Duelund internal speaker wire?

I have had many recommendations I replace the internal wire in my vintage speakers with Duelund, but have not at this point.  I have used Dueland as speaker wire and thought it was very good. So depending on the speaker, I think it could be a good move. 

I’m using Audio BBQ Duelund ICs purchased here on Audiogon which I like very much (16ga?). Now considering speaker cables (12ga?) which made me wonder about the possibility of Duelund internal speaker wire.

I rewired my Lowther speakers with Dueland wire a couple (maybe 3) years ago and it was a nice improvement in SQ. 

It´s Duelund and not Dueland.

..just as an aside....I spoke to Richard Vandersteen about this very thing.  He said that they extensively use many different wire to make their speakers sound the best...sometimes wire with non"audiophile" credentials are better for a specific application. As an example....their speaker connections are small and non"audiophile", but have been proven to sound the best.....just sayin'

I have owned Duelund rich nice but not the most detailed . much better is the VH Audio 8 conductor 
small solid core awg21 of Occ Copper 6-9s and foamed Thin Teflon dielectric ,litz Wire.a bit of a bitch to unravel the Litz  to seperate the wire  leads,natural cotton centercore , veryvery clean detail  and open a awg12 gauge I highly recommend get away from Brass  connectors outof your system speaker terminals ,wires,and  equipment, goldover Copper Smuch better, more natural.
this wire is roughly $31 a foot about $360 for 6ft pr then connectors ,the Oyaide Gold Copper Spades are only $60
thesebeat cables well over $1500-2k ittook about4-5 hrs to make them . Runin time 4-500 hours. 

I know this is not the same as changing internal wiring,bu

I respect audioman58, but could not disagree more. The Duelund wire is naturally toned and beautifully resolving....not in the traditional Hifi or high end manner however. It does not shout out ....pay attention to me! Rather it allows the listener to engage in the music as it unfolds unforced and natural.

I have used it inside many speakers with great results. Fantastic results. The 12gauge on bass drivers, 16 gauge on mid drivers and 20 gauge on the tweeters.

Yes, I build and sell a line of cables using Duelund bulk wire ranging from usb cables to power cords. Duelund is Easily the best value I have ever heard in cabling.

If you are looking for razor sharp leading edges and lighting fast sonics, if these are your sonic priorities, then you may be better served elsewhere.

If your sonic priorities are perfect tone, realism and a smooth unforced flow, then Duelund is for you.

I agree with what grannyring is saying. In one of my setups i  have an old tannoy system 1200 for which we used internal duelund silver along with duelund xover parts.

Not sure which spk internal cable you wish to upgrade but the main question you should be asking is what you would like to achieve with this upgrade.
All the best.
cheers

+2 with Grannyring. I've used 12ga Duelund tinned copper from my MC30's to the external crossovers solderless copper lugs and 12ga to the woofer plus 16ga to the tweeters on the Tannoy MG HPD315's and find the sound quality to be everything Grannyring has described. I also modified the speaker binding posts to eliminate solder joints by using binding posts to only clamp internal wires to those from the crossovers. 

I must say I've never understood upgrades to speaker cables and ignoring internal speaker wiring.
