Game Changing Tweak
The products we're discussing were developed over years of sophisticated research, using all of the instruments that meter/measure electrical signal.Then where's the data? The mfg rambles on about Fourier, so do an FFT on the line and the program w&wo the gadget. For under a C note, one can obtain a PC based scope that will do FFT. He's set up award winning rooms at audio shows for years.Said rooms almost universally have the most gawd awful sonics. |
If a device adds harmonics, the voltage is going to change See http://ielogical.com/assets/Audio/misc/SubHarmMod.png for a simple example. Power supply diodes only conduct for a fraction of the AC cycle. If the AC voltage is modulated due to increased harmonics, it is going to change the diode conduction period which in turn will modulate the DC supply and not in concert with the music demand. If the added harmonics decrease the voltage at a musical peak, clipping is more likely. Never a good thing. Some like valve rectifiers because they modulate the power supply in concert with the program. More than once, a new WhizBang has elicited the response: "You’re freaking joking, right?" |
Sunshine, I was in the audio field for 20+ years. I have a Grammy nomination, a patent, invented the Vocal Splicer, designed and built 5.1 scoring monitors, was head of Analog R&D for AMS-Neve, consulted for the biggest names in the industry. I endured, never enjoyed, more shows than I can forget. Universally, when people who know live acoustic music hear my system they are blown away by how musical it is and make comments like "Wow. Wow! Awesome!! Joe Pass is sitting right there!" "Man, your system is so precise!" on hearing Warren Zevon ’Werewolves of London’ "Who needs concerts?" on hearing Queen ’Bohmenian Rhapsody’ "Man, it’s like I could walk up and sit in." said a jazz guitarist on hearing Ben Webster ’Remember Me’ |
