Very fitting that update 10 marks the introduction of XTC, 10 years after MDPC-X introduced the original blackest black sleeving.
It came as quite a surprise when Nils announced a second sleeve was on the way, I had to try it so rather than just starting with a little sample I figured 100m was required to get to know it.
And as i'm sure many know already, sometimes it's quite difficult to just 'stop' adding MDPC-X items to the cart. So 100m of 15AWG which i've yet to properly try out, 1000 15AWG crimps then seemed obvious, 1000 shrinks.. because and then a CTX3 naturally as I seem to be getting 15AWG everything. Then all the new dupont stuff... plus some Carbon-BTI for imersa.
So about 3 minutes into try that new sleeve and chill...
Four identical wires, two sleeved with classic small black, two sleeved with XTC black.
The difference is certainly a subtle one and a mere civilian would be hard pressed to tell the difference on looks alone. Which is definitely a good thing. When stretched to the maximum they both hold onto the 15AWG wire with ease, no discernible difference to melt and as demonstrated both absolutely glorious to train.
So which would I recommend you may ask? Well in the hands of an experienced user they are both equally capable, classic is slightly more versatile as it will expand around much larger wires and terminals as needed. XTC however is extremely reluctant to change diameter or length making it effortless to obtain maximum stretch on a single PSU wire. So for new users doing purely 15AWG PSU wires XTC is easier to get tight results that hold shape. If you've got a huge collection of classic MDPC-X and some skills to go with it then I see no reason to run out and replace it all immediately, but do try XTC!
For ALUMIA I will definitely be using XTC, perhaps after 70 or 80 wires i'll change my opinion but the fractionally denser and rougher texture will certainly fit in. Also, it will be entirely black with the Noctua brown fan corners being the only 'colour' in the build.
