To give a bit of background on CEntrance (as I know many of you have not heard of us), we are a design firm who has been helping other companies bring products to market for a decade now. In fact, our USB solution is licensed by Bel Canto, Lavry, Benchmark to name a few. We are a licensed 3rd party design house for Analog Devices, OxSemi, Texas Instruments, AKM, XMOS, and others. We really took a hard look and listen to all the components used in the DACmini especially the DAC which we chose an AKM part.
If you take a look at the DACmini link in my signature there is a link to the DACmini page. Take a look at features tab where we have a case study of all the lessons we have learned from working for other manufacturers for the past 11 years. This should give you an idea of why we made many of the decisions we did on DACmini.
@bcwang we may want to borrow some of that bat-like hearing to test some of our new products in the future
And as always please keep the questions coming!!!
