Quote: Hey guys, I have just made some comparisons with Eximus DP-1 amplifier section and Burson's. I have used my Audio-gd NFB-9.2 as source for both them. As headphone, I have used my gf's Etymotic ER4S. The general feeling is that the Eximus is the better amplifier (we aren't even taking their two DAC sections into account, obviously, as I have bought the DP-1 as an high end source, primarily, while I was interested in the Burson to see how it fares as a headphone amplifier mainly). In general I see that: - the Burson amp has blurrier bass, and fatter, less neutral. Treble is also less refined. - the Eximus has the more transparent sound. - the Burson is more powerful, although offering less general quality. I will be making comparisons also for the Audio-gd 9.2 and the Eximus dac's. They are both good sources.
