In Reply to: Wi-Fi makes your system sound worse posted by Charles Hansen on October 14, 2005 at 16:32:51:
An equipment shall work as specified (i.e an audiophile eqt shall not exhib any degradation of sound) in ANY variation or combination of variations occuring in its environment, as long as these variations are in the standard-specified range.
An equipment that doesn't fit with this requirement should not got its receipt by its manufacturer. Furthermore expensive equipment. It is in no way acceptable.
We had a thread about it some time ago with Dan, Al and John, see my post in link below (paragraph 3 is about EMI/RFI)Those environment parameters that shall be specified include (among others) EMI/RFI susceptibility. Current (and even 20 years old in this matter) radiated EMI/RFI standards are done in a way that levels of Wi-Fi, BlueToth, ZigBee, GSM and 3G cellphones, leaky uwave ovens etc , are well under the susceptibility level with a wide enough margin.
So, NO, these RFI sources shall NOT "cause audible degradation in a hi-fi system". Or there is something rotten in the audiophile kingdom.
Further, countermeasures to avoid EMI/RFI problems are easy and cheap, if thought about from the start in the equipment design process. So, there is not even the excuse of complexity or cost.BTW and O.T:
In other topics, I would say the same about mains. As long as the mains stay within the contracted limits between the power company and the customer (limits which are standards), no degradation should occur. Or in same topic, noise inserted in the mains. Or common mode noise. Or unspecified mains source impedance. Etc etc.
Or about temperature and temperature changes.
Etc
