How can we quantify cartridge performance?
When it comes to upgrading an arm, we want to know the return on investment. One method of quantifying improvement is to look at the pricing of cartridges. Trials show that your cartridge performance can be increased to the level of one costing up to 70 times as much – the tonearm being the only difference. This claim is staggering but backed by a wealth of evidence.
For example, 25 years ago, when all serious audio systems were vinyl based, magazines went to great lengths establishing system hierarchy. One test took a cheap £20 AT95E cartridge, verses an expensive £500 cartridge. The only difference being the cheaper cartridge residing in a better tonearm. With utter astonishment, the £20 cartridge sounded significantly better than the £500 one! This translates to the cartridge performing at over 25 times it's value!
Another example of hierarchy is related by a German dealer hosting an evening for 40 clients. He compared a cheap £100 Denon 103 cartridge with a well respected £2500 cartridge. Again, the only difference being the cheaper cartridge in a better tonearm. Sure enough, the cheaper cartridge won by a jaw dropping extent.
It's worth mentioning that this wasn't a poor arm in the ring with a good arm. Rather it was the highly respected Origin Live Silver arm against the Conqueror tonearm - much higher in the range. For perspective, the lesser Silver arm, was reviewed as “probably the best arm in the world”, when it first entered the market in 2002. We are looking here at an extraordinarily good arm, versus an absolutely top flight arm. Furthermore, the “best arm” statement on the Silver (£600 at the time) was no wild statement made by a newbie reviewer, but a magazine editor with years of experience of SMEVs, Linn Ekos, Naim Aros, tri-planar, Grahams and a host of other high end arms.
