I have to say I am thrilled with the listener. Immediately after the initial setup, said the sound to me. I hear now about 30-40 minutes of music and hear excited. Of course it is not meaningful enough, but after the first audio impressions I can say, the headphones remain. In the SACD, the life of Schiller, thrilled the T90 with an extremely gentle and at the same time velvety voice reproduction. That is my opinion achieved by the centers seem somewhat damped. That is not meant negatively, but on the contrary. This in turn produces an unparalleled reproduction of the heights that seem airy and clear. The bass is rather designed my estimation on quality rather than quantity, which makes also a positive effect. An overall very high quality appearance when it comes to music playback. I must say, I hear on the headphone output of my Denon DCD 1500 AE, which amplifies the bass something. The more likely it is that a high-quality headphone amplifier the last percent potential could be exploited is. My overall impression is that the listener is an absolute fine draftsman. I also have the opportunity to compare the T90 with the AKG K701, which is of course subjective, but the K701 is the T90 in any way equal. The vote is clearly a very different, but I feel like the T90 is to provide a stage above, but this is a matter of taste. For comfort I can not really say what, because only less than an hour heard it, but so far can not find anything negative. So that's times .. with my first impressions
