Kind of stuck. Fulla 3 + HD6XX is underwhelming to me right now. I owned HD650 years ago with a ChiFi amp and seemed to like them better, but my memory could be wrong. I can’t help but feel that my current setup sounds way too congested. Would a Magni 3+ fix this? Mods? If mods, how much % of an increase, realistically? I used to own modded HE400s and drove them from a vintage receiver and ADORED them. But can’t exactly afford that setup again and those were sold long ago. I just miss the slam and physicality they offered, something that is definitely missing with the HD6XX. Sure they were bright, and 45 minutes was about all I could take, but they were fun and engaging. Anyone have some solid advice on how to proceed? The tone of the HD6XX is perfect, I just miss the tactically of instruments that the HE400 brought (hits of the drums, plucks of guitar strings, etc).
