Got an answer from Jim@ NiceHCK. A direct upgrade on the HK6. Hows about doubling the BAs to 12.. DZ12
Gonna start saving up for these...My rule of 3s apply here. 4 BAs for treble 4 BAs for mids and 4 for Bass? These could very well be end game.
This is using the same nozzle design I like a lot on the HK6 and the shell obviously looks bigger. The interesting thing about these. There is no reviews on them. But there are about 10 for the 14BA top of the line iems from NiceHCK. Price difference is not that different from 12BA to 14BA so I can see how people will be buying the 14BA earphone. But again Jim didn't say the 14BA was the upgrade to the HK6. He showed me these. With double the BAs in the house. I can see this being a nice upgrade on the HK6.
