“I am using a 28 year old Pioneer A300R Precision amplifier instead of my TAD pre and power amps until My amp is repaired. I Fitted one of the silver diamond power cables to my Pioneer PD-70AE SACD player, the quality of sound from the two pioneers is incredible. The SACD player is really good but with the silver diamond power cable it has been transformed. There is no way you would think that you are listening to a £400 amplifier. The cables keep getting better and better.”
