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..  :(

Dear @scm  : Looks as you are rigth, it's through the air and picked up by the cartridge/tonearm.

As you said it it's not easy to fix it other than change the TT positon or even its shape/angle position.

Regards and enjoy the MUSIC NOT DISTORTIONS,

Here is Max Townshend stamping his foot on the floor, proving once and for all vibrations travel just fine through solid concrete. https://youtu.be/BOPXJDdwtk4?t=86 

I am constantly astounded at the ability of people to ignore solid evidence and persist in wrong thinking, even to the point of talking about moving a turntable to a whole different room, rather than just try what has actually been shown to work. The guy repeating the concrete good to go BS knows it is BS, but keeps repeating it. The guy talking about moving his turntable to another room can solve his problem with some $30 Nobsound springs or even a $5 box of sand. But no, the Good Ship Nonsense has a full head of steam, full speed ahead! Absolutely amazing.

I`m talking about feed back/added content that`s coming through the air and getting picked up, not mechanical feed back like floor bounce, footfalls etc..

If so then you need a room treatment, order acoustic analysis of your room and buy absorbers, diffusers and bass traps for your room.

Concrete floor is the worst material for listening room, if your walls are similar then it’s terrible.
