Would like to replace the mains cable supplied for my ROTEL-RMB 1075 amplifier. Have been looking through the Russ Andrews/and other web sites for information, but still remain confused as to the "way forward". Will a more expensive cable (£80 - 120) make a real difference to sound quality etc. If so, which type/manufacturer should I research? Appreciate such a question can be very subjective, however, any help you can give wqould be VERY MUCH APPRECIATED. THANKS!!!!
