sg: Not quite - there are a couple of technical differences. For example, the arm of the TD104/105 has anti-skating via spring, the arm of the TD110/115 via magnet. And the subchassis design also is different - however, iirc, there only were significant differences in rumble & noise, when measured with a coupler instead of a test record. Both the TD104/105 and the TD110/115 probably could be regarded as sleepers, that often are overlooked, though...

P.S.: Almost forgot to mention that the TD115 only does auto-lift & -stop, while the TD105 auto-returns as well.
