im also a noob on making cable, but i know from doing some research that for the
connectors to the 650 should be the cardas ones(its higher quality than original jacks)

the headphone jack is a preference of what you want(really doesn't matter)
the cable is based on sound signature preference, but i hear any cable is better than the stock one
if u want to a more balanced sound the silver dragon i guess

for solder i heard that the the cardas one is good

Q.) I'd like to know what makes Cardas solder better than all other solders for audio work. What advantage does Cardas solder have over other eutectic solders that makes it worth its much higher price? On the one hand, there is Jennifer of Jena Labs claiming that no other solder should ever be used, and on the other hand there are people in DIY chat rooms that say these exotic audiophile solders are a waste of money and no better than products like Kester. Thanks for your response. - Michael
A.) Hi Michael. The vast majority of solders in the world are slurries or mixtures such as 60/40 tin lead solder. They go through a slurry stage as they solidify wherein one component solidifies first and then another. The result is a solder connection rather than a joint. Eutectic solders such as Kesters Ultra pure Tin/lead Silver are in fact excellent because they solidify at a temperature lower than any of the component parts thus they form a solder joint rather than a connection - the key here is the eutectic formula which must be very precise - the solders are obviously different in that they set up with a mirror finish rather than a dull finish, the reason they do this is because they solidify as a unit. The week link in the solders is contamination - the molten solder easily dissolves other metals, this is no problem if you are soldering to a metal that is part of the eutectic mixture (such as tin or lead) you will get contiguous flow right in to the joint (easy to see) but if you solder to a dissimilar metal (such as copper or silver) you will see an obvious dulling at the connection where the eutectic formula fails and and the continuous joint becomes a connection. Cardas Quad Eutectic is tin, lead silver, copper, eutectic. The results are obvious. Most highend products use this solder and other cable manufactures have been using it for over a decade - to them it represents good sound and absolute reliability. - George

looking forward to steps i want to make one soon too, but have no experience as well
Hope i helped a little bit.
