The 270C is the budget version, and fitted to trillions of mid 70s and 80s decks from technics. The 207 and 206 were better still, but the 205 was the totl version. The mk3 and mk4 are the ones to get, particularly mk4 that were specced to 60KHz -3dB. They had a proprietry damping system that degrades with age, so none of the original styli will work, but they had unbelievably low mass cantilevers and suspensions. I managed to find an unopened 205 mk2, the low output model. The rationale for Low Z (inductance) means it is load insensitive, so even a 500pF load will push the resonance way above audible threshold, so the FR is unaffected by the phono amp, the flip side of course is the low output, but my ifi phono should be able to manage a 2mV output.
FWIW, I prefer the sound of the 270C over a VM95ML. Ok latter has a smoother top end, but the technics has a punch and excitement that the AT cannot match that I find thrilling to listen to, I'd love to try it with the Jico SAS stylus, as that would improve it even further. However, the prices of thr Jicos is prohibitive for both carts, so I will indulge the 205 with that.
