I too am happy to go along with recordings that other have. KBO is a no-brainer, the Simon is also good. No reason not to use more than one recording; including the Fagen. Re the Fagen, and some general comments applicable to all (IMO):
While it may seem anathema to use a digital recording (LP) for an experiment such as this, there is no reason not too when we consider that what we are looking at is the ability of the arm/cart setup to retrieve the info in the grooves for us to compare. Obviously, the digital recording should be an exceptional one; and wether we like to admit or not, there
are some. I like the idea of analyzing and comparing tonal qualities, but for that to be meaningful we have to be very specific and use either personal experiences of live music attendance, and/or comparisons to other LP's; in order to establish a meaningful benchmark. I don't think that comments about "the voice sounds a little bright in the upper range" will suffice. Brightness to one listener is clarity to another; unless we can also say "on this other LP XYZ, I heard a similar effect (at a specific point on the rec)". Then, we can establish some sort of pattern that will be meaningful. This could be a very rewarding experiment.
