I purchased 1.8mm and 0.79mm Mundorf Angelique to rewire my Snell E3 speakers.
Original Snell cable is nothing special, possible 12AWG twisted multi strand copper.
Mundorf is very stiff and hard to work with, and very hard on speaker connectors, so care ash to be taken while moving drivers with soldered cable.
It's also very hard to domestically twist 2 runs of the cable, as it twist more at the start and then further it become uneven, while if you twist more, you will apply to much pressure on the PVC so it breaks.
After 20h of initial listening I was hoping for more, but nothing changes.
The sound is dull, lacking definition and resolution, with poor soundstage. Everything became closed in. There is not much air and ambience, or textural richness. Tones are ending quicker then they should be without any pleasant overtones.
I like smooth sound too, but it must not lack definition, and clarity. This is nowhere near smoothness. It's too polite. Perhaps it would work slightly better on extremely bright, and harsh system, but if your system is neutral you should choose something else in my opinion.
When it comes to Audiphonics service, its one of the best, as usual. Great communication, great choice, reasonable pricing and fast delivery. 5 stars for the service. 1 - 2 stars for this cable.

Incroyable.
J'étais un peu sur la réserve concernant le monobrin, je l'ai utilisé pour recâbler le woofer de mes enceintes et ce câble après une dizaine d'heures est d'une précision et d'une délicatesse que je n'aurai imaginé. Très belle surprise.

A great sounding wiring cable
I have implemented and tested a large number of jumper wires between my speakers and the SPEC real sound processors which I use. Different brands of silver and copper wires with different dimensions and designs by several brands have been tested, including all the various Neotech OCC-types available. The Mundorf ACW115BK wiring cable provides a large step forward regarding resolution, 3D dimesionality, organic presentation and low to high frequency response. This is the most musical jumper wire I have used for this purpose in my system. I am really impressed with the excellent resolution and silence offered by this Mundorf product.
