I also choose between ESS and AKM4497.MQA support will be highly appreciated.
Will this be first lunch on crowdfunding first?
But ESS support（hardware）MQA rendering，which makes me very excited
There are many ways to achieve more detailed volume adjustments, such as designing variable gain and using high-performance electronic volume chips.Know the relay based volume control out of my R28 or the NFB 10.33.
OK. the space usage of the AGD's belongs to the power stage and on the R28 to the R2R dac.
Don't know another one till now. Thanks for the hint.
For each gain, there is a different volume curve corresponding with it. Just as our K5pro， which has 3 level gain and NJW1195 for fine volume adjust.
