In Reply to: RE: RFI & EMI Question posted by rbyar on June 30, 2009 at 09:31:30
interference is EVERYWHERE. Your refrigerator's motor, the cable box, your table radio, everything emits RFI or EMI or both. There's no escaping it. Your cables are superb antennas receiving those signals which distort your musial signals.
You will hear more of what various devices do by REMOVING them than by adding them. When you connect them, the difference is noticeable, when you've listened for awhile and REMOVE them you hear how much of that distortion and grunge is being removed.
The fact you don't have power surges and outages is encouraging as MOV based power conditioners (metal oxide varistors) tend to weaken with every surge. The good thing is that they DO work and do a decent job of filtering out the EMI and RFI. I don't trust them here as we have outages and surges all the time...if an MOV fails, and sooner or later it will under MY conditions, it will take anything attached to it to electronic heaven.
BUT since you seem to have rather stable electrical feed, an MOV based conditioner should be fine.
I've used Walker Links on my speakers for years, a simple resistor that filters out the RFI and EMI that your speaker cables pick up...they are fabulous antennas. I was recently introduced to Awe-d-o-file's Magnifiers
which are similar but cost a shitload less, do a great job and will make you run to reconnect them when you remove them to find out if they really work.
Earl's a friend, I receive no remuneration by telling you of this, just your thanks and his...read about them. The link is below.
There is no such thing as too many records.
There is just too little room for them!
Thank you both for the information. Regarding the magnifiers- should they be attached at the speaker terminal end(Magnapan 1.6QR) or the tube amp end?
Thanks again for your guidence.

Hi
They work better at the speaker terminals, because the filter will attenuate some of the RFI picked up by the speaker cables.
Have fun!
I have to admit I never tried to put them at the amp end, but I think Earl at Econotweaks states that you can.

I do state you can as has Al but the first or only pair should go at the speakers. If a second set is used they connect at the amp. I biamp and therefore biwire and use four pairs total.

Question "Authority", the mainstream media sucks - Go Independent and hold BOTH parties accountable instead of just the other guys!
I need music to help forget the reality of today
