Not a Krell owner, but I don't think it matters with this question.
I leave all solid state audio equipment on 24/7 unless I am out of town or there are lightning storms predicted for my area. (Amp, Pre and CD player) I turn on my turntable and phono-pre thirty minutes prior to using them so that they can achieve thermal stability.
Personally, I think the power up and down cycling is more likely to cause problems than leaving them on full time. Most of the items are pre-owned so warranties mean very little to me or do not apply. This may not be energy efficient but hey, you are not paying my power bill.
