Thats really tough. My condolences to you and your family. I hope your father didn't suffer needlessly.
I am at the point where I am not geeking too hard and I am just listening more. I have to say that the 800 has revived me into wanting to file through more of my music and get reaquainted with it. But I have also been without music for over a year so some of that is understandable. I have been running it around the clock for the past week and a half or so and I have approximately 200+ hours on it (I face my Revels together then throw two sleeping bags over them to muffle the sound). The change is noticeable. Relaxed would be a good description as it first seemed a tad sterile. It will stay in my system for a long time. I'm likely going to send the CDT-300 back as the differences that I'm hearing between it and the Oppo don't justify the extra money, and it can be used better somewhere else in my system. I still have a little time before I cannot return it so I will use that time. Who knows. I am on the hunt for a Voice now. Of course when I'm ready they aren't to be found. Go figure. One will turn up some time. I'm not hurting and can wait. Hang in there. Losing a parent is really tough. I lost my Mom 3 years ago and it takes time. I don't think the ache will ever go away but time will take some of the edges off. Happy listening.
