@ozzy62 Looking at it again, I suspect that the compliance listed for the Denon is a 100hz measurement (often used by Japanese cartridge makers). The chart on vinylengine uses the standard 10hz. So if the Denon was measured at 100hz, the basic conversion to 10 hz would be in the range of 1.5-2 times the 100hz compliance**. Even with this conversion, a compliance of 7.5-10 would still put the Denon out of the optimal range (but a bit closer) for the Rega tonearm. The Denon has a very low compliance, and therefore will be a better match with slightly heavier tonearm.
**Note that I took this general rule from a discussion on Vinylengine. There are more precise mathematical ways of doing the conversion.
