Looking to buy Static Voltage Stabiliser for led tv + hifi system

[Sean de Silva]

I'm currently reaching out to a few manufacturers. Most of them have 2.5kva, 3kva or 5kva offerings in single phase. I'm veering towards 3kva or 5kva. Since these bulky devices aren't exactly cheap and will obviously be a lifelong investment, I would greatly appreciate recommendations and advice from all those who are successfully using a static voltage stabiliser for their led tv + hifi system. What red flags should I avoid while shortlisting these devices?
