The AT1010 uses a chuck type attachment and it's very very secure. It makes solid contact between pins. It's the best arm I've owned (and about to get better) regardless of headshell.

Jamie, has just bought a Pioneer arm with a removable headshell and it's not come off his TT either, replacing a Zeta and an Alphasson. Both of those had been rewired too!

Its not the headshell being attached or one piece arm/headshell that matters. It's the damping properties, bearings and tonearm wire connections that matter. Get that right and your laughing. Soldered or pressure connection, hasn't made a blind bit of difference in my system. The arms limitations have been the biggest factor.

IMO.
