I wouldn’t change the rubber mat until you have a cartridge that works fine for you. The reviews means nothing for me, the quality of SAEC SS-300 is better than anything else on earth, especislly the overpriced new toys. If you are looking for new stuff then Boston Audio Mat 2 is another option.
Denon DL-103 is the worst choise for your tonearm, it’s been said so many times here, for this low compliance heavy monster you need at least Jelco tonearm.
Your tonearm is for mid compliance MM cartridges or mid compliance MC.
Technics own vintage MM cartridges works fine with this tonearm, headshell integrated versions like epc-100c mk3 or 205c mk4. If you want warmer carts try MF (moving flux) Glanz MF31 - 51 - 71 and Astatic MF100 - 200 cartridges, they are very good too. Garrott P77 is great, Grace F9-U and F-9F are amazing. Pioneer PC-1000 mk2 is outstanding. Those cartridges are better than more expensive MCs and i have tested them all on sl1210mk2 in the headphones before switched to my reference tonearms and turntables.
Those Denons are just cheap and easy to buy new, many people use them for this reason. It’s not so easy to find top vintage MM cartridges, but when you got them in perfect condition you don’t need an MC, because there is nothing to lose if you load your MM at 100k ohms instead of standard 47k.
