I am recently new to this whole scene, and I finally got some decent entry level headphones (Superlux, HD 668B), and a decent entry level amp (Little Bear P-1, Hybrid 12AU7 amp). I found that with these two new additions I have noticed two huge jumps in audio quality, over my previous Sony cans...

So I just bought these off ebay because they were just too interesting to pass up, but I cannot find any information about them anywhere what-so-ever. Just looking for any input from anybody that may have ever seen, or heard, or know anything about these.   It says that they use three drivers...
