Dweinstein, I have heard the VAC Statement 450 (driving some large Raidho floorstanders) and thought it sounded lousy, as did a lot of other people who heard the system. (It was the Sound By Singer room at the New York Audio Show.) And I have owned a VAC Phi 200 and thought it sounded good, but in the end was overrated/overpriced in my book. I like Pass Labs better. That does not mean that Pass Labs is objectively better than VAC. It means I like how Pass Labs sounds better than how VAC sounds in my system.
System matching is a make or break proposition -- you can throw together some very expensive components and they will not sound good together -- for example, if their output/input impedances are mismatched. With digital, the transport itself has a big effect on how a DAC sounds. The Perfect Wave DAC, for example, is not particularly impressive from the USB or S/PDIF inputs, and sounds much better when matched with the Perfect Wave Transport connected via HDMI/I2S.
I don't think anyone is going to contest your red herring statement that there must be objective differences in the sound quality and measured performance of various components. That is why John Atkinson spends so much time measuring performance objectively. What you are refusing to admit is that some components -- even very high-end ones -- sometimes do not sound good together in a system, and that sometimes, synergies between components make the whole greater than the sum of the parts. When you refuse to acknowledge the possibility of synergies in your system and declare that the Weiss is objectively superior to other DACs, in contradiction to others who have had the opposite experience, you sound like a religious zealot. If you love the Weiss DAC, great, we get it, but stop using reductionist arguments to dismiss everyone else here.
