Still, you might be wondering why I refuse to ‘name and shame’ specific LPs. That’s because the ES-001 exposed a dilemma which will drive some of you crazy – that of the deviation between two or more copies of the same LP and pressing. In the past I’ve purchased a few ‘identical’ LPs precisely for A/B’ing turntables and cartridges but some turned out not to be so identical after all. I won’t name them because my pressings might differ from yours, and this exercise is, after all, about inconsistency in manufacturing.

I can see some of you buying an ES-001, taking it to the record store and checking the copies in stock to secure the best – least eccentric – pressing. So the ES-001 will also be a test of LP vendor patience!
