Now you're asking! This was two years ago. I don't think we used the Arcam as a transport. I think we used Robbo's DPA transport. I'm not sure. Perhaps one of the others can remember? The Arcam had more warmth. It also projected vocals more into the room so that they were clearer and easier to listen to. The DAC20 sounded a bit thin, a bit grey and a bit shut in by comparison. The Arcam had a smoother top end too. Basically the Arcam was just more involving and enjoyable to listen to. There were a few dropped jaws at that bake-off. They weren't expecting much of the Arcam. They got a surprise ;)
