yes Harbeth's 30.2XD's and The superHL5plus XDs tried and sold
they were very nice, I have some mild criticisms better suited to a harbeth discussion, let's just say not my cup of tea
those JA look very nice
the Ascend's pricepoint allows me to try and buy regardless as a stop gap, custom seas driver, raal ribbon, and Klippel measurements, appears to be a level of actual R&D and published measurements beyond alot of the smaller independant companies
