Isolation For Bookshelf Speakers On Stands and Shelves

As I am done with equipment upgrades, I'm now focusing on tweaks after getting a little bored. I would like to seek experiences from people who have used isolation products for bookshelf speakers placed on speaker stands and shelves. There are many on the market ranging from low cost to "branded" high cost such as Isoacoustics Aperta and Orea.

The Isoacoustics Aperta is as shown below.

I've watched a Youtube review on the Isoacoustics Aperta and these things are said to work by providing a noticeable improvement in sound quality. However, at a price that's almost equivalent to a budget bookshelf speaker such as the Dali Zensor 1, the reviewer thought it's not exactly value for money as the material is mostly plastic. Nevertheless, this product is said to improve sound quality of bookshelf speakers placed on shelves or on top of tables in a desktop system.

The Isoacoustics Orea is as shown below.

Again, the reviews are mostly favourable but my main gripe on these things is the aesthetics of it. Although they may improve sound quality when used between bookshelf speakers and stands, they don't look good when placed between the stands and speakers as shown in the image above as they introduced a fairly large gap when used in this manner. I understand this is personal but has anyone used the Orea with bookshelf speakers to great effect?

Then there's the cheaper option, isolation pads or felt. These are either rubber or foam material. Currently I have some of these on the top plate of my speaker stands.

I'm not sure if these things bring some noticeable improvement as I"ve never bothered about them or compared them with equivalent or different products. In my mind, they are beneficial in providing some sort of cushioning beneath the bookshelf speakers thus preventing scratches to the bottom part of the speaker.

I would appreciate any experiences on these isolation products either used on top of speaker stands as shown in the photos above or on shelves as shown in these photos.

Have you tried the old favourite Blu Tac.
Yes, tried it more than 20 years ago. I didn't particularly like the stickiness when it left a small residue on both stands and speakers. I thought Blu Tac provided a small sound improvement when compared to placing the bookshelf directly on the top plate of speaker stands.
 
IsoAcoustics do a cheaper version of those stands. I use a set with the active monitors for my Mac. And you can get their IsoPucks in an eight pack for about £80. Both great vfm.
 
If you are using stands then I find using isolation at the base of the stand is much more beneficial.
Replacing spikes with Nordost Pulsar Points was a good upgrade, also Sounddeadsteel squares/discs between floor and spikes is very effective.

I expect Townshend seismic platforms also work well but not cheap.
 
Both of my pairs of speakers bolt directly to their dedicated stands, I did try Pulsar points when they were first released, though I tried them under the stands, they did work and I mean they made a difference rather than an improvement.
The Townshend platforms may work well if you can live with the aesthetic
 
Would defo recommend the cheaper IsoAccoustics stands. I use the iso-200 with my speakers think they were around £85. There is a calculator on their website to workout which size you’ll need. Made a noticeable difference to my set up.
 
I also use the cheaper Iso 155 stands under ProAc, they are available around £80 from Pro Audio shops and Juno on eBay. Before that I used the acoustic foam wedges which work very well and cost buttons, £12 I think. The 155 are worth the money for me, cleaned up the Bass. I also use the Iso Mini Pucks elsewhere to lift amps off the floor.

Just bought some Orea Bronze off Mike in the pfm classifieds to try.
 
Sonic Design damping feet are worth a look. Not silly money. Importantly they come in various compliances to suit speakers of different weights.

If you want the ultimate stand I would be surprised if you could improve on those made by Northward Systems. Northward are high-end studio design specialists; they routinely decouple whole studios and heavy in-wall speakers. The stands are for their customers who can’t do that.

Thanks for all suggestions which are surely appreciated.

May I ask if the nordost Pulsar Points are installed on floorstanders or speaker stands supporting bookshelf speakers? The reason I ask is Isoacoustics recommend isolation between speakers and stands instead of isolation at the base of the stands if the speakers are not fastened/bolted/secured to the stands. I believe the Isoacoustics Gaia has an almost similar function as the Nordost Pulsar Points since they are installed below the speaker stands, replacing the standard spikes. The Gaia is not recommended for bookshelf speakers which are not bolted to the stands as they don't act as one.

Having said that, the Isoacoustics isolation footers come as standard with the stands for Marten Parker Duo as this bookshelf speaker is secured or fastened to the stands.

The Sonic Design product certainly looks interesting as they require the weight at all 4 corners of the bookshelf speaker to be measured for a more accurate tailor of the feet. I can somehow see the logic behind this but not sure if the customisation of the damping feet based on different weights at the front and rear corners of the speaker will bring a more positive effect than having the standard feet applied throughout the base.
 
These silicon blocks from Hudson Hifi are tremendously effective at eliminating the transfer of vibrational energy between speakers and whatever you have them resting on...floors, stands or shelves. And they're relatively inexpensive. I currently have a set of four between each speaker and stand. The massy stands seemed to be overdamping the presentation of the speakers when I first had them coupled using blue tac. I had intended to try a few different interfaces to hold off buying new stands...temporarily. The blocks do a remarkable job. Very little energy gets through them. My speakers now have an airier, more open presentation, and I no longer feel the need to upgrade my stands, or try other interfaces for that matter.

The same basic material is used in a variety of blocks / domes. I'm using the large soft blocks under my speakers.

Felt pads here, and the thicker the better. Sound great (better than spikes/cones or Blu-Tac IMO), don’t do any damage at all to the cabinet, cost pennies and don’t look daft. What’s not to like?

PS If I had kids/unruly pets I’d likely use Blu-Tac as it does protect against a gentle knock and may stop a speaker falling from a stand, but sound wise felt is better IMHO.
