No, i did not take K1000, it's so not as portable as mysphere 3.2. As the review of Primavera said it can offer huge soundstage and can drive most of the flagship headphones well, so i decided to try. And the worker there turned to the right impedance on Primavera, and i also tried even the higher impendance option, it did not help.
It's not about the power. It's about output coupling and the Pimavera is neither an OTL tube nor a solid state amp. The higher impedance is also not going to help if the matching is poor - with the Primavera, optimal results should occur with the Mysphere 3.2 and not 3.1.
