I know enchanting is insanely powerful as it is. However, I'm forcing myself to not use any kind of crafting on my current character, to make the game more interesting. And it's working really fine for now. The excitement of looting a chest and finding better items is great, as well as taking a look at merchants every few days to see if new nice items have arrived..

So, my question is:
Can I eventually find random items as good as the items I could enchant? For example, I know with the right perks someone can easily craft a weapon with +25 fire damage. Is this kind of item also available as loot? And can I also find random items with two enchantments (like the ones you can craft with master enchanting)?

Earlier I found a Heavy Armor helmet with +40% bow damage, which is maximum you can get with all the perks in Enchanting tree.

edit: Some items also have multiple enchants, but I think this only applies to quest rewards and artifacts, not randomly generated items you usually find through exploration.

This.
