Very nice demonstration. There is one problem. Does ultrasonic noise in an AC lines affect audio quality with well designed audio equipment? I have never seen any evidence that it does. What people think they hear is anecdotal and highly unreliable. You will sell many units based on the belief that it does and psychoacoustic meanderings. You will loose a lot of sales based on the lack of missing information. Finish the job and you can sell me one.
SnubWay Question Thread
Happy New Year
For those interested - the 1st of three Snubber Products is ready for full scale production - SnubWay works really well with Puron, each doing their job in good order.
Viet made a tidy little video to explain the product a bit and make a demo - this is from his What’s On The Bench Videos
We tested ParaSnub (aka SnubWay) with a simulated SMPS noise source that has an 1kohm impedance. This is to simulate a typical SMPS transformer impedance between the high frequency generated voltage and the line (mains) that it is connected to. We inject about 5Vpp 400kHz, 100kHz and 60kHz noise using a function generator and get between -30dB to -33dB reduction in noise (about 100mV to 150mVpp). This is a significant amount of noise reduction and can really help clean up the SMPS noise contamination in our power outlet strip. The level of reduction may vary, and will depend on your particular SMPS noise source impedance, your equipment, and your particular house wiring, etc.
