What is better sound overall, the Topping D2 or the Topping D3?  How much better (for an audiophile) is getting the combination, Topping D30 and Topping A30?  Thanks.

Hi, I am sorry that i can't tell you exactly what the sound quality of them. Because the device will vary depending on the connected device. But according to the use of people to introduce these devices is still good.The two(A30+D30) are used together to ensure the purity of the sound quality. The audiophiles listened at the exhibition and gave this combination a full affirmation.Thank you!
