As for Subwoofer cables i will use a Monster Cable MC 400 SW...
At first i wanted that cables but it was very expensive (around 12 000yen/ 100 euro) for just one cable even i knew it was one of the best subwoofer cable i could buy.
So i ordered a Audio Technica subwoofer cables because it seemed already good quality for the price (4000 yen) especially compared with the usual low quality cables that come free with subwoofer.
But finally 5 meter was to short and that audio technica cable do not exist in 8 meter so finally i had another good reason to take the Monster Cable subwoofer cable :).
From left to right: "free subwoofer cable", "audio technica subwoofer cable" and "Monster Cable subwoofer cable"...
As usual Monster Cable quality of connectors is great, interesting point the center part of the cinch connector is cut in two part to keep pressure in the connexion.
The cable itself is a Solid core cable which mean its only one thick piece of cable instead of many small one, that make sense because low Frequency travel around the cable not inside, also one very important reason to take that Monster Cable for me was that its "Shielded" the audio technica cable was not.
It help protect the integrity of the signal and protect it from electrical interferences...
So to summarize... The Monster Cable was more expensive but iam glad and happy i got it :).
