TW Raven Acustic AC Owners

Halcro,

I do happen to have architectural, structural and acoustic qualifications because of my profession. I wasn't commenting on your specific case, but on cantilevering shelves in general.

Cantilevering shelves made out of wood or mdf will tend to bow over time under such heavy load, hence my use of the term "material fatigue". An engineer can calculate the load of the equipment and design the structure to successfully support that equipment. If material fatigue didn't occur in structures, then there will be no need to inspect buildings and bridges for wear and/or structural failures. Screws attaching a vibrating structure will tend the get loose over time as well, which is why it is recommended to check them from time to time.

I don't know the construction details of your shelf structure, so I can't comment on your specific case. If you used an engineer or an architect for the job, I'm sure it is well-executed.

I agree that a well-executed wall-mounted shelf will work properly, but a not-so-well-executed one will do more harm than good.

This solution is not practical for most and I realize the my not be possible for you. How about thinking out of the bigger box into a smaller box. Put you entire front end in a near by closet on your choice stand solution. Maybe you can spend less money on a stand. Maybe it's slightly more costly and goes grain of having the shortest possible cables in all positions. This approach gives the great isolation from all air and most floor passed vibration. If you have a slab floor then there's no floor vibrations. I've done and hear great results. IMHO having lived with this now, I would never-ever put my front end in open space in my sound room, regardless of great (usually) stand solutions.

There are other benefits too: My musical experience is improved also for another reason because I'm not looking at my equipment while listening - my weakness not yours. My wife loves it readily gave up that closet for this.

Nice system!...
One up from your closet spot, set up of a front end in an adjoining room is by far the best solution...
Especially for those that listen to their music at eye denting levels.

I know how well this works, if you can do it.
Not many can.

Even set up in another room, turntables themselves are resonating devices and I would still try out methods to drain the resonates off.

Isanchez what is your profession?
Your talk of material fatigue displays an ignorance of structural principles.
Apart from ' metal fatigue' which can occur when metals approach their elastic limits after repeated cycling of loads, there is no material ' fatigue' in structures that I am aware of and certainly not in regards to cantilevered wall shelves.
Tightening screws and bolts has nothing to do with metal fatigue.
