Naim recommends their speaker wire for good reason; their amps need the capacitance from the Naim wire to stabilize the amp. They recommend a minimum of 3.5 meters per side to achieve this end. I was told this by a long-time Naim dealer. The same dealer said that there would be no positive gain from a different company's interconnect, but I've experimented with the Nordost Blue Heaven and I like them better than the stock ones. Heresy perhaps, but a friend who is also of the Naim flock had a similar experience with the Blue Heaven i-c. We both noticed tighter bass and slightly better definition. That being said, the Naim interconnects sound fine, so if one were to try a different i-c it would need to be of substantial quality to produce a positive result. (IMHO.) However, now that I've tried the Blue Heaven and liked it I would like to get an even better interconnect to see if the improvement continues.
