The article in your link refers specifically to sausage-making, which is different from dry aging, so I'm not sure if you are confusing the two. Dry aging is not so complicated. If you want a salted meat, you can use dry salt or a brine, but you have to watch the weight as the meat gives up its moisture. You can find good basic instructions for violino de capra, which is a salted leg of goat. If you use beef for this technique, you will be making bresaeola, for which you can also find good online instructions.
I make aged, uncured, unsalted beef - not high meat - all the time because it is easiest to buy meat in bulk and store it for a while (without freezing). The sour flavor in the meat is very subtle, not at all objectionable.
