I have been sitting here for the past three hours auditioning the GOS, which I received yesterday. I was expecting it to be good, but quality wise, not as good as the EWQL lib, nor as good as the basic VSL lib that shipped with K2. Boy, was I wrong. Better? No. But just as good. A bit different, but the quality is basically the same - what it's coming down to here is mostly EWQL strings, because of the different mic placements. But what I think I am going to wind up doing, is loading the F & S EWQL mics for ambience, and loading the GOS comprable samples for some things. I already keep the C EWQL mics up, and the other two down, and am finding that on some articulations, if i use the GOS samples as close mics in conjunction with the F & S EWQL mics instead of the EWQL C mics, I get an excellent result. Now, if GOS only had F & S mics....HINT HINT!!!
