Review: TNT-Audio – Bronze knife edge bearing

Do I recommend the bronze bearing ? Yes!

When used with the bronze bearing, the SME 3009R sticks up to the old war horse SME3009-2 of the sixties from musicality, better said flow and naturalness. Until now, it was a decision of heart for Garrard or Verdier owners: do I take the old SME 3012/2 which sounds so musical, or the new SME3012RM which sounds cleaner, but also “cold”. Most folks, who know the differences opt for the old tonearm when they have the opportunity to get one in good condition. Do I recommend the bronze bearing ? Yes! Owners of a SME3009R with plastic knife edge bearing, who always thought of upgrading to metal knife edge bearing, they now get an option, which is both cheaper (about 30% less) and sonically more rewarding. But the bearing upgrade is also interesting for owners of the SME3009RM with steel knife edge bearings, as the sonic benefits are way beyond that which you can buy for the same investment in cartridges.
