Denon DL-103 -- Was it a mistake?

I have been hearing that Denon 103s require very massive arms, have they changed the cartridge? In the 1980s when HiFi Choice was a serious magazine they conducted the most comprehensive arm and cartridge tests I am familiar with. At that time they estimated from their tests that the compliance was 13 in both lateral and vertical planes and recommended arms in the 6-16 gram range. I now see the 103s compliance listed at 5 in some sites, have they actually reduced the compliance that much? The cost in 1985 was 80 pounds in England, not far off what I paid this year for a new one. Are you using 2.5 grams tracking force? With the large footprint of the spherical stylus this tracking force will not damage the records and is quite necessary. I use that weight in my Scoutmaster arm which has about 7 grams mass and it is working quite well but took some time to break in. You can always add mass as Viridian suggests. I was a Supex dealer and used in the 1980s when I had high mass arms like the Lustre 801 and the Fidelity Research so I haven't used the Denon in a high mass arm. I would be patient until I had a hundred hours or so on it and if I was still unhappy add mass then. Turntables and arms take a while to optimize , take your time, you have a good cartridge.
