I Have Airborne Feedback And Never Realized It...Till Now


  While my ZYX Airy is out for a rebuild, I hooked up my CAL cd player/transport and started playing CD`s that I had recorded from vinyl using a Tascam 900.
When I do the recording, nothing is on but the TT setup and the recorder. Room is dead silent. No speakers

I`ve  been listening to a disc or two over the last few nights.

Last night, I was listening to a CD I made of Lindsey Stirling`s 'Shatter Me' LP
I was hearing so many odd/different sounds that I never picked up on before using the TT.

For example, I heard growling sounds (seriously) back ground noises and other THINGS that all were hidden when I was playing the TT.
This LP is Bass Heavy! Lots of energy in the air. With 3 15" subs I know that.

My TT is pretty much isolated IMO
I use a Rega wall mount bracket that is bolted to my equipment rack not the wall.
I have the TT sitting on a SRM isolation platform that sits on the Rega bracket
Concrete slab floor.

No doubt the cartridge is picking up on all energy that and resubmitting it.

This won`t be an easy fix I`m afraid..  :(

In my previous home my components sat on two shelves fitted into a 5' wide alcove along a side wall in the listening room.  I happened to have placed the turntable at the far right end of the upper shelf.

One day I happened to lean over the turntable while a CD was playing with some reasonable bass content.  With my head in that corner of the alcove I was surprised by the bass loading.  So I thought, that can't be good for the cartridge/stylus to be playing in that location.  After I moved the table away from the corner to where the arc traced by the tonearm was near the mid-point of the shelf playback became cleaner and with increased definition.  

That was an acoustic loading problem.
