I am noticing the harder woods seem to accentuate bass, so perhaps the softer, more sound resonant wood will calm the bass - without affecting the other registers. It also looks like walnut is used everywhere except the sound chamber, where there is a tube of a lighter hard wood (alder, maple, or cherry are my guesses, due to the grain renderings in the marketing images) which is the primary sound wood, so who knows? Looks like the primary issue was machineability, though these are traditional sound woods in guitars and headphones. So, yes, we'll see.

now that is something we are all looking forward to.are you looking to replicate the R10 with the CD3000 housing, but wooden cups? or am i mistaken?

Precisely - I am intrigued by the JVC drivers as they are direct mount, but think walnut is the entirely wrong material for musical resonance (MY opinion), so from what I have seen of the R-10 interior, I am making some practical machining decisions - one being to NOT hollow out the entire cavern, and simply put another cap with sound holes to hold the driver.

If this doesn't yield acceptable results, I have an additional slab of Siberian elm, 35 years old, grown in a cold climate to yield smaller tight rings.

So, here is the question to all: What drivers should I try? The JVC is on as it is direct mount (a really good thing, IMHO), the CD3k drivers, and a set of W100 drivers (some of my favorite closed can drivers). Not sure I wouldn't have to make another set of housings for other drivers, but what the heck? It's only time, and cheap therapy for me.

The goal is to approach R-10. Oh, and balanced only - nothing else is on my radar. Sorry, a REALLY STRONG personal bias.

Interior
Exterior - still a lot of hand work to do.

Edit: Does anyone know the R-10 finish? I am assuming oil, and what I will be using regardless - 10 or so coats.

I had one R10 that had a bad driver. Since that one was imported through EIFL, I was able to send it back to Koji and he arranged the repair. That was still under warranty, though. Still, he may have contacts in Sony Japan that can do the repair. Expect a long delay in any repair sent to Sony Japan, though, if they'll do it at all.

Yeah, I bought my R10's from Koji.
