'Racks'. Important? Best bang for $$?


Hello, all you rack enthusiasts out there in Audioland. it has come to my attention, in pursuing ISOLATION devices, a rack can either add or detract from the sound one's gear is capable of producing... Wow!

I recently changed mine and went with something more esthetically pleasing, not knowing or even considering how it could affect the Sonics of a system! I found out the hard way. Things got worse. A lot worse! I imagined all sorts of issues and addressed them all, save the rack. .. and only by accident did I find it to be the source of the negative swing in sound quality to my system.

Being convinced, now, a good rack is an important & integral part of the 'system', I would like to prevail upon those of you who have found good quality racks, at affordable prices....

Should they have stone shelves, absorbant, wood, isolated, etc... Coupled or uncoupled?

I think several are in my future... one for preamp & amp. One for the sources, (3, no phono though), and another for proc & multi amp.... it would seem ..or some combination that supports those items. Access, cooling, and ease of assembly unless it/they come put together, are noteworthy too.

Sure would appreciate some other experiences here, if you please. Many thanks.

Blindjim,

I prefer two legs on one side and one on the other. It makes access to the rear of the components much easier. Like I said I've tried independently splke shelves and there was very little difference V's one piece legs, both using 1" width maple ply. As you said you could put a slot in the legs rather than a basic butt joint but you need a router I guess.

Jadem6, Have you tried making a rack out of ply ? I think you'll find it's lighter, more than rigid enough and damps vibration far better than any metal. I think there's an argument to be made but mutiple layered composite materials like carbonfibre for instance, but metals are in general very poor for absorbing/damping vibration. There's a reason various musical instruments, photographic supports etc stay away from metals.
I found Plateau to make a reasonable priced rack and I found the quality first rate; they also do AV racks, which are lower and worked nicely in a HT application. See my system where I put two of the AV racks together to fit underneath screen. You need to determine if it's worth your time/energy to put half the cost into materials to end up with something that may not look as slick as a mass manufactured piece. If you consider your "hourly wage" in the fabrication of the stand(s) you may not be very far ahead in DIY. One site to look at is racksandstands.com
They have Plateau.
Douglas_schroeder ...nice looking rack. ...and good point. I've thought about that as well. time and materials add up. however my time is compensated by the end product. Consequently the energy in formulating and generating the exercise have more a value in the process, than perhaps the result as the purpose serves other areas. ...ex. Keeps me off the streets (always a good idea), I'm learning a whole lot here I didn't know previously, getting to build again something that ought to look decent and at least be a suitable platform, and the learning experience is I think worth it. then there's the acquisition of more power tools, and that's always fun.

though your statement is spot on valid. Thanks.

Given what I've been reading online about Stillpoints, rollerbolcks, tune blocks, etc... and the posts above, I don't see myself going far wrong making one. in fact, either way for that matter if suitable 'cups/points/blocks' are employed as well. It is a gamble. but so is everything else. Even the Symposium isis rack and others indicate added benefit from these little footers. Which to me says the structural support is not the end all be all for isoing a system... just a good foundation to add to... well I think I can make a good foundation... and would like to find out.

Now it's just feasability of gaining the tools. Seeing the numbers of it all will tell me what I need to do or which way to go.

the aspect that interests me most is the platform base approach. Wherein one unit can be made (and of course replicated) at a time for components... preamps and/or sources, primarily. thereafter, 'stacked' atop one another. that method allows me to see things as they interact a step at a time. Hopefully that should be of some benefit. Easier too I would think.

it seems sane enough to me. Finding such 'individual' bases already fashioned would also be a good thing... again, depending upon price per each.
Anybody familiar with Ultrasonic?

The deHavilland room at RMAF sounded great on these racks.

I've been looking at Grand Prix, but the coin is just, well, way up there, especially when you need a rack + 2 monoblocks stands.
Continuing to pursue this effort I saw some print online about "pARTicular" racks. Racks that can be upgraded after the fact. Entry level units aren't exceptionally high priced... but surely no give aways. the man sold his plans for one rack system to the people who now make them under the name of Lovren. Made a tidy sum too.

Anyone now using the pARTicular racks? thought I'd ask. the man, whose name escapes me now, was also winner of design awards as well as highly sought after early on in his endeavors by then newcomer BAT for shelving their devices at shows... along with many other makers of high enbd audio gear. Just thought it noteworthy to pass along.

I've likely made up my mind about the brand rack I'll try. I also will build one just to see how they compare... and I've enough stuff to fill both anyhow.

Any other over achievers or giant killer racks out there? I sure wouldn't mind hearing about them... it's not too late...

Thanks.
