That looks like very nice product for a very good price.
My only concern about it is the density of the connectors.
They are certainly too close together to use lugs, which I prefer. Bare wire ends could be used, but only if they are carefully formed into a question-mark shape and then tinned with solder, to prevent bare strands from shorting to an adjacent connector.
I guess I would use banana plugs to terminate the wires on both sides and plug them in. That would seem to be the easiest way to insure good connections and make sure there is no potential for shorting out.
Using banana plugs is also handy if you need to temporarily disconnect for vacuuming or realigning equipment.
