I've owned a Plinius 9200 for a year and leave it powered up 24x7 and strongly recommend doing that for best sonics as Simple says above.
I'm extremely pleased with the sound of the Plinius 9200. Be aware that it does have a long run in (burn in) for it to reach its peak and at that time it will show the limitations of weaker components in the signal chain. I ended up buying new speakers, Meadowlark Ospreys, and the combination resulted in a very good soundstage with excellent imaging, excellent overall timbre, and the best bass control I've ever heard. The soundstage is better than what I've heard at several dealers with equipment that costs a lot more than my system.
