A few weeks ago I purchased a Lisa 3 amplifier to replace my Ibasso D6. I use the amp as a "Transportable" setup at my office with DT770/250 and my Ipod classic with LOD. The problem is that now much of my music is hard to listen to. When I used my D6 amp everything sounded great and I had no problems. Now most of my music is very bright and gives me a headache. I am wondering if this is mainly due to having a poor source and the Lisa 3 is now just letting me hear it. When connected to my laptop using the D6 as a DAC the sound is much better and dosn't present any problems. I was thinking about purchasing a new source (HM-601) or buying the CLAS. However I am also considering purchasing a different set of headphones something that would not be so bright.
Has anyone else had the problem of upgrading to better gear and getting worse sound? Or is this just a case of no synergy between the Lisa and my DT770s?
