More specific information would help answering your question.Try yourself and decide which one you like as it depends on the devices you use.

Block cvr 100 amp, dali ikon2 mk2 speakers, play mp3s from my macbook that is connected wireless to my apple tv and optical cable from apple tv to my amp. I have an idea that usb direct from my mac to amp would give better quality..

Usually an external Dac (Block) should give the better result in sound in comparison to the soundcard of a computer if it is nothing special,so USB.But it´s easy to try yourself.

If you're just asking which kind of cable sounds better, the answer is that they will sound the same.

You can't really compare optical and USB cables, as there will always be other variables involved. USB is asynchronous, optical SPDIF isn't.

Given the choice, and assuming there's no impact in terms of cost or functionality, I'd go for USB because in most cases it will have measurably better performance.
