So cool! Great feedback on this neat little amp! I haven’t pulled the trigger yet, but have corresponded with King. He only had a couple of KA 101’s left and told me a KA101 Pro version is coming out with a little transformer magic to be even quieter with headphones. The price goes up to 7300 hkd with free shipping. I’m starting over with a budget system and haven’t figured out my speakers yet, so I plan on getting that part handled first. Leaning towards Heresy III’s. Ironically, just cane across a nice Scott 299a so I’m conflicted. Although, I might just be sentimental for that piece. Is the KingKo a big step ahead of the Scott in performance? You have some great gear!
