I do feel like the Tungsram's calm the HD600 down a bit, which leads to longer listening sessions. That being said, the SW51+ with the stock tubes and HD600 is a head-bobbing machine.
Funny you should say that. I've always treated synergy as balancing out components...brighter amp for a 650, etc. Lately, though, I've been going the other way and leaning into a headphone's traits like you say. The 600s are currently tied to my "brighter" amp and the 650s with the darker.
