Joel,
Incorrect. Esoteric does OEM and use the Pioneer Transport and associated DSP servo circuitry in the DV-50 and DV-50S models. This was most likely done because of a price point to meet and for production. This is same transport mechanism that is in the cheapy Pioneer DV-563, 578, pioneer dv-45a, dv-59avi, muse 11 etc..
There is nothing wrong with this transport mechanism. It is ROCK SOLID! and reads every disc, every time, right gmood1??
Esoteric does utilize a different clamping system for the disc, which should improve vibrational characteristics.
The VRDS transports/circuitry costs WAY much more to build and implement, since this is done at TEAC and not mass produced like with the Pioneer OEM models, and then TEAC upsells the VRDS to Wadia who then put them into their machines (which are not cheap! we are talking about a second mortgage here!) . This has to be one of the reasons they have a $13K msrp on the higher models.
