Cary SLP-05 Capacitor Change

Has anyone upgraded the caps in their SLP-05? There are at least 21 caps including:

6 - 1.0uF - 200V
4 - 2.0uF - 400V
10 - 0.33uF - 200V
1 - 1.0 uF - 400V

The photos I have seen of other mods showed a replacement of the 6 1.0 uF caps. My guess is they are for output. I am not sure which would give me the most bang for the buck.

Any insight would be appreciated.
