I'm very happy with it, coming from Cambridge Audio Dacmagic 100/Topping L30. It has plenty of power for my DT990 250 Omh, not going over 1/2 of volume and the sound feels more exciting that on Dacmagic 100. Sound feels clean and spacious.
Ok with all the coupons, discounts etc, I've got it for 80$ ;) Thanks a lot! If I won't be happy then I will get DX3 Pro+. I currently own CA Dacmagic 100 and Topping L30 but it makes too many cables on my desk.
