Cardas Soldering Wire Quad Eutectic Silver Solder with rosin flux 1/4 lbs (113g) roll

I used this Soldering Wire and without any doubt is the best at moment available on the market. Most of people ignore the importance of a good soldering. You may use High Definition Cables, Gold Plated Connectors, etc. but they become useless if you dont connect them in the right way. In my humble opinion the Cardas Soldering Wire simply does not alter/modify the continuity of signal between a cable and a connector or any other component. And in addition it is so easy to use. Even with an economic solder.

I have used Cardas silver bearing solder on several tubed stereo amplifiers etc.that I have built. In fact, if I am building anything sound related I use this. Does it make a difference in sound quality? you may rightfully ask. I will say, Welp, I think it does, however you may not. But thats why I use it. I mean, plus, it IS really good solder. I have always been very pleased with anything I have purchased with the Cardas name so there you have it. I will absolutely buy more when this roll runs out.

Have used several solders to make audio cables. This one has a good pedigree, flows well and nicely priced as far as audiophile solders go.

What can I say, Cardas Quad Eutectic solder is by far the BEST out there. Hands down, I’ve tried them all. From cheap hobby store “silver solder” to the most expensive boutique brands. I restore/repair/upgrade/design Hi end Audio gear. Names like MCIntosh, Conrad Johnson, Cary, etc. equiptment that rivals cars in price sometimes. I need the best. Cardas is it. If you don’t understand the meaning/science behind Euctectic solder, look into it, the more you know. Great for beginners to start with, it’s very very easy to work with. Leaving perfect shiny solid solder work. I see a lot of “amateur soldering” and let me tell you. Most people who “can solder”, can’t. Make sure to use the correct iron, temp and procedure for your work. Also, a solid mechanical connection is always required. Wrap your wire/leads at least once. Use terminals or solder tags, and make sure nothing moves while the solder sets. I see so many cracked, failed, cold solder joints. Also with the Vintage gear becoming popular and everyone being a tech now and “re-capping”, I’m amazed some of these pieces of gear still work. People, just touching the two ends and soldering is not enough. J-hook or use a terminal to join. The joint should be sufficient even WITHOUT solder. The solder should only be needed to “lock” the mechanical joint once hardened. This stuff hardens equally across the metal combo, making for an incredibly safe, solid, secure joint. Ive used Cardas for over a decade and never an issue with a cold solder. I buy the 1lb rolls quite a bit as I use so much. However, a single $30 roll will last the normal hobbiest a lifetime. Nice and thin making waste less of an issue. Again, if you’re going to get into serious work in audio gear. Use Cardas quad eutectic and a good adjustable solder station. Hakko makes a great rig for $100 on Amazon. You can’t beat it At the price and will last a lifetime. Realize PCB and point to Point applications require a much different approach. (Temp) Also, those recapping x-overs, use a heat sink(2-4$) to protect those expensive new caps. Leads heat up quickly and most noobs aren’t quick with an iron. Less is more, both in time heating and solder used. Finally, remember that a shiny joint is needed. Re-due bad solders than and there. Don’t wait til they’re a problem. With what people spend on caps and wire, spring for good solder. Cardas is a real player in the metallurgy game for a long time, fortunately for us audio heads. ***no affiliation at all to Cardas. Usually I don’t post positive reviews. When it’s needed it’s needed.

Absolutely great solder, flows easy, good cleanup, sounds fantastic in my Bottlehead Crack. A clean precise solder for audio applications.

Melts like butter. Hardens quick. I dont see any flux residue. This stuff is awesome, and its made my job a lot easier!

By far the best electronic solder on the planet! I will never purchase anything but this solder for PCB boards! It’s makes the job not only easier but enjoyable. I would recommend it to anyone. When my roll starts to get low I will be purchasing another.

Expensive and really worth it!

I grew up in the 50s and 60s and took Electronics Shop in High School and did projects before that so Ive spent countless hours with a soldering gun or iron in my hands. Im used to old school solder and had some worries that newer stuff would be difficult. Its not. This solder performs extremely well. Some of that is possibly due to a decent soldering station, but even on a cheap throwaway gun it handles just fine.

My dad told me this is the best solder ever. You think you know more than my dad, dont buy it then...
