In response to your initial question I would agree with Jond, leave the DAC and the transport on.
However, since the topic has gone a bit further into the value of warm-up from cold start vs a constant on condition I've made an observation with a SS CDP left on 24/7.
When the rest of the system has been operating well past any reasonable warm up point (all tubes) when I use this CDP (Wadia) initially the upper frequencies are definitely overbearing in the highs. Dissapears within about 30 minutes or less (replayed the disc to verify). Thereafter, in that session there is no problem whatsoever.
Anyone else observed this in a different, or same, devices?
