Ah - my apologies then. I misunderstood some things about the topology. Thanks for the correction, Doc.
I've just tried Bottlehead Crack (Speedball, 5998) -> Audio GD SA-31 -> HE-500, and it sounds excellent, with a little bit of a bass increase, added warmth, and generally just very pleasant. .
It's not a very efficient use of equipment, though, and not the chain I'm looking for. I hope to sell the SA-31 and replace it with something without input selection, volume control and all of that, just plain amplification - a headphone power amp - but there doesn't seem to be such a product category..

Small question here: How should I describe Bottlehead Crack OTL Kit at customs for calculation of TAX?
Amplifier? Tubes and cables?
Guys, what are the very basic skills needed to DIY Crack aside from soldering and wire stripping?
So... my soldering iron has been idle for too long and I want to build a Bottlehead crack.
For my cans (HD700) the output impedance of the Crack is probably borderline high (cans are 150ohm at 1000Hz with higher impedance at lower frequencies), but I already own a good SS amp and prefer to build an OTL rather than a hybrid.
I'm adding a DC offset protection circuit (AMB ε12) for peace of mind and a tube guard for the preamp tube which seems a little close to the volume knob and headphone cord:
Question: Can anyone recommend film caps for the output stage that will still fit comfortably in the case?
Thanks!
Thanks JamieMcC & Skepic! I will make a choice based on your suggestions. Don't want to spend a fortune on boutique caps, those look reasonably priced.
Also contemplating adding a USB port with a GrubDAC with an metal input toggle switch (if it ain't broke, it doesn't have enough features yet haha), but still on the fence about adding a digital input to a "retro" amp.
