I agree with evaluating on more than one level. Sound quality is a clear issue of its own. Accuracy is easy enough to evaluate, if one has a score. Musicality is more complex, as there will be interpretative issues where views will differ. I also agree with Richard's comment that anyone producing an assessment of a recording should provide reasons behind their decision, rather than just a simple numerical ranking. I think if we are going to trust experienced members to make decisions regarding quality of recordings, we should also trust in their judgement as to whether they feel competent to assess the music in question, rather than appointing X to do composer Y etc.
