Can I ask one of you guys who have experience with Ultrasones (oqvist's PRO900?) how their sound signature compares to the German Maestros? I saw mentions of big soundstage and that they don't sound like closed cans. I'm thinking about trying Ultrasones and would like these characteristics.
They have indeed a large soundstage and a lot of detail.
On the other hand, the bass was utterly overwhelming, mids recessed and the highs piercing, metallic and sibilant. I never heard such a unbalanced and unpleasant sounding headphone.
I prefer my GMT250 anytime over the Pro900.
