System: Arcam AVR300 amp, Marantz DV8300 CD, Monitor Audio Silver S6 and S1 speakers. I have the Silver S6 speakers connected with 'CYRUS high purity solid core speaker cable' I bought this years ago and can't remember how much it cost. The Silver S1 speakers are in the kitchen and are connected with Gale Electronics hyperlitz 250 - bought for cheapness as it is a long cable run. Is the CYRUS cable any good ? Would I be able to improve my sound by upgrading this cable ? What would you recommend (please give a cost indication also) ?
