The references I use are LPs that I recorded. I have the master tapes and know what they sound like. I've used a number of arms at home and at shows; the one that consistently gets everything right is the Triplanar.
It has the hardest metal bearings available on any tonearm.
One thing nice about the Triplanar is you have some ability to adjust the effective mass of the arm. This allow you to use a wider range of cartridges. It is the ability of the arm to track the cartridge correctly that is the most important! VTA can be adjusted on-the-fly. Azimuth is adjustable. The arm bearing is in the plane of the LP (provides for more consistent tracking pressure with warp or bass modulation). The arm tube is damped so it does not talk back to the cartridge.
I have found the SME12" to be excellent as well as the Kuzma 4-point.
