Yes, I have had two unipivot arms prior to the SME (back in the 1980s). First an Audiocraft then a longer Ultracraft. Good arms but not great arms. One had to dial in the correct amount of damping oil in the trough to use them. I have heard good sound from Graham unipivot arms at shows on ultra expensive tables such as the TechDas. I thought my next arm would be a Tri-Planar or a Thales, but the SME sounds excellent and is still being made and sold with a new SME table.
