From what you've described, these canal phones sound (pun intended) great! A few things are preventing me from getting it.
1. Price - if they're only in Japan right now, I'd rather not pay through the teeth on all the custom and duty fees I can see myself paying to Canada Post. As well, for $180, I think I'd rather splurge a bit more, and move to Sleek Audio's SA6.
2. Semi-open design - I like maximum isolation, and would prefer a totally closed design. My Atrio's with Comply foams provide me with a seal that's better than anything else I've tried so far.
3. Balance - You're saying that that the Victors are best when directly from the source, and that through an LOD iPod, the bass was overkill. As someone who uses a portable amp (RSA Tomahawk, no knob to control bass), that's a tad discouraging to hear, since my Atrio's perform remarkably with my amp (surprisingly, the amp doesn't overkill my bass levels on my Atrios, but refines my lows, and warms up the mids and highs).
4. Wood + moisture = potential warping? Since it is of partial wood construction, and stuck directly into your ear, I can see potential issues after heavy usage in higher temperature (ie: the heat of summer), with the wood possibly warping from the sweat and humidity of our ears. I know my IEM tips often come out sweaty in the summer, especially after a long listening session. Even if it's got a layer of anti-moisture coating on the outside, the internal moisture buildup in rapid temperature changes or humid conditions may even cause warping from the inside out. This will be interesting to observe.
