I bet the more complicated the music the more the desirable parts of horn speakers will be shown.
I said I would never buy another Turntable...Argh !!!

Respectfully, this is not consistent with what I have read in serious acoustics textbooks discussing sound absorption (NRC). I think the lists of materials and the NRCs thereof indicate that 3/4" hardwood reflects less sound than common drywall.
I guess that depends some on how you think about it. The reason I say wood reflectors better is because it has a failry even FR in the reflection. Drywall gives you a garble. This is a reason why a wooden room can be beneficial, as it’s consistent in the audio range. Wood rooms can sound “alive”.
But you’re right, wood is fairly good at passing sound from one side to the other.

The subject is debated in the F. Toole book - the available acoustic data is collected for normal incidence and is of use mainly in large spaces. However in small rooms the incidence of critical sound rays is mostly oblique.
As far as I see NRC is an average coefficient of absorption - it is used mainly for isolation purposes, but a poor indicator of reflection. It should not be used for the design of audiophile listening rooms.
System coming together. All gear here except for David’s Nothing rack and AS2000. AF1 TT will be up and running tomorrow.
And that’s putting the system on a diet....one less TT and rack.
That Nothing sure looks like something!
In the sequel to catch 22, Milo Minderbinder (for those who don't know catch 22 he is a shrewd businessman in the story) sells the Pentagon stealth bombers that you cannot hear and you cannot see. This Nothing rack should have been sold that way, a rack where you can hear nothing and where you can see nothing.
Me too - considering the density of stainless steel is around 8g/cm3 I am still trying to estimate the total weight of the rack...

David has estimated around 700-800 lbs. I wish things were lighter in the TT world....lol
If you were not careful assembling it then I bet your toes would certainly be singing a similar tune.
Vinyl now spinning. Second shot is the 24’ ceilings. Headroom used to be 8 ‘. Music fully blooms now before hitting the ceiling barrier. Taped area for AS2000.
Christian,
i'm skeptical that your wood floor can handle the pounds per square inch of the feet of the Nothing Rack + AS-2000 without some unpredictable deflection. whether it's deformation of the wood, or the support beneath, i'd recommend some consideration before it's all in place. if those wood slats are directly over concrete maybe you are ok. but maybe not. if it's directly over concrete i would think about cutting out the wood in that area to get directly onto the hard surface.
once it's in place and deflects (each footer will not deflect equally) it will be hard to fix it.

I think he posted a picture of bracing it earlier in the thread.
The room is a pretty serious upgrade, even if the corner is a little scrunchy because of whatever the rock barrier stuff (fireplace?).
