What wire are you guys using to re wire/upgrade the wire in the cabinets themselves. I have done some searching before posting and there are wildly different opinions about this. Of course, because its about wire! I read that some have used 14 AWG marine tin coated copper and that sounds like a affordable option to me at $10.00 per 25 ft in any color. Eventually I want to 1. Buy Gimpod boards to re build my crossovers or 2. build my own point to point on wood boards that I would mount inside the cabs. At that time I would need re wire the cabinets. So what do you guys use ? Thanks.

    yep, depending on what model you are doing, I recommend trying to keep them in the jacket as much as you can.

    If you go point to point, you can combine certain wires to consolidate everything to the jacket. IE: 1.2TL you can do 5 wires (+jumpers) versus 8

    Gmcman used Cardas. I like Furutech. Ray used Audioquest Go 4.

    I used Furutech per your recommendation on my SDA1 signatures and SDA2a. Then when i went to use it again on another project it had tripled in price to 12-15 dollars a meter from a little over 4.00 a meter.
    No complaints here but the price put me off when they raised it. I haven't looked in a long time i do not know if parts connexion carries it any more.

    Looks like you cats like stranded wire. I guess that is what came in there and most speakers for that matter. I will be doing up a set of SDA 2B's when I do it. I have also thought of doing the Snells and the AR 3's but right now I gotta work on the Polks and get them running right. They are the main speakers I listen to.

    I bought a spool of 12-gauge, silver-plated copper w/ Teflon jacket. Haven't installed it, yet.

    Price "can" be reasonable on eBay as it's military/aviation surplus.

    Multitude of posts saying many folks have done this but, not many comments for/against sound difference. Anyone believe it does make a difference?

    Of course it makes a difference. The important questions are: 1) Does it make a significant (audible) difference, 2) is it an "improvement" or just a "difference", and 3) Is the cost-to-benefit ratio acceptable?

    All differences in the "sound" of wiring are due to L, C, R, plus noise of the conductor(s). There is NO magic.

    I get that. ;) Kind of hoping to see some quantifying of said differences. Some actual experiences and what people think. B)

    I went from 30 YO stock wiring to Cardas Litz 15.5 Ga and the difference was dramatic. I tried to A/B the left to the right, one being stock and one upgraded to the Litz, and the tonal difference was enough that you couldn't really listen to both at the same time...was all over the place.

    I also soldered my speaker terminals, not sure how much difference that made, but safe bet the wire was responsible for most of it.

    This thread was very timely for me as I am about to embark on upgrading my SDA 1B binding posts and didn't want to re-use the original internal wiring. Have ordered and received the Cardas posts from Soniccraft and was contemplating the best way to connect them to the upgraded crossovers. I just ordered some 14 AWG silver coated wiring from Ebay. Thanks Schurkey.

    Will be using that wire to secure binding posts to the crossover network.

    I will be finishing up a rewire for my 2.3TL's today. I opted to use the Supra Rondo for the project. My preamp is in the shop atm, so I can't give them a listen until it's back in place.

    Looking forward to any improvements the fresh wire will bring.

    How many feet did this project take?

    I purchased 104 ft. for both speakers, including binding post to x-overs. Looks like I'm going to have about 6 ft. left over.

    A 100 ft. should catch it, but I wanted to make sure. I will utilize the excess on other speakers...providing this upgrade does make a difference.

    I usually do 40 ft of the 4 conductor rondo for a Pair of speakers, noting you can do the 2.3tl with 4 wires for the tweeters versus 6, taking a single 4 conductor run, which looks great

    When I do mine I am thinking of soldering all my wire directly to the x over and the binding posts as well. At the speakers would be a different story. There I will use crimp connectors soldered to the internal wiring.

    The AudioQuest GO-4 wire I installed in my SDA 1.2TLs is solid core wire in a "hyper Litz" configuration: each 15 AWG conductor is a twisted pair of a 17 AWG and a 20 AWG conductor.

    The Cardas wire I installed in my SDA SRSs and SDA CRS+s is stranded, individually insulated Litz wire, for an effective wire gauge of 15.5 AWG.

    Yes, rewiring my SDAs provided audible improvements in sound quality. I have rewired my 1.2TLs twice. First with Cardas wire, then with AudioQuest GO-4. Details are in these threads:

    Ordered the 15 g Supra from Madisound. Now I am thinking that may have been a mistake. The stock stuff is 14 best I recall. Should I use it or re order something larger gauge ?

    Most stock wire is 16ga unless the big SDA 1.2 size all used larger. I thought some older pictures showed a rope lay 12 ga. Type

    My 2.3tls had 16 ga. I went larger to 14ga when I rewired mine.

    So I guess with a pair of SDA 2B's 15 ga. should be OK. Thanks @pitdogg2 .
    This is what I ordered and that came in yesterday .

    I don't know. Tinned makes it easier to solder but defeats the capability of OFC (or better) copper runs.
