Increase tonearm mass to match low compliance cart

Do not read too much into Denon's compliance number. If you do a search at Vinyl Asylum, there is a general concensus there that Denon's number is not particularly accurate and that the real compliance number is closer to 9cu. A member there has measured the reasonant frequency of his 103R in a 10.5g SME V to be just under 9 and many people feel that the Denon works well in many medium mass arms as well as those with higher mass.

Try it as it is and see how you make out. If you feel compelled with adding mass to your arm, I'd suggest using blu tak on top of the headshell and not adding more than about 3-4 grams to start off with.

Hi Binar

Your calculations are correct, but a DL103 compliance is higher than 5cu/dyne. A number of posters on the vinyl asylum had tested them and I believe found it to be around 12cy/dyne.

In short, it will work well with your RB.

If you are skeptical and want to add some weight, I suggest you use some blue tack.

Thanks, fellas.

Binar,

Hdm and Pauly are correct, and so is Dan_Ed. You'll get a noticeable, audible and enjoyable improvement by adding TWL's HIFI mod to your arm, especially with low-medium compliance cartridges like a 103R. I know. I've done it.

Here's the thread. It's well worth the read. TWL's mod does exactly what he described.
