My order of SpiralDot++ from MTMTAudio came today and I slapped a pair on the Semper (blue on silver). I haven't taken them out of my ears since. Been sitting here, listening to my jazz playlist on Tidal, fully immersed in music. Such great sound. On the one hand it's a pity Bob only made 99 of those, but on the other I'm glad to own one of them.

"amorphous", that's a really odd adjective to use, on a platform where precision and uniformity are expected. When you take into account the *synonyms: that's what I look for in a mid-priced IEM, a vague implementation, of the dynamic driver's composition.
*Synonyms:
shapeless
formless
unformed
unshaped
structureless
unstructured
indeterminate
indefinite
vague
**amor·phous | \ ə-ˈmȯr-fəs \
1a : having no definite form : shapeless an amorphous cloud mass. b : being without definite character or nature : unclassifiable an amorphous segment of society. c : lacking organization or unity an amorphous style of writing.

Nice! Yes there are literal translations - I'm married to a German so trust me I know - but then there's artistry of English, and in the context of music, with amorphous, I hear synonymous meanings like, liquid, formless, shapeless, flowing like water......
Anyway, I'm excited by what Bob is up to.

The language used to describe sound is nebulous enough as it is, with people ascribing different meanings and interpretations to things like, for example, bass quality and quantity. The ADLC is a term used to describe driver technology, so it should be precise and specific, not left up to the individual interpretation of each and every reader.

Been reading about ADLC and not sure whether below snipped from text if similar to what Bob is using, we are in for more immersive fun time with the new model. And the reason why BC is interesting coz ADLC will be covering the midrange and treble sections.
the amorphous diamond-like carbon coating (ADLC) defining a mixture of sp3-structure diamond and sp2-structural ure graphite carbon which can effectively enhance the details, clarity and fidelity of music based on the high hardness, excellent heat conductivity as well as treble vibration frequency up to 70 KHz, so as to satisfy the requirements of high-end market consumers.

I'm interested to see what Bob has come up with. Amorphous coatings are common in thin film applications like an IEM driver would have, and some have really interesting properties (being vague isn't one of them, it's a physics term). 
I'm also wondering how it differs from the DLC coatings other drivers have had previously.

My video review of Semper
I think it goes more in the direction of an amorphous solid, which means a non-crystallized solid material.

Correct, a solid material with no geometric crystalline structure. Glass is another example.

Semper playing out of my Shanling M6 over NiceHCK'S Dark Jade cable through the ddHifi 2.5 mm to 4.4 mm adapter. SpiralDot++ eartips. That's the Semper dolled-up all the way
Damn but this cable has a premium feel. Heavy, slightly rigid, and I like how the colour goes with the Semper shells. The 2-pin connectors are a bit on the long side so they protrude slightly from the sockets, but on the upside they fit without any filing.
Since I get all my balanced cables in 2.5 mm because of BTR5 I got the adapter to save on having to also get 4.4 mm cables for the M6 (I find the 4.4 mm port more secure). It does the job, fit on both ends is secure, but most importantly - I can hear no detrimental effect on sound.

It must be difficult to drum whilst doing long runs ! My respectsAnyway.. what would be your go-to albums for checking drum sounds?
I enjoy Joe Walsh - Country Fair [SACD] for tonality, Band of Gypsies - Machine Gun . . . a couple that I also have a quick check with on new IEMs. What are your favs ?
Difficult but not impossible if you are chased by listeners...
Eh, lucky is the man who can write in his language....My favs for drums are all well recorded albums in my music/albums collection. In particular i like Warren Zevon's album and "Running on empty" a live album by Jackson Browne with Russell Kunkel sitting on drums. Kunkel has a peculiar way to play drums and uses a "strange" heads tuning with deep and wide toms, snare and kick and crispy but very clean cymbals and Hi-Hat. Two other very good albums i like for their drum rendition are two Italian albums. Both are by Fabrizio De André and on both of them drummer is Ellade Bandini, if not the best one of the best italian drummers (no, i'm not Ellade
). The first album title is "Creuza De Ma'" (Path to the sea). This is an italian album but lyrics are not in italian, texts in Zeneise, the old language of my town, Genoa. The second title is "Le Nuvole" (The Clouds). Here lyrics are part in Zeneise, part in italian and a pair in neapolitan. They are both masterworks IMHO. Ending, another good album for general iem testing is "Rumours" by Fletwood Mac.

Nice cable. Where did you buy it? Is it pure silver or silver plated copper?Mail came in.

Drop has Linsoul's Nymph graphene coated 8 strand 5n OCC silver plated litz cable on sale from $119 to $70 if you don't mind waiting until March to get one. HERE is the Linsoul page with the info on it. I'm thinking of snagging one.
