  1. What is the DL103's compliance? - see below
  2. How much does the DL103 weigh? - 8.5 g
  3. What is the recommended tracking force? - 2.5g

  The compliance of 5 x 10exp(-6) cm/dyne quoted for the Denon DL 130 on its internet site

  http://elec.denon.co.jp/japan/products_d.html

  is the Dynamic Compliance. My Data sheet for the DL 103 doesn't give the static compliance.

  To calculate the arm resonance you need to use the static compliance. The data sheet for the DL103s gives both static and dynamic compliance figures.

  Static. 25 x 10exp(-6) cm/dyne
  Dynamic 8 x 10exp(-6) cm/dyne

  The data sheets for other cartridges of mine also show an approximate 3 to 1 ratio, between static and dynamic compliance. So I would estimate that the static compliance for the DL103 is about 15 x10exp(-6) cm/dyne. This will give a much lower arm resonance frequency.

  Note also that the Denon DL103 is very underdamped which means it has a very sharp resonance peak - the cartridge can wobble violently at resonance frequency. You might like to try the optional fluid damper with the SME arm to tame this.

  I am considering the SME 3009-R, for a Thorens TD 160s, so I would be interested to read your findings.

  Regards,

  Brian.

  PS 1 x 10exp(-6) cm/dyne = 1 mm/N (a much better unit)

  Mel did answer 1-3 perfectly.

  Just a note concerning 4:

  I use the 103 with a 3009/SII. Although the arm is too light (9.5g) from a merely technical viewpoint it works very well. In any case the 3012/R will be better since it is a little heavier (12.5g). Any good arm between 10g and 25g should be fine.

  5 x 10 -6 cm/dyne

  8.5 gr.

  2.5 +/- 0.3 gr.

  Not me.

  This wonderful cartridge requires an arm that can control it, one designed for medium to heavy mass. In the alternative, an arm which is very sturdy can be made, more or less, compatable by using weights designed for the purpose between the cartridge and mount. I have used it both ways, initially with an Alphason, now with a VPI.
