Just broke out my SR-4070 which had been in storage for some time. Driven by a KGSSHV, they sound quite different than my SR-007 2.9 which I normally use. But not necessarily worse. In fact I think they might actually have the more "truthful" presentation, though not as fun to listen to.
I notice that my headband fits different now. The elastic is more stretched out, probably because I used to always store them on the Stax stand with the plastic cover, so constant pressure on the elastic (which seems like a bad idea in retrospect). I know the regular Lambda models can easily swap out their headband when the elastic goes but does anyone know how I'd manage that for the 4070?
