Low AC Line Voltage


Hello all.

I had something very strange happen the other night. My system hasn't been sounding quite right so I decided to try some power cords. I tried 3 Cardas Cross power cables. One on my power amp, one on my preamp and one on my Oppo CD player. I connected them all to an outlet box I had assembled using hospital-grade hardware. I turned everything on and let it warm up for a bit and the sound was totally unbelievable. Big wide open warm detailed spacious deep everything you could possibly ask for. I was totally amazed. The next morning I turned everything back on and tried it again and all of that wonderful sound was gone. It was almost like I had dreamed it. The system was back to sounding harsh and just not fun again. I couldn't figure out what happened. It was that way for several days. I bought a plug-in voltage meter. The voltage is always about a hundred 116 volts or so. This morning it was 123 volts and that wonderful sound was back. Am I crazy or could this possibly be caused from voltage?

Thanks in advance.

@honashagen, I think I was experiencing something similar recently, except in my situation, not only did it affect playback (bright/shrill sounding) but I suspect it probably put the kabosh on my TT’s motor which I’ve had to replace.

The home I recently moved into is 11 years old and when they originally wired the home, they placed the living room, dining room, mstr bedroom/bath on that one 15 amp branch circuit with a 15 amp AFCI circuit breaker.

In addition, we frequently experience power outages and there is a lot of new construction going on.

I’ve since purchased a Furman Elite 20 PFi and had a dedicated line installed.

The room where my gear is setup now has three circuits:

The original 15 amp branch circuit and two 20 amp dedicated branch circuits. The TV I’m installing tomorrow will be connected to its own 20 amp circuit and Ill plug my audio gear into the other 20 amp circuit.

You may not need to take such measures but you might consider exploring installing a dedicated line as an option.

I must be lucky. I live in the land of apartments and my voltage has never varied more than +/- 2 V at any time of the day. It hovers around 119 V practically all the time. It's why I go straight into the wall for my integrated and SACD player.

All the best,
