Will a 20k pot work in a BHC without any retrofitting?
Is it a direct replacement?
Yeah. That's what I've got in mine now - a 20k stepped attenuator. No problem whatsoever.

Has anyone compared this kit to the pass labs ACP+ ? I've been enjoying the acp+ for a while but looking for something differenct.. thanks!

The ACP is a solid state amp correct? I have not had experience with the ACP but it looks cool. Is the sound neutral, meaning no color like a tube amp?
I would be interested in comparing the starving student model to BHC.

Firstly I'm not able to compare the ACP+ directly to the Crack but have owned the Bottlehead Crack, Sex and Mainline and the original ACA which I used to drive my Hifiman HE6 paired with a Bottlehead Quickie (pre amp) with excellent results.

I have always thought the ACA more comparable sonically to the Bottlehead Sex amp than the Crack. The Sex being a little bit sweeter in the mid range and the ACA being faster and more controlled in the bass.

Sonically especially in stock
non speedball form I would expect the Crack to offer quiet a different presentation to the ACA+ may perhaps be a step backwards technically but am only basing that view on my experience with the ACA not the ACA+

The Crack is a rewarding project hot rodding and tube rolling add further dimensions as does connecting with the Bottlehead community here and on the BHF.

An absolutely self-indulgent and purposeless "upgrade" to my BHC. Why, you ask? Because I'm a fan of Hard Rock! Yes, I'll be using this pun quite often moving forward...

Also, please recommend some feet that would go nice with this!

Dude - way to be different!! I would probably get some decorative feet to make a true statement piece. This Etsy seller has some wild “jewelry box legs”: https://etsy.me/2NjvjYh

Some of my favorites:

I absolutely love that! Play some ‘heavy’ metal with all the rock! maybe some stones?

What type of stone is that? Soapstone? Marble? Granite? Must have some heft to it.

I have both on my desk currently, and tbh we are not really comparing apples to apples. since one is OTL tube amp and the other SS amp with a small SMPS. Having said that, ACP+ does have that euphoric almost tube like sound signature and its much cheaper and easier to build (the resistor matching part is a bit of a pain... but thats another story). I'd say if you have high impedance HPs like the Sens HD stuff, go with the BHC, and if you have a range of HPs with different impedances, I would highly recommend the other amp on diyaudiostore, namely Whammy.
