PRR : in fact, i can get more uf for the money with BG. For 19€ a pop (best price i found, and it's in Belgium), I've the choice between 150uf of BG VK or 82uf of Audyn mkp-qs.
Furthermore, jeffreyj on head-fi made a good point with the possibly erratic load of the K340, rulling out 47uf. So, i shot for safety with the BG.

Why aim as low as 10Hz?
I wonder, are headphones really able to produce 10Hz? or even 30Hz for that matter? I mean, in a manner one could really notice?
I don't like too much elcos at the output. And don't understand what's all that hype for Elnas, BGs, etc.
I had a couple Cerafines at a CF OTL headphone amp, and ok, there's bass certainly (dunno if it's there or is the cap adding some on its own) but there's also "graininess" in the mids.
Yes, I tried bypassing them with quality 1/100 musicaps, audionotes or generic quality MKPs (RIFA I believe) but the graininess didn't go. I also left them for time for "run-in".
Even worse, Panasonic FCs sounded and measured better. Slightly less bass (though cleaner) and much less "grain".
My point is: are going below 20-30Hz worth for headphones? As I see them: there's much benefit from using MKPs here, as they don't suffer from those distortions and will last forever without changing its sonic qualities, not to speak for prices, being cheap alternatives available.
I have now a couple SCPs (solens) 600V/47uF MKPs and they give the cleanest sound I¡ve listened through this amp. They cost about $19.
Wonder if using a cheap alternative like motor start types (they're usually up to 450V/25uF 5%), and even parallelling them will be on most aspects superior to those exotic ($130 for a cap? no way!) electrolitics.
Those caps run for about $6 at your nearest home electronic appliances repair shops (used on washing machines, refrigerators, etc).

bulk for sure but...
Yes, the bulk is unavoidable
I revised a post I did in the past regarding this and forgot that ratings go usually to 47uF max in the 400-500V range, but reach 330uF in the 220V range, which I believe is very suitable for medium to high Z headphone OTL amp output caps. No need to parallel...
They're usually below $6 a piece, so you probably can't beat those $12 for a couple of 330uF/220V MKP caps.

Electric home appliances spare/repair shops
Look for shops that carry spare parts (or repair) washing machines, refrigerators, and the like: i.e. knobs, handles, seals, pipe adaptors, etc.
I live in a "small" town (about 150.000 people) and there are a couple shops that carry this kind of things.
Those caps are used to start electrical motors...
