I've owned transrotor belt drive, 401, Colaro 2010 and Lenco ptp, all sounded very much the same, I've never heard a standard lenco but from what I've read the lenco needs a lot of money thrown at it to equal a 401, I threw a lot of money at my lenco right off and it was as good as the 401. Collaro was very good but speed change was dodgy.
Now I have Denon DP80 and its better than the idlers, has the same bass, rhythm and pace and also wonderful detail retrieval. The DP80 is a different animal to other Denon dd that look the same but the DP80 has a three phase motor.
