OP- it's impossible even if every component is a known quantity to others (and how many have that exact combination of components) to assess what you are hearing without being in your room. That's the point about set up. It costs almost nothing but is critical to extracting the most from whatever system you've put together. That's why I mentioned Jim Smith (please refrain from shill assertions); he does have a book about set up but that's the key.
The high end folks often do this as part of a service when you spend the moola- whether they are any good is a question but you take my point, not to be contentious? It's gotta be evaluated in the room. What does it sound like? Are you in a town, vill, city with a fair amount of audio commerce? There will usually be some knowledgeable people, although I tend to avoid gurus. :)
