Jos Cenens from Belgium has upgraded his NAD C552 with aluminium sub-platter and dual pulley. Here's his comments and upgraded system:

Dear Michael,  Included a picture of my upgraded NAD C552. The upgrades went fine: the pulley installed without a problem, the sub-platter was indeed very tight to get in as the air under the shaft could not get out easily, it took a few minutes before the platter was in place (I turned it around and gently pushed on the top spindle). The 2 silicone belts were also quite easy to put in place thanks to your instructions.  I now had a good week of listening and I do hear an improvement. The music sounds better, more steady, the details present on the record are easier to hear (almost in all records that I put on). I am all in all quite pleased with these improvements. As you can see on the picture I recently installed a new element (Ortofon 2M Blue) and that gave a boost to the turntable. Your pulley, aluminum sub platter and dual belts further improved the turntable and I conclude that the investment in the 2M Blue element is supported by your material.  Regards,  Jos Cenens  Linden Belgium

Thanks, Jos!

Paul's upgraded NAD533

Paul of New York, who owns a number of newer Thorens automatic turntables, bought a manual value-for-money NAD533 deck to tweak. No hassle, NAD 533 shares the same benefits as Rega decks when comes to tweaking.  So he gladly begins with stainless steel pulley, aluminium sub-platter, stainless steel underslung counterweight, acrylic platter and top alloy bracing.

Paul is a fast worker and comments and pictures are sent in real quick! Thanks Paul!

Here are the pictures and comments. Enjoy!

Micheal,  Find the attached before and after photos, table sounds great, everything is much more defined and open. I have intermediate photos as well if you need any, just let me know, thanks again, Paul Pulley,sub-platter,counterweight and top bracing upgrades Acrylic Platter upgrade

Thanks Paul.

When it comes to Rega upgrades, NAD 555i enjoys the same benefits of sonic improvements too.

Johan Wallstrom' s feedback on the upgrades :

The sub-platter and acrylic platter runs smooth and I have already noticed a reduction in background noise and clearer sound. Bravo! I'll get back to you when I have listened some more......   My system: Naim uniti + Naim StageLine phonostage, Harbeth HL-P3ES-2 speakers, NAD C55i TT Johan Wallström

Thanks, Johan.
