I have compared them side by side with a variety of headphones and really found the Taurus better. More detail, deeper soundstage. Mjolnir is somewhat flatter sounding. Mjolnir is a good amp, but you get a better amp in Taurus. Even the HE6 sounds better at Taurus, even if Mjolnir has higher wattage rated in the specs.
I have noissues with noise or hum on the leven ezcept when using high impedance phones. Low impedance phones, even the 110dB Sennheiser Momerntum are quiet. I tried it with the Klipsch RF8 rated at 98dB @ 2.83V / 1m and had no hum there either. I think the hum from the Leben varies a lot with mains and tubes, since others report otherwise. But I think that is a minority. .
^ I just do not think people should believe that you need a big speaker amp to get the he6 sound great. I was wondering if you had any specific experience with speaker amps being significantly better than the Taurus, or wether you were just assuming Taurus is a lesser amp following the general "truth" of this thread. That's all
