There were lots of test records available, from Decca, JVC, Ortofon and others that could be used for 'proper' measurements using instruments, plus a load of others that could be used by amateurs without measuring instruments, like the Shure Audio Obstacle Course and the New HiFi Sound LP and the HFN LP. Most of these, both 'technical' and 'amateur' were issued in the 1970s and early 1980S, at the heyday of LP. Since then, I don't know of any serious test LP, except the Ultimate Analogue Test LP, from 2006, which isn't at all bad, and can be used both with test equipment and by ear.What would be a quality setup that doesn't cost thousands of dollars and doesn't require frequent maintenance?
Are there test records used for measurements? If so, has anyone done measurements? With the so many variable elements in the chain, this would have to be quite an elaborate experimental setup.
The problem with all test LPs is that some, like the HiFiNews LP offer very poor accuracy when using instruments, and the classic test LPs like the Decca are now likely to be worn out, unless you can find one unplayed, as they have a limited life.
Getting LP playback right isn't easy, it's only marginally easier than tape!
