when you hear various comments like that, you do think twice. If someone with experience can't make it sound good, I definitely can't.
There's a converse to this also - sometimes it takes experience to make something sound bad. re-peat's (similarly savage) critique of SStS, for instance, was helpful. He provides a penetrating insight into the limitations of library. But it took me quite a bit of effort to even reproduce (some of) them. Wheres my own experience is that on the whole it's wonderful $200 library. To be clear, there is no accusation of bad faith, here. Library makers generally don't go out of their way to foreground the spaces in which the library sounds truly bad, so more experienced people able to immediately hone in on these no-go zones in the palette of a library are genuinely helpful.
So in this sense, was my own failure to make the library sound bad a consequence of my the limitations of skill own level and my (by comparison) 5-year old brain? Sure, you can put it like that if you like if you like. Why not.
And would I like to shift my main string library to something more deeply sampled (and more expensive) within, hopefully a couple of year if all goes well? Absolutely. But for now, I'm loving the sounds I can make with SStS, and am over the moon to be able to get into this kind of aesthetic space for $200. (And I'm also glad I bought it before I read the negative death spiral of negative reviews, which don't seem to be terribly relevant to my own experience).
So I'm grateful to have access to this level of (even rather savage) professional critique that the above represents. My only point is that, for many of us here, it really needs to be contextualized to be helpful.
That's say, you're probably right about the SStW oboe though - certainly for exposed lyrical passages, it's clearly not sampled to the level of the (immensely beautiful) oboe in SSW, or OTWW exp B. Of course the oboe in the latter alone in effect costs almost as much at the 13 instruments in SStW. So for most of us, price is a relevant bit of context.
