Highly recommend Mogami as a primary cable. My experience is they dont' subtract anything, while high-end speakers rely on some subtraction to create more imaging or detail. Markertek has both single and quad types.
Speaker Cables : Moderate priced
I am about to embark on upgrading speaker cables ( long over due ). Currently use Tributaries 12 awg UL copper cable. I need a long run for one speaker ( about 20 feet) and this has impacted the budget. I hope to spend around 1500 dollars. Looking for a musical tonally rich sound. I am not a detail nut.
Looking at the usual options: triode Wire, Audio Art Copper, Ice Age, Luna cables to name a few.
Wonder what the crowd has experienced in this price range; and open to new suggestions.
