I find it a bit odd that someone who owns Weiss and EAR has no idea about interconnects, because they're pretty sophisticated components. But if you never fooled around with cables, I suggest you buy a couple of pairs of ICs from Blue Jeans for about $30/pair and listen for a few months. They are good, pro-quality cables and will give you a baseline. Later on, you can try some higher-priced cables and see if you think they're better. Without a baseline, you have no way to know. As to the "10% rule", I think that may be good advice when you're purchasing a new system and you're on a tight buget, but I have used expensive cables on cheaper components and found they made a huge improvement. If you're of a mind to move ahead right now, I would look for a pair of used Audience AU24s, which are great cables for the price. The older models are excellent and the company has great customer service when you need it.
RCA interconnect recommendation
Would like recommendations for interconnects for both analog and digital side to an integrated Rogue Cronus amp from a Nottingham/EAR 834P on one side and an Antelope Zodiac DAC on the other side. What should I be looking at and what kind of budget should I set. I'm thinking up to $500 for a pair but have no idea. Thanks for all advice.
