Review: As Described. Works Great - As Described. Works Great. Chasing down electrical gremlins is always a fun time
Review: ✅ easy to use, helps identify noisy circuits - I bought this product while looking to improve the powerline noise situation in my home office. I have many electronic devices powered from the same line - computers, monitors, chargers - that spew noise back and negatively affect the audio quality of desktop DACs and headphone AMPs. I found Trifield EM100 to be an equally helpful tool in measuring the line noise level and discerning between various available filter products. I wish it had a button or switch to turn OFF its speaker for those of us who keep it plugged in 24/7. Other than that, I see absolutely nothing wrong with it.
