Are VSTs within a DAW subject to any distortion while their digital audio is rendered in any way?

I know some information of Analog-to-Digital Conversion and while still learning of such, I am also now wondering if there are any distortion matters in a digital-only realm.

I'm doing a few tests to see what sounds better. In your opinion which do you like better fidelity wise.
It's not an exact test as it's not the same performance, just looking for opinions on which sounds better.

In music electronics, this term indicates how faithful a reproduced signal is to the original. For example, a "high-fidelity" signal would be a very true representation of the original sound.

after twisting and contorting my spine into all sorts of positions rewiring hookups behind my rack, I think it's time to invest in a patchbay.

For those who do not know, I have been involved with High Fidelity sound and equipment since 1972. Our art reflects what designers put into their perspective components for music reproduction of the highest regard. This is why I consider our art serious business.

I figured out that it was not necessarally the equipment, but the recording arts had to evolve.
