By now, if you've smelled enough genuine top shelf incense-grade ouds, you will have noticed they all share a certain  common note in the heart and base... an unquenchably addictive steely-bluish-purple-floral-zingy-cola-pepper note that simply cannot be achieved using distillation tricks.
Myitkyina 4K has that in spades.

Myitkyina (pronounced "Mee-chee-nah").
If you're a serious oud collector, just the name should be enough to warrant your attention. The fact that this oil was distilled from incense-grade juicy black Myitkyinese agarwood... all the more reason.

Like all of our oils with "4K" in the name, this is the textbook-definition scent profile of the jungle it hails from. This is the crown jewel of Myitkyina; I personally do not know of any (factually-proven) Myitkyinese oil ever distilled from such high grade wood. As is always the case, the higher the grade of wood, the truer-to-life the oil's scent will be.
And Myitkyina 4K smells like old-world Super-King-grade Myitkyinese agarwood, heated Kodo-style.

Take the scent profile of Myanma Gold, and stretch out the peaks and valleys of the aromatic spectrum. The top notes are more effulgent, the heart is massively thick and round, and the base... oh the base! Packed with the steely bluish-purple narcotic incense chords which only wood above a certain grade can bequeath to an oil.

As was the case with Myanma Gold (but even more so here), the intrinsic scent profile of far-north Myanma agarwood naturally has a ton of overlaps with Kinam/Kyara. Like the former, I'm sure many will question why I didn't don this oil with the "Special K" title especially considering the large amounts of overlaps with Yellow and Green Kyara (particularly the cooling green, honey, cinnamon and tea-like notes).
The reason is simple: I'm very picky. And this is itself the textbook-definition scent profile of (non-Kyara) Myitkyinese agarwood.

Note: lighter applications smell more like classic Myitkyinese agarwood. Only with heavier applications, I would in fact classify the aroma as 'Special K' because of which notes suddenly get more pronounced (and the 🧠⚡️.... whooooh, boy!). Closer to Yellow Kyara, but with some elements of Hainanese Green Kyara as well.

Kham Lao and Myanma Gold were both high grade distillations, and they were immensely popular and widely acclaimed.
(quick refresher, I categorize oil grades as: intro, medium, high, royal, and ultra royal)
If you're ready to push the envelope and ascend nose-first into the world of topmost-shelf oud (full-blown royal grade), M4K is your first-class ticket.
