I wonder which are the reasons of this exceptional interest
Is a kit of this preamp available ? (this is a joke :eek:)
No seriously, is this unit a masterpiece of audio technology ?
By the way the 3D is almost impossible to follow because not all the comments seem to be pertinent i think.
Thanks a lot and kind regards,
gino
