Hello everyone,
While doing a late night listening session with my good friend Crown Royal...I started wondering what the cordless phone in my dedicated listening room might be doing to the noise floor , if anything. The phone is the only thing I have plugged into an outlet in the entire room (non-audio equipment that is). Sure I could remove it, but I would have to go upstairs to answer the phone if I did. Should this be a concern? I figured other inmates would shed some light :-)

Uh, being CORDLESS and all, couldn't you charge it upstairs and just keep it with you off the hook? Still works you know...
Hi,
I second (or third?) Mr. Sekela's input, emphasizing that the other electrical appliances are most likely creating a noise floor, regardless of the room they're in. I've been told that appliances in other homes can even create such noise. I tried to combat this with dedicated 20 amp, seperately grounded circuit (purist would actually have seperate circuits for amp versus upstream - but, I had my limits!). I also added a PS Audio power plant - which regenerates the AC via conversion to DC and back again to AC. I have very black background; I can't recommend a power plant like this enough (as contrasted with power filtering devices; I don't really understand how they can work.)
Happy listening!
... just put it somewhere else, assuming you have other phone points round the house.
If you mean just a phone then maybe it does when you use it, but at that time you are talking on the phone not listening to music.
Maybe you can get someone else to try using various electrical things round the house while you sit and listen and... and make sure they don't think you just don't want to do the housework!

As Al suggested an experiment might be in order here.
I choose to live my life with my music and hence I have my laptop (wireless), a cell phone, a cordless house phone, four Tivos, and who knows what else in my listening room. It may make a difference but even so I'm not going to change how I live for the last few drops of sound :)

If it has a switching power supply and is fed from the same circuit as your audio system, chances are good that unplugging it will improve your sound. If so, put an AC filter between it and the wall plug.
IME, any appliance anywhere in the house has a chance to be a source of RF noise that degrades the sound. So far, I've found that the furnace, air conditioner, garage door opener, refrigerator, microwave oven, dishwasher, clothes washer, clothes dryer, my wife's DVR/TV setup, the computers' UPSs, and the little supplies that feed the Roomba and her laptop, are all sources of RF noise and that the sound benefits by installing filters on the appliances. The filter on the dishwasher made it difficult for the main motor to start, so I replaced it with a switch.
The telephone line may also be a conduit of RF noise, especially if you have overhead service in your area. Adding Power Wraps to the telephone wire where you can get to it may help.
...and if you hear some noise being added to the signal by the phone base, here's a great filter to plug into that same outlet:
