Yes, analog stages of DACs definitely differ, and some are more susceptible to noise than others. But would that noise depend on the data format? This is where science and engineering comes in. Let's take the two most common "theories" (I'd rather call them "speculation") - 1) jitter is a major factor in the resulting sound, and jitter can be affected by the source and data format used, and 2) the source (and the data format used) is affecting the DAC through electrical noise conducted from the source to the DAC. The way the scientific method works is that you formulate tests, based on your theories, that can validate or invalidate your theory. In the case of jitter, DACs with ASRCs and fifo buffers should perform much better than DACs without them (albeit the ones with ASRCs might have other sound quality issues). Do we see a clear pattern of people preferring DACs with ASRCs and buffers? Do they do better in listening tests? In the case of electrical noise, do we find that systems using optical connections generally sound better than systems using electrical connections? I think the answer to both questions is "no". It is good to have an open mind, but that doesn't mean abandoning scientific thinking in favour of faith and dogma. "To try to judge the real from the false will always be hard.
