I have never considered spending money on an expensive mains power conditioner or filter, but I did consider using a dedicated power cable with proper conductor diameter and shielding to connect the audio system directly to the main fuse box.
Generally, I think the electrical infrastructure here in Hamburg, Germany, is of good quality, and particularly in my home I have never experienced any problems related to the electricity supply. Despite this, I was aware that a cable with better conductivity and improved protection against electrical noise could potentially improve the performance of the system.
I also noticed that the wiring used to connect the wall power sockets with the main fuse box has a cross-section of 3 × 1.5 mm². Since the power cords for my amplifier and DAC use conductors with a cross-section of 3 × 2.5 mm², it seemed logical that the mains power cable supplying the audio system should have a corresponding diameter.
I know that some people would consider running a separate cable from the main fuse box to the audio system a little strange, but believe me, I have already experienced how even the smallest details can influence the performance of an audio system.
Japanese Hi-Fi enthusiasts have often pointed out that the quality of electricity is as important for a system’s performance as blood is for an organism. I was also curious to experience the effect of pure, unrestricted electricity, free from electrical noise.
After some research, my choice fell on the Ultimate Solidcore shielded power cable and Ultimate Pure Silver power distribution fuse from the German company HiFi Tuning.
The Ultimate Solidcore cable has a cross-section of 3 × 2.5 mm², separate copper shielding for the phase and neutral conductors, and polypropylene insulation designed to minimise capacitance. The Ultimate Pure Silver power fuse has undergone cryogenic treatment, which is intended to improve its conductive properties.
My plan was to connect my Groneberg six-way power distribution socket directly to the main fuse box using the Ultimate Solidcore cable and Ultimate Pure Silver power fuse.
After installing the power distribution fuse, I connected the phase conductor to it and attached the shielding to the ground bar inside the main fuse box. The same procedure was applied to the shielding of the neutral conductor, meaning that both shields were connected to ground at one end only.
At the other end, I connected the cable directly to the terminals of the Groneberg power socket, leaving the shields unconnected. After checking all connections with a multimeter, I plugged in the devices according to their absolute polarity and switched the system on.
The effects of the upgrade were easy to discern. The whole presentation sounded more solid. Large instruments such as piano and cello gained more weight, dynamics became more energetic, and both detail retrieval and three-dimensional spatial rendering improved.
The timbres of instruments and voices sounded more neutral than ever before, and ultimately every aspect of reproduction seemed to have taken another step forward.
As a conclusion, I would say that installing a dedicated power line to connect the audio system directly to the main electricity supply was well worth the effort. The result is a more relaxed presentation with improved three-dimensional characteristics.
Thank you for stopping by!
Excellent experience sharing thank you. I am aware of alternatives in this field however I agree with your experiences and appreciate the effort you took to make this instal. It can be a challenge actually impossible, to get new home builders to cooperate with such wiring even if you supply them the parts. This leaves you trying to do it post build which I find frustrating.
Bonne vision du système. Il me faudrait environ 20 metres de fil. Ici ont paye 33euro le metre cryo. Dinc 660frch. Le fusible lui, il est interdit en suisse de faire des modif electrique sans un l’électricien sertifié. Donc j ai fait autrement. J ai installé une double prise schuko dediée audio vidéo avec un boitier certifiés ch, trois sucre cryo.. Et du neotech 3.3m2 up occ monobrin, qui ma servi pour connecter les fils du mur. D’abord branché sur la première schuko puis de la sur la deuxième. Bizard ? Non car je branche un a/c enhancer de synergetics research. Donc il ameliore la qualité du courant genre schunt. Aucune limite de puissance mais une nette amelioration. Je branche mon cable d alimentation sr foundation 10awg branché sur mon conditionneur d isolation keces. Je rebranche mon installation. Les resultats ont depassé mes attentes sur tous les paramètres. Dynamique, naturelle des timbres sur les voix et instruments classique avec des transitoires plus net, realiste. Le bruit de fond est devenu plus faible et l image trois d plus realiste aussi. Ont est dans la salle live😉. La musicalité a fait un bon en avant. Les details deja present, deviennent plus present et mieux localisé, comme les hauteurs des pupitres de symphonie. Bref pour 500frch j ai gagner. En resumé selon notre syteme votre approche est exelente et coute relativement bon marché. Mon syteme etant trop loins, ma permis des exelentes amelioration pour un coût contenu. Se fils ultimate est exelent. J ai utilisé ce cordon pour un petit système pour une amie. Brancher une barrette DY avec un conditionneur keces de plus petite puissance, resultat impecable. Bravo
