Smart home technology is going to take off big style over the course of the next 18 months. It would be great to use a voice controlled smart plug to turn on my hi fi system, but should I be worried about noise being introduced into the power supply? Are such plugs only active when switching on or off, or are they continuously interacting with your wi fi ?
RF noise in increasing exponentially. Near me there is a LED street lightning. When this **** starts, the 2mts (Yes, 144MHz) becomes full of noise (at about S4-S5 of noise). Oviously, no king of line filter. In the *** of the world, no kind of controls are applied to cheap thrash of this kind.
I am switching power to the power amp on my family room system, which is used for both music and TV sound through a Kasa smart plug. The power amp is a DIY build using a pair each of Tom Christiansen's Modulus 86 and Parallel 86 amplifier boards driven by two of his Power 86 power supplies. The speakers are Linkwitz LXmini. I do not hear any artifacts in the sound related to the use of the smart plug...YMMV.
It’s time has come. It’s gonna happen and there ain’t nothing gonna stop it, well at least on other people’s houses 😉
I would not expect specific artefacts. Just more colourless and lifeless sound. Most people are perfectly ok with that.
So perhaps half a veil was dropped?
Nope...no audible difference from the prior configuration where the power to the amp was switched by a relay driven by a USB output or when the amp was plugged in directly.
chrisb,
I built the LXminis about 4 years ago. They didn't replace anything, I have a pair of Linkwitz Orion 3.3.1s for my main system that I built 10 years ago and when SL brought out the Mini it was a great fit for me as a second system in my family room for both music listening and as a TV sound system. Initially the power amp used was an old Carver 4 channel that I had laying around. I had been following Tom Christiansen's efforts here at DIYaudio and decided to build an amp to upgrade the capability of the Carver. I used his Modulus 86 to drive the full range driver and Parallel 86 for the base drive. A pair of his Power 86 power supplies completes the package. I'm very satisfied with the performance of this system and the sound quality continues to surprise and delight.
