There are no indents - having owned an Osprey, having multiple, long conversations with Dave and James, and purchasing several NOS tubes from Dave, I find it hard to believe there was any intentional misleading going on, especially for a low dollar product like their cables.
FWIW all Raven amps are supplied with the same power cables they sell online, not the $2 PC most others supply with their amps.
I'm glad you've had a good experience with them. I'd like to give them the benefit of the doubt as well, but we'll see if I get a response.
I get your point of "why bother with the low dollar items" but this doesn't exactly build trust in the brand for me - regardless of whether it was intentional or not. I would not purchase another product from them without a reasonable explanation for why this happened, as this would just leave me wondering what other corners they might cutting.
I'll definitely you know if I hear back from Raven Audio.
