What external DAC to improve the Ultra?

So, you've been lucky enough to get some help performing the level matched blind test?

Yes, my son, who has young ears, helped me

Hello, I respect your opinion but I disagree.
I don't know how you connected the Ultra to the E70 Velvet.
I have it via USB, and the DAC is connected to the amplifier with some good Mogami XLR cables, and the difference compared to connecting the Ultra directly to the amplifier with a good RCA cable is substantial, I would say almost overwhelming.

Well, maybe I was exaggerating before, we've been testing again, with the difficulty of matching levels and the difference isn't that big. I simply hear more clarity by connecting the Ultra via USB to the Topping E70 Velvet and then to the amplifier using XLR Mogami Neglex 2549 and ViaBlue connectors. The other option, using the Ultra's own DAC with Wires4music's Horus MK2 RCA cable to the Audia Flight FL Three S amplifier, is also excellent and sounds very well.
