I'm not sure I understand your question. A few more words would have helped. The technology in the 9000 is marginally better, but the construction, and cabinet in the SCD 1 are better than the 9000.
I would not trade my SCD 777es for the 9000, you should not trade your SCD 1 for the 9000 modded or not.
