I have lived here 9 years with no real power issues. I would get the odd subtle pop from the fridge but it was barely noticable. We had a new boiler with water on demand installed a few months back and right after that I started getting terrible pops and clicks through my speakers. The boiler is frequently turning on and off because of the water on demand feature. On advice from an AK'er I contacted the manufacturer and I was informed that there are no RF or EMI filters in the unit or available as an add on. There are 3 suites and 5 adults in the house. We all work days so first thing in the morning and around supper time the boiler can turn on 3 times in 5 minutes. It's nuts. I miss the old hot water tank. Presently when the fridge turns on or off I'm getting much louder pops than before and the worst ones are from turning on a fluorescent magnifying lamp I have or the fluorescent ceiling lights. KABOOMY! Now when my neighbours fridge starts I am getting audible pops. That's a new development also. I just rent here and my landlady won't spend 2 cents she doesn't have to, so I'm on my own with this problem. I picked up a new Furman Elite-15 DM-i today and there is no improvement. The Furman rep said that the unit would take care of the issues but it has no effect whatsoever. Bad unit? Maybe the Furman isn't capable of resolving these issues. Perhaps there is an problem with my old Akai AA-1200 receiver? Occasionally there would be a hum but if I wiggled the left channel turntable RCA cable where it plugs into the receiver the hum would cease. I opened it up to repair it but things in there are very tight so I chickened out. Sending the Akai out for a service is on my to do list but since I bought a separate phono pre I have put it off. I have another old receiver but it has 8 ohm outputs and my speakers are 4 so I can't try that. I haven't played records in a couple of months now because I don't want to damage my system. It's not just the boiler affecting my system now. Could it be that something in the receiver needs attention or failed? As always I appreciate any thoughts or comments!
