Ok, sounds like a secret weapon.
Or it is not ROHS compliant.
I'm betting on B between your choices. Or it might even be that they haven't bothered getting a CE mark
As to the cables and buffer devices.
For a buffer device to work so as to negate the effects of the cable, it's got to be at the guitar end. Any tone loss due to capacitance of the cable cannot be magically restored so it's guitar end or nowhere
As soon as you hit a nice high impedance device then the tone suck stops. This can be the input of your amp OR an effects pedal with buffered bypass.
The thing to stop you using a buffer at the guitar end? Vintage-style fuzz pedals and wah pedals (real ones, not modelling :)). Vintage fuzz circuits when 'on' are low input impedance and naturally suck tone. The designers thought of that and made them brighter than they should be to compensate. So if you use a buffered device *before* the fuzz, the fuzz will sound shrill and horrible. IMO anyway And wah pedals just sound messed up after a buffer.
So for me, I use a very low impedance cable and again they're not expensive. A 3m Klotz La Grange is under 30 Euros and that will do the trick, or it does for me anyway When I built effects pedals for a hobby (which I'll probably come back to at some point) I had a board full of home made stuff plus a few commercials. The first thing in the chain was my wah, then a couple of vintage fuzz. All had been modified to true bypass but even so it adds SOME capacitance but it was acceptable. Then it went to a home made Klon Centaur which has a very nice buffer circuit. It worked a treat
