i have a reason for asking this question.
it would be useful to have some set of measurements that could assist in discriminating potentially poor sounding, from potentially good sounding components, as it is impossible to audition many components.
there is always the possibility of missing out on a decent piece of equipment because it is inaccessible. as well, one may waste ones time auditioning a component that does not match well with the other components of a stereo system.
it would seem that there is no algorithm available to assist in the process of increasing the probability of eliminating "unwanted" components and ferreting out those which have promise.
