Well, my Michell Tecnoarm is going to the TD150 and, therefore, I replaced it on my TD850 with the Audiomod arm. I got it set up and spinning yesterday and listen to it through headphones. Sounds good, but how good only time will tell. One thing for certain is that their manual for set up is the most difficult to read. It is not for a lack of effort, since there are 20 pages of instructions. It is how they have it set up and the lack of good pictures to follow along.
In the end it was worth it.
