Measuring line noise and power conditioners

utput555

... my $500 power conditioner (name withheld to protect the potentially innocent) appears to not filter any noise per the Trifield readings. In fact, with some of my outlets the measures are higher through the conditioner’s outlets ... Can anyone explain?

It's difficult if not impossible to offer any meaningful suggestion without knowing more. Telling us it's a "$500 power conditioner" tells us nothing.

Yes, unfortunately a lot of products sold are a bad joke. Your house is separated from the grid by a transformer. Any irregularities are coming from the other houses connected to the same transformer. Remember the main line is 8 KV or more. If you want the absolute cleanest power possible you need a large bank of batteries and a good inverter. You could drive your system with solar panels. Just stay away from class A amplifiers. All this stuff about power cords, conditioner and fancy outlets is nonsense. Spend your money on a better amplifier or cartridge. This will make much more of an improvement in your system. Audiophiles are extremely gullible and the market takes advantage of this big time. If you want to spend a lot of money making your system look nice wonderful but don't think anything is going to sound better. It is not.

I recently put a Hydra 8 into my system. Measured EMI with my Alpha Labs meter and EMI noise was cut in half.

@slaw Do you like your Alpha Labs meter?  Been thinking about picking one up.
