I’m considering upgrading my speakers internal wiring

Why don't you call him up and ask if he thinks that is a good idea. 

You have fully broken them in and know exactly what they sound like? If not make sure you have at least 500 hours on them and many of those listening. Cardas is likely to sound a bit warmer... is that what you want?

Asking the designer for his thoughts seems prudent if it’s an option. There may be more to the internal wire than meets the eye.

Most speakers use fairly pedestrian internal wire, and normally I’m all for parts upgrades, but in this case, I’m not so sure. He used a lot of really good crossover parts. On the other hand, it is reversible if you don’t like it, so if you’re up to the cost and time, that’s all that’s really at stake.

When I open my Norh9 speakers I did not like the wire inside. I replaced the wire with siltech . The sound did improve . So my advise keep the original wire, in case it does not work . Also take a picture.

I replaced all my internal wiring with Duelund DCA oil cotton insulated wire in 10 awg for the bass drivers and 16 awg for everything else. I did this while I was upgrading the crossovers.

A dirty little secret is that almost evey speaker saves money on crossover components since they are inside and invisble. I’ve seen speakers that put their crossovers on the back under plexiglass to brag about how good their components were and they were merely mediocre. Most have plain old sand cast resistors like they used to sell in radioshack for 15c. This is a fertile ground for upgrade.

Those suggesting that you should call the OEM and ask should put yourself in the shoes of the OEM. Most will say it is not necessary as to say otherwise admits their product can be improved. Many will worry you’ll break something and then ask them to fix it since they approved the modification. YOu’ll almost always get a negative reply. which is good if you don’t really want to do it anyway

I got so many negative comments when I upgraded my crossovers that I think many people are just hoping crossover upgrades don't become a trend because then they will have to do it.

Peter is a great guy and I have a very good relationship with him and respect his build quality and craftsmanship. This is not an insult or point to a flaw. Only my own OCD and thinking it has to enhance the sound quality but is not essential to a speaker builder. I’ll call him and get his opinion and I know his honesty will be true.
