Bob and Ray Throw a Stereo Spectacular is my all time favorite test disc, the one test that every change to the system must pass: by making The Song of the Volga Boatmen sound better.
The danger in making the bulk of your sonic judgments using only one record is that you never want to optimize your system for a single record, only to find out later that it now sounds better but others you play now sound worse.
Here is the story of how I made that mistake long ago (and apparently did not learn my lesson): In 2005, I fell into a exactly this kind of audiophile trap.
The Right Way
So the right way to go about testing and tweaking is to get all your hardest test records out and start playing them, making notes as you tweak and tune your system, setup, room and whatever else you can think of.
This may take a long time, but it is time well spent when you consider that, once you are done, all — or nearly all — of your records will sound better than they did before.

In my review of the 45 RPM Tillerman, I noted the following:
Recently I was able to borrow a copy of the new 45 cutting from a customer who had rather liked it. I would have never spent my own money to hear a record put out on the Analogue Productions label, a label that has an unmitigated string of failures to its name. But for free? Count me in!
The offer of the new 45 could not have been more fortuitous. I had just spent a number of weeks playing a White Hot pink label original UK pressing in an attempt to get our new playback studio sounding right.
We had a lot of problems.
We needed to work on electrical issues.
We needed to work on our room treatments.
We needed to work on speaker placement.
We Repeated Our Mistake
