We thought about 3 level power management for many years. There are ways it could be implemented, but it would be complex and the benefits may be small so I'm not sure how worthwhile it would be.

We already shutdown USB when it not in use.

You mean 'idle' state? AFAIK it rarely used and have little sense. Or I wrong?
saratoga:
One way to do it would be to have codecs inform the playback engine of their estimated complexity (or have playback measure it). Than the boost and/or unboosted frequency could be changed depending on the codec being decoded. So FLAC might set a very low unboosted frequency or ape a higher boosted frequency.
g.orlandini:
Hi Saratoga and Mikhail,
maybe we could have different frequency presets (normal and boost) that we can select from menu (after a rebooting if needed) so if we listen to files easy on CPU we can select from menu an appropriate set of normal and boost frequencies. For example preset could be 32-128, 38-192, 38-256 and so on...

Hey, sorry for the delay in my tests, had a bit of rough week.
Sandisk 128GB is still giving me 200+ reinits, even on basic playback and seeking with v.6
Sandisk 200GB - 1 reinit (tried IT, MOD and Opus)
Samsung 128GB - 1 reinit same tests
So it appears only the Sandisk 128GB is demanding.
