dead quiet

I still don't know what IAP stands for in your post.

Typed into my search engine, Internet Access Point is the answer I got, so I made a joke hoping you would clarify.

Albertporter - IAP = "Irrational Audiophile Paranoia" . . it was coined by Eldartford in his first post to this thread.

It makes sense now, thank you Bdgregory.

Eldarford... The object of the game here in Audiophilia, is to get the purest signal devoid of any artifacts of any kind. One of the reasons that a 15000 dollar amp is better than a 1500 dollar amp is that the parts are better...that is faster (don't hold on to the signal as long), wider, and smoother bandwidth, etc. A component is said to be good when it passes only the intended replication of (let's say the violin). When the purity of the violin's E-string has a 60 cycle modulating tone along with it...it ain't so pure. One of the things that good stereo systems do is to stop playing...that is - there are silences between the notes. Hum and noise simply fills in those silences and blurs things. A very important spec specified on evalutaion sheets is the hum/noise level below signal. No - I must stand by my statement above.

Stringreen...So, when the tuba plays 60 Hz, the violin is messed up. Not in my system. Maybe in yours.
