Squeezebox Touch.....which mods first?

What are your opinions about the Bolder Cable digital mod or the Channel Island PS? Which one would be the best value?

There aren't a lot of folks reporting vast improvement from power supplies, but the Soundcheck 2.0 firmware mods to disable analog output and turn off wifi made a great difference for me in terms of background blackness and microdynamics. His 3.0 toolbox will be out this week.
