dcancastagna,
I don’t have a slp-05.
But I do have a lot of equipment - all my home theater source equipment on one rack, and beside it all my 2 channel equipment (which include Conrad Johnson Premier 16LS2 pre-amp, Conrad Johnson mono block tube amps, an Eico HF-81 integrated tube amp, Benchmark Dac, Transrotor turntable, phono stage, JL Audio crossover, raspberry pi server...)
I have most of it plugged in to some Furman power bars, as they are good quality, a perfect design for where they had to go, and I at least wanted some level of protection as we have quite a number of futzes and power outs in our power.
In my own research looking in to power conditioners, and looking in to what people from various sides had to say, I was not sold on them. And it did seem that even the more "objectivist" electrical engineer types seemed to agree that they are more apt to be deleterious than beneficial - e.g. they can in principle limit the power going to your amp when it needs sudden big surges. So most said best to just plug power amps in to the wall - most people’s power is fine and most decent amps have a power supply designed to handle the level of noise they are most likely to encounter.
I had a dedicated line put in quite a while ago, and my amps go in to there. My sources/preamps etc go in to the furman power bar.
