Measuring line noise and power conditioners


I recently purchased a Trifield EMI (Dirty Electricity) Line Meter to measure noise coming from my outlets. To my surprise, 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, than the measures coming straight out of the wall. The manufacturer denies anything is wrong with their conditioner, claiming the Trifield is measuring the wrong frequencies. Can anyone explain?

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.
Hi,
I have nothing to compare it to. It was expensive. However, it's a nice piece to have.
If we are talking about this meter:

You are measuring starting at 20 kHz and going up.  That is, these devices START measuring noise at the upper limit of human hearing.

While many surge protectors claim to block EMI/RFI, they also claim to start working in the 100kHz ranges, way higher than noise we'd hear.
