I have recently added a 12v 3A low noise linear supply to my range which would be ideal for the CD2.
It uses a large 6A potted external EI core transformer which is very quiet & definately no magnetic interference as it can be located well away from the PSU itself. All components are high quality (no Chinese stuff) with a total main filter capacity of 20,000 uf.
I recently supplied one for use with a nimitra sever with good results.
