Audio gd just look at the forums digital is supposed to run cool not gd ,they run hot and horrible distortion specs look at audio science forums and plenty other board failures thats why I bought a Denafrips runs cool and exceptional low distortion .
DAC upgrade suggestion
I am currently using a Audio-gd nfb 3.1. The information below. I bought a Topping DX7 pro based on the good data in audio science review.com. When I first use it, I can hear the difference immediately. It is more dynamic, bass is more punchy, sound clearer. It sounds great. But after listening for a longer time, I feel a bit fatigued. I can compensate it a bit by switching the tubes in my amp. Then, I need to return the DX7 because the Bluetooth doesn’t work. I plug back in the Audio-gd, and i can confirm it is not fatiguing. It is less dynamic, but also smooth. Now, I am confused on what I should upgrade. Several Audio-gd DACs are reviewed by AudioScienceReview.com and the data is very bad, LoL. I know the bad data doesn’t mean it sound bad, but should I avoid DACs with good data? How should I pick my next DAC? It seems R2R DACs maybe a good choice for me since many people says the sound is more analog-like.
