Thoughts on swapping out Audioquest and Transparent cables for Duelund

I have both ICs and speaker cables made from Duelund wire, as well as multiple other ICs and speaker cables here.  This review is actually about TWL cables that are made from vintage Western Electric wire, which was the impetus for the Duelund wire.  They don’t sound exactly the same but I find the sonic descriptions in the review to be generally applicable to cables made from both WE wire and Duelund wire.

I find 16 awg to be a bit beefy for constructing ICs and my experience is that the 20 awg twisted pair Duelund wire would generally be better for ICs.  If you must use the 16 awg wire, you might try using ICs from the 20 awg wire from source to pre and ICs from the 16 awg wire from pre to amp(s).

Having a bunch of wire here, at least in my experience, which specific wire sounds best, and with which equipment, is a bit of a crapshoot.  If possible, don’t sell your existing cables until you can compare them directly with the Duelund cables.

BTW, if you are constructing the cables yourself, the twisted pair in a cotton casing is convenient to use but you may consider adding a shield outside the casing and then some form of techflex outside of the assembly. For single-ended ICs, I would connect the shield at the source end only.  For balanced, I would do the same and then add a counter-spiraled ground wire outside of the shield that is connected at both ends.  Others do it differently so YMMV.

IME, the WE or Duelund wire is sometimes but not always the best sounding option, but it is always a good-sounding option.

I too have the MOON 280D MIND2 streamer/ dac feeding  a REGA OSIRIS integrated amp, and driving my Brit speakers (HARBETH) 

 As you said, a warmer but still airy and very detailed audio presentation was missing. 

So I replaced my entire NORDOST FREY cables array by swapping in a full CARDAS CLEAR cables loom.…… - Terrific upgrade  …my quest was solved in spades .  
Highly recommended.

- NOTE: Balanced (XLR) CARDAS CLEAR  interconnects for the 280D as the source were preferred over RCAs

FWIW …

I prefer a “slightly” warmer sound, and while system is not bright if it were a tad warmer I wouldn’t mind.
 

Given what you’re looking for I can’t recommend these AZ Satori shotgun bi-wire cables strongly enough.  I’ve been using them for about 20 years and they’ve staved off all comers to date in their price range and above.  Maybe just a shade of natural warmth with organic tone, refined treble, and excellent imaging and expansive 3D soundstage — transparent yet natural sounding is how I’d describe them.  And at only $350, which is an insanely good deal, if they don’t work out you could likely turn around and sell them for a profit.  Just another potential idea to try FWIW, and best of luck.

Given your quest. I would recommend Cardas. Transparent... and for that matter Nordost tends to be too... sorry, transparent for that kind of equipment. I have owned Simm. I prefer buying well known brands that have considered all parts of the audio spectrum and optimized for the equipment it likely to be use for. Cardas is probably the best. They are also well reviewed and respected. So, if you become familiar with their products they are easy to choose and swap out over time.... as opposed to boutique companies. This stuff it too esoteric to make it harder by adding more variables.

FYI, I use all Transparent... and currently have no Cardas in my system. But earlier when I had lessor equipment Cardas was a mainstay providing great musical experience and detail. Companies like Nordost and Transparent strive for the most transparent and neutral sound at all levels. But that can easily sound lean, overly detailed and dry in mid or lower tier audio gear.
