Evolution acoustics mm2 umbilical upgrade

[fusion]

Evolution Acoustics MM2. Is there an upgrade for the umbilical cable. I have been using the intial neutric cables. Is there one that actually makes the speaker better

there are different levels for those cables, not sure Kevin Malmgren, the manufacturer, still offers them.

never compared the two levels, so I cannot comment on that.
