New Jays Audio flagship cd transport

REF: Jay's Audio  CDt-2 Mk3 vrs CDT-3 Mk3    Can anyone tell me please, other than the price difference, why I should spend double the price, and what you get for the money, most likely my last CD transport, mirrored with a Meitner MA 1 DAC  Currently running a Audio lab 6000CDT.

Robert TN   Thanks    Ps was also considering a CEC tL5 and a Project RS2T 

To answer the above, One of the most important considerations of purchase ( CDT 3 Mk 3, is your business affiliation with the above unit. So far everything I've researched of your business is stellar.  Service and repair is paramount to me, as I'm sure as it is to others. In the event I do order one, should it be through TEK specialists? Thanks Robert TN
