@ All , thank you for your impressions about this two flag ships. I am realy like my Abyss and I also totaly fine with the way this HP will sit on my head. But on some music, I think the mid's and Treble's could be clearer and better. I had for one month the UTOPIA and yes, the mids and trebel on this HP was absolut first class. BUT ! all the music did only played infront of my head, no room and air, no deep and stage. It was like a two dimennsion music. When I then switch over to the ABYSS, WOW what a stage and every thing was in three dimmensions. There is no question for me, The Abyss is like a pair of Loudspeakers and this is the reason for me, why the Abyss will allways stay in my Home. The UTOPIA did find a new owner.
But now I searching for a HP which will bring me on Voice Music and small Jazz trios the mids and treble which I don't have so good on my Abyss.
The Egoista 845 will have enough power, but I am a little scary that I will drive the LCD4 to death with my heavy Pipe Organ Music. I heard that Audeze had in the past a lot of trouble with there drivers. Perhaps every thing is now fine ?
Thank again to all for your help !
Ralf
