Interesting how that natural walnut seems different in colour somewhat from light source to light source. First it looks like a nice even grey brown but then it takes on a real orange tint.
In the Axiom deals pages, it looks much more orange on some units (for example: https://www.axiomaudio.com/arb-0129).

This is making it tough to consider the espresso or not. We don't want it super dark brown, love the natural walnut look, but do NOT want any of that orange. I already have some Tannoys with a cherrywood finish that have 'oranged' over time. I have a pair of old Mission 737r in walnut that also have that orange look (i was going to refinish them).

Hmm, almost starting to wonder if we're coming back full circle to Boston Cherry. I think the Bordeaux might be too red/purplish from what i've read. The Cherry chestnut was another possibility but wondering if it is too red.
