How easily can you distinguish between different DACs?

I have found that DAC useage is just another overkill like cables and wires. It’s about quenching your listener satisfaction and it’s about self-control. Can you be satisfied? And… save your money.

It’s about quenching your listener satisfaction and it’s about self-control you only live once. 

Compair them on a very revealing system.  In  some systems, you may not notice and significant differences.

So the difference would be that the cornering somehow just feels better in the Ferrari and so is a more enjoyable experience that justifies the cost.

Really? You think that's the only thing setting a Ferrari and Corolla apart? I don't have the means to own a Ferrari but I have driven one on a track every time I get a chance to go to Vegas. The acceleration, the way the steering wheel communicates the road to the driver, the way it sounds when gathering speed, the braking ability, and the overall exhilarating feeling you get every time you get behind the wheel ... there's nothing even remotely comparable to a Corolla.  All these are factors (or nuances) that collectively contribute to making the whole greater than the sum of the parts. The same holds true for higher end DACs as well. You simply cannot isolate a few measurements or one or two aspects of performance. You have to evaluate them as a complete package.
