I'm wondering if the MK IV is a big improvement over the MK III and if it's worth the extra money. I'm going to use it with my Sennheiser HD600 and an Audinst HUD-MX1 as a DAC.
I'm curious about this as well. And between the III, IV, and V, particularly.
I think the MK V is solid state.
Yes, and I'd love to hear a comparison between them and the tubed units.
Yupp. Nothing so far :(
