Cheers for replies everyone. I have been without headphones for more than a year. Maybe, I had just become too accustomed to the feel of the slam from the speakers. I plugged in the HD800S around 1pm, it's almost 7pm now and they are finally back in the box. The only time I took them off was when my partner wanted a listen. I had Random Access Memories playing by Daft Punk at that time. She didn't wanna give the headphones back, needless to say she absolutely loved the way the HD800S sounded. The Piano piece at the start of the song 'Within' is something else on the HD800S. Playing Dave Brubeck live on this is fabulous. The drum solo in 'Take Five' pretty much sealed the deal. Yep, I am gonna keep them. I paid $1100 USD for them here in New Zealand from a store (Computerlounge.co.nz). There was a promo going on for 2 days - 30% off all Sennheiser products. They had 3 HD800S and 3 HD800. The HD800S are all sold out. The HD800 are still available. I have had Audeze before (LCD-X) and they are no match for the HD800S. The only thing the X did better was sub-bass. The X also sounds more coloured in comparison. What I have come to realise is this - These are very natural sounding while giving gobs of detail. I am rediscovering my entire music library. Anything with real instruments and the HD800S just shines. The WA22 is running some very good tubes along with Jupiter Copper foil caps and Mills resistors (made a big audible difference). Time to pour a glass of Whiskey and roll some tubes to see how it affects the HD800S.
