Components on floor

@dbphd 

I agree with @ghdprentice, I would avoid placing sensitive equipment close to the electric fireplace. Besides heating elements, the fireplace contains fans, LEDs to illuminate the faux flames, and all sorts of control circuitry. Lots of opportunity for undesirable electrical noise.

Two words: vacuum.cleaner. 

Also, do you like standing on your head to adjust the volume? 

Can someone please explain the supposed advantages of putting your equipment on the floor?

@panzrwagn 

One advantage is that you don't need to spend $15,999 on an Audiophile rack 😃

@devinplombier I could pull an 'Audiophile Rack' in for $9,999, easy. 

There's many variations of "wood-faced concrete floor".

Is the concrete a slab on the ground or a suspended slab?

Is the wooden floor freely floating over the concrete or firmly attached?

My partner's place has a concrete slab on the ground, to which solid hardwood planks have been attached.  The planks are Australian hardwood - red ironbark to be precise. This stuff sinks in water and can be machined like metal billets!

The installers lined the floor with a waterproof membrane then fixed thick plywood sheets using explosive nails, Each hardwood plank interlocks to the next, and was glued and edge stapled to the plywood.  The whole thing is about as rigid as you could get.

Mostly, Australians use floating flooring using manufactured sheets of mdf with a thin veneer.  The sheets interlock and sit on a foam or rubber underlay.  There is no positive mechanical attachment anywhere and gaps are left at the walls to allow the floor to expand and contract.  The floor bounces by design.  That's what my partner used to have.
