Power help

The APC UPS puts out terrible, square wave power that’s full of noise that even the best linear power supply can’t clean up. The APC also doesn’t cutover cleanly from utility power to battery power.  You could go with an on-line pure sine wave output UPS like the Eaton 9130. The only downside of the Eaton 9130 and other high quality output UPSs is they have noisy cooling fans, so they need to be located outside of the listening room. 

@kosst_amojan your message is contradictory. Re-engineering a power supply will be nearly impossible for most people who don’t have the knowledge or means. Even for people who have the knowhow, the cost of upgrading power supply upgrade parts and real estate limits inside the components is another limiting factor. It is infinitely better to solve the problem at the source by adding a good UPS or at least a good power conditioner. 

Noisy expensive UPS located in another room does not seem like a reasonable solution. I’m pretty sure I had a dedicated circuit installed in my media room last time I had an electrician over. I think the variability in electricity in my house comes from the source. My whole neighborhood has issues. I realize that is a limitation. I didn’t want to put that stress on my equipment so I got the UPS to help minimize the impact of these occasional brown outs. 

Would going to a wiremold powerstrip and then to a UPS help?

Is there a reasonable priced UPS option that is not noisy that would be a significant upgrade?

Should I not be concerned about the variability and just use a wiremold?

Would one of those Blue Circle or other power conditioner products in between the equipment and the UPS help?

Is there a reasonable solution that I could hire an electrician to help with?
