I doubt a low priced DAC will be an improvement over the Arcam. In fact a low cost DAC or a mismatched cable might introduce jitter that wasn't there with your current setup.
But what are you looking for? If you are looking to change the flavor of your system, then a tube DAC would do it, but it would be more like $400 (Jolida for example).
