How to configure Topping D90 DAC for BEST Performance

In this video I will show you how to get the absolute best performance out of your Topping D90. By default there are some settings that can hold back the performance. The first is Pre-amp mode where the up and down buttons will act as a digital volume control. For best performance it&recommended to disable this and put the D90 in what is called "pure DAC mode". Another performance benefit is to disable the bluetooth receiver if you plan on never using bluetooth. Also outputting to both XLR and RCA at the same time limits performance and it&recommended to output to only one at the same time. I will demonstrate all this on the video. There is a secret hidden settings menu to change some of these settings and you can access it by holding down the power button while switching the power supply switch on the back at the same time.
