I had / have both. I am returning the DX5 and keeping the EX5. It provided better support for my low impedence planar headphones than the DX5. I had more headroom for power on the EX5 than DX5. I am also returning the DX3Pro Plus (same amp as the DX5) for the same reason. I feel the EX5 is a great value compared to the DX5.Currently deciding on whether to purchase the DX5 or the EX5. From my understanding, both share a rather similar feature set with only minor, likely inaudible differences in technical performance. Can someone give me any reason to grab the DX5 if it costs $85 more? Don't want to regret grabbing an EX5 if the DX5 is better, but I can't seem to find a meaningful distinction. Thanks!
