Which cable

Even my wife noticed ... isnt that the truth. Haha . Such an improvement was made even a non liar noticed the difference !!

But could she hear it all the way from the kitchen? 

They hear everything. 

Glupsom, it's a G2711 super 2,  cassette, radio record player. In its day it was great piece of kit  but it's overdue a speaker upgrade,  hence the mega bass 3000's
I have tried the bell wire and all fine, it's the positioning of the speakers which is now the problem. There quite big and there's very little space in my lounge, so I've got one ontop of the washing machine and the other behind the sofa.
There's a bit of vibration when on a spin cycle and so looking for a solution.

With all due respect, garbage will sound garbage regardless of cables you use
