Hi Matt, if your thread lasted 30 minutes that must be a record! Naim don’t tolerate any postings about alternative Burndys or Snaics “because they carry power”, yet bizarrely they do allow other manufacturers’ power cables to be discussed...
At the level you’re at, the Burndys, Snaic and DIN-XLRs are all weak links and it’s well worth having a listen to the alternatives, as you’re only touching on the performance capabilities of your 552/500. Naim do have an SL version (designed and made by Vertere) of the latter but, although they’re certainly better than the stock items, are some way behind Chord Sarum T, which are much cheaper, and light years behind Chord Music, which are similarly priced.
Chord do snaics (“snakes”) in a variety of types - I was introduced to them by my dealer, having had to eat my words after dismissing them as “they only carry power to the display”. I bought a Sarum version as a result and that’s now been upgraded to Sarum T - another nice option when buying Chord.
And then there are the Burndys... You don’t need to spend £9000, you can spend £9000, but, as Nick found, you can spend rather less than half that (still a lot of cash admittedly) by concentrating on the 552. Come what may, you do need to hear what they do.
