Hello Shoff -
I hope you enjoy your time with the DNA-500. It is a fine amplifier, and happens to be an extremely good match for your Aerial 10-T speakers. Don't worry too much about finding the lowest-possible output impedance preamp. You do need to keep an eye on this spec, and I suggest you stay below 800 Ohms for best matching. But once you are under that value you should be fine, so look for the preamp that otherwise best suits your sonic and feature requirements.
Best regards,
