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
We initially thought the room was doing everything right, because our go-to setup disc, Bob and Ray, sounded super spacious and clear, bigger and more lively than we’d ever heard it. That’s what a 12 foot high ceiling can do for a large group of musicians playing live in a huge studio, in 1959, on an all tube chain Living Stereo recording. The sound just soared.
But Tea for the Tillerman wasn’t sounding right, and if Tea for the Tillerman isn’t sounding right, we knew we had a very big problem on our hands, one that we had no choice but to solve. Which we did, with the first track on side two.
Some stereos play some kinds of records well and others not so well. Our stereo has to play every kind of record well because we sell every kind of record there is. You name the kind of music, there’s a good chance we sell it. And charge a lot of money for it if it’s any good at all.
And if we offer it for sale, we had to have played it and been impressed by the sound, because no record makes it to our site without having been auditioned and found to have at least very good sound. (Non-audiophile pressings with sound that does not meet our standards can be found here.)
Here are about 30 very tough test records you may find of value when working on your system.
Most of them are well-known titles that should be part of any audiophile’s collection. (The problem of course is that most audiophiles have less-than-optimal pressings of these titles, making testing with them a great deal more difficult than it would be for those of you out there with Hot Stamper pressings. If you are an audiophile who wishes to remedy that situation, we are, unsurprisingly, happy to help.)
