Playpen, The nanomounts are placed (ie. glued) onto the cartridge and then the cartridge is attached to the tonearm. The triple points are on the cart with the single point touching the tonearm (you must not overtighten the cart to the tonearm). This is just like the system you currently use to drain vibration from your Rega's plinth only in miniature. With the tonearm you place the nanomounts between the base and the arm mounting board. This is not an easy process but I felt it improved the sound clearity (ie. reduced resonance)on my Clearaudio Champion Level Two and Unify Tonearm/ Ortofon 2M Black.
If you like your present rig and plan to stay with the tonearm I believe the nanomount system is worth it. I've tried tweaks from setup guru's over the years and I have had the best results from Pierre Sprey of Mapleshade. He has many no cost tweaks on the website and some that you can purchase. I believe that before you spend alot of money on a new cart you should try this solution and it has a money back guarantee. Mapleshaderecords.com
