I do use the MicroZOTL with a Pass XA25 on a pair of Dynaudio Heritage Specials. I think it is a great combination - very musical, dynamic, engaging. I have not heard the PrimaLuna to compare.
Also very glad LTA worked things out with @audioman58. Customer experience counts for so much and LTA has a very solid reputation at this point. They have always been very responsive when I have reached out.
