Please keep in mind, that the grade of wiring used internally with your Zerius speakers is that of the Triangle TC2250 2.5 mm2 oxygen-free multi-strand copper flat loudspeaker cable.
I would seriously consider using equal appropriate lengths of the TC2250 speaker cabling to your integrated tube amplifier, for the maximum permissible performance.
