just by use they will clamp less but for me I had to extend the metal sliders and bend them slightly but I tried to bend them closer to the ear cups so the sliders would still slide in and out correctly. Tyll likes to bend the center of the headband but I think this might cause the paint to crack/chip.

The benefit of bending (slightly) the metal extenders is two fold; reduced wear on the pads, and better comfort due to less clamping force. I bent mine slightly and they fully extend and retract without issue. Just don't bend them straight and expect them to retract properly.

Take the tips of your fingers and thumb to avoid using your whole hand then swing them in a U shape pattern to the left and right respectively. Bends them easily without worrying about putting too much pressure.

I guess I am just fortunate that I like the clamping pressure of the HD650 just how it is. I have a big head as well.
