EXCELLENT! Thank you, exactly the type of parts I need and was looking forš

Hereās the TImbernation rack for my home office. I think thereās plus/minuses to the side-mounted support, the biggest minus that I wish I had the internal diameter 21" instead of 18.5", which is not really wide enough for some things. Slightly deeper would also be helpful for larger components.
This was designed to be 2 vinyl storage on the bottom, then one main component shelf, and a āfloatingā turntable stand on the top on cones. However, since then I had Timbernation make a āin-between shelfā to add another level, and then Butcherblock Acoustics made another shelf on top.
Every floating shelf is leveled by the screw-in feet. Wish I had an accelerometer to see how effective the vibration control is.

GL on you build!

you can put a glass of water on top for some basic indication about vibrations

Thank you @keithc @ericg @Souldriver. All very helpful.
I spoke with Jim at Butcherblock and he was great in answering all my nonsensical questions. Considering the rack has to do double duty, i have to have the tv on the top rack and tt in the middle rack. All not ideal, especially with the tt having to be in the middle rack which has a height of 8". I am going to order a custom dust cover without a back. So it can slide in for clearance. Not going to be as enjoyable to drop in records. I asked about the black to blend in with components and disappear in the space, but it is hand stained and maple is a PITA to stain black according to Jim. Doubles the price.
It looks like the final contender is going to be below in 60"

Ohhh I see what you did there! Bottom half shelving is solidly attached which allows for the extra height shelving above to be modular. Yes this too is a good idea and I bet my builder will prefer it due to the solid and more stable design.
I have been considering a 24ā interior width and 20ā depth. That depth would still not hold a large Lampi but I donāt expect any massive new additions to the hoard any time soon.
Another potential option to consider. Thank you for the pictures. All of you!
Even at 20 Inches (thatās what mine is) youāll need to move the rack away from the wall for the big lampizators to run the wiring if thatās a consideration.

It is possible but yeah a hand stain is prone to streaks when you go that dark on light wood. If it was sprayed it would be different. Or if it was figured maple then it could be stunning but needs the care.
damn thereās some great racks here! does anyone mind to share rough cost? I want to get one soon but am still struggling with how expensive this is!
I really like the idea of a modular design to potentially fit a lampi in there (one dayā¦)

Yeah, nice wood and the work is expensive, and very time consuming and labor intensive. i purchased a $2800 saw thingy for my buddy and in return, for the cost of the fancy wood, he is supposed to build me things. Itās been a few years i figure it is time to recoup my expenditures on his equipment

Very nice rack you have there Keith, creative of you to mix two brands/style into one cohesive looking unit!

Dumb question but how much impact does the shelf and leg material have, if any, on sonics? And one step further is there a noticeable impact when each shelf is decoupled from the one below/above?
The why for this questionā¦
I currently have a diy low 2 shelf hardwood rack made from merbau, the top shelf is sitting on sound card super spikes and not bolted to the bottom shelf. I also have some other gear sitting in an IKEA kitchen cupboard without a front/back next to it (also doubling as a desk support).
I need to rebuild to cater for a torus avr2 isolation transformer in both size and weight so considering some different design options.
The front runner is to build a seperate rack in place of the ikea cupboard and put all my power gear there but the WAF of a second rack is very low.
The runner up is to rebuild the rack to move all gear into one very long rack, so 3 x 500mm bays. Still using hardwood for the shelves but looking to move to premade metal legs like those from quadraspire for ease and consistency of construction ( Iām ok with a saw but 16 legs is a lot).
My brain is stuck pondering will using metal legs sound any different to hardwood? And similarly will having shelves fixed to one another using the quadraspire/solid steel mounting method impact what I hear?

@dB_Cooper posted a bunch of information on vibration, isolation etc.a while ago, i have been looking into it for myself but have come to no conclusion or decision for my own rack build yet 
i require shelving of various heights to accommodate my tube based equipment and Iām almost of the mind to walk away from tubes and simply go solid state simply because of the annoyance that the extreme height requirements come with 
Anyway, do some reading and searching off the provided links and see if anything āclicksā for you. Good luck

I went the isolating the individual components instead of a high end rack. When it comes to the subject, you canāt really over do it. So I have a sturdy furniture as my stand and I put footers on it. With all of my component and the weight of the rack, itās got to be easily 400 lbs or so.
Like @NickMimi the rest of the components are documented in the thread. That link Nick shared is a very good first step into the education of the how the various solutions work. You can choose your course from there.

Either very narrow but deep or very wide but shallow.
Looking at 1,700cm wide by 55cm deep
1700 cm youll have plenty of space for equipment AND to use it as a bowling lane.
But i get what youre saying. I would note that most wood shelves that wide should have some support in the middle to help prevent sagging. Especially as i know most audio equipment can be heavy. Alao think about any natural wood twisting /cupping. Even dry, seasoned wood can move.
My entire rack is a quadraspire svtl and I have only good things to say about the build and looks of it. I initially wanted a Solidsteel HF rack but those had 16 weeks wait time and higher cost

Thankyou
Iām looking at 8 supports per shelf to keep things in check.
Iāll do some reading when Iām back on a big screen, I think the reason for the query is the racks like quadraspire and solid steel use MDF/bamboo based shelves with the aluminum posts rather than hardwood.
