I had a pair of Burson’s at one time with another dac. The Dexa op-amps to me have more detail and transparency (highs are more extended) and a neutral sound all-round. Burson’s has a very nice full body sound a little to the warm side. The reason for the change, I replaced some output caps that made everything more detailed so it got me thinking about the Burson’s sound, they might be a better match now.
