Internal Speaker Cabling

I totally agree,my 6.9 Norh speakers are so beautiful.
But upon opening,the wiring ,used inside, I could tell it
compromise the sound,so I decided to use my siltech
wire, to rewire it, the result in unbelievable.I dont
blame Norh though, the speakers are only $950 shipped.
No way they can use siltech for their asking price.

Yes! Upgrade internal speaker wiring. Madisound indicates the use of Nordost Flatline (rectangular conductors, teflon dialectric), my friend made kit speakers with this wire and they sound more alive/spacious than the same speakers I made with Audioquest Indigo Litz.
Avoid usage of thick, hard to manipulate cable, sucks to work with in enclosures. I have seen the inside of dynaudio speakers (contour/evidence)..that use 12ga zip cord! Due to all the oxygen which can penetrate stranded cheap zip cord..I have seen this wire turn green (oxidize) in 5 yrs.
The best cable I have tried has always been solid core conductors (rectangular or round) with teflon insulation. Exotic arrangements of conductors (litz) don't seem to really improve sonics that much.
I suppose your only concern here is, that speaker designers voiced their designs with whatever wiring they used..so using different wire could throw off their initial voicing. However..if dynaudio uses zipcord..you can discount their engineers belief/understanding of the effects of wiring. Their speakers sound dry and lifless anyway.

Something else to ponder are the quality of the binding posts at the speaker and at the amp,they can also alter the sound of those expensive cables.I like to simply bypass the binding posts whenever I can.If the speaker cable and the internal speaker wire are terminated in spades, it is very simple to use a copper or brass bolt and nut and clamp the two spades one on top of the other.If the internal wiring is not spade terminated it is easy to do this and a wise man would opt to match the spades so that all are the same.

Not to be condescending, but it makes no less sense to buy good speaker cable regardless of the internal wiring, than it does to buy a good CDP.

Many people don't want to get their hands dirty with mods, but anyone can hear the improvement with better cables or better CDPs. Whatever people can justify spending to improve the sound of their system is a worthwhile endevor...

The weakest link should be the next thing to improve, but sometimes links get missed because they are not obvious.

You are certainly wrong when you intimate that speaker manufacturers don't pay much attention to the interanl cables. There are as many divergant opinions about cables as there are speaker design, but most speaker makers are very much aware of the internals.

BUT some speaker makers spend the money where it shows, while others spend it where it sounds...

Another way to view this ..is the fact that only a couple feet of wire is used internally, so it dosen't matter as much as the much longer run of external speaker wire.
A funny fact: when I (and others I know) used to use 12ga zip cord for speaker cable years ago..we would occasionally hear police radio transmissions through our systems as a cop car drove by. The idea being..zipcord is 2 parallel unshielded conductors..which acts like a RF antenna, especially when run in a straight 10-20 foot line.
Nrchy: I know manufacturers pay attention to the internal wiring, I simply feel that some pay more attention than others..and I know there are engineers/enthusiasts who say that fancy speaker cabling is all hogwash. These are usually older people who have fixated ideas of what is and what is not..and their hearing is rolled off due to age, so they'll never hear the difference anyway. Oh yeah...and some of those are the same people who design speakers and have wrong opinions about wire.
