Hmm. Duly noted. I will start to consider current generation top of the line headphones and headphone replacement cables if applicable to the specific make and model in January 2013. I just got my Sennheiser HD-650 headphones this past Tuesday, March 6th, 2012. When I got them, they needed to be burned in for at least 100 hours. I have not reached that mark yet. I think it is too premature for me to consider another headphone. Besides, I really want the Cardas headphone replacement cable for my Sennheiser HD-650 headphones by next Wednesday. I can not form a cogent opinion about the Sennheiser HD-650 headphones without the Cardas headphone replacement cable. This Moon Audio Blue Dragon cable is not a good match for my audio system which uses Cardas Golden Reference cabling almost exclusively. I owned the Sennheiser HD-600 headphones with the Cardas headphone replacement cable years ago and I generally liked what I heard. It just sounded right to my ears, but I was using a $120 USD Panasonic portable CD player as my source component at that time. Today, I have a $5,000 USD CD player at home.
I have to make friends with someone who has a Sennheiser HD-800. I can't go by what manufacturers and authorized Sennheiser resellers write for their reviews of the HD-800. I do trust professional reviewers and I have to start researching articles about the HD-800 on Stereophile, The Absolute Sound, and Playback magazine.
People keep telling me that I should get a top of the line headphone instead of the Sennheiser HD-650 headphone for my audio system. I think it is time to listen to their advice and pursue this goal early next year.
In the meantime, I will be buying more music. I do not anticipate purchasing any more audio components for the rest of this year. I have to build up my CD library with recent 2012 releases as the rest of my music is older.
