Dark Star 63 isolation feet – Larger carbon fibre and Blackwood Hifi suspension – Ideal for big speakers


Solidair Audio Dark Star 63 feet are high performance versatile isolation feet suitable for most large HiFi components.


Dark Star 63 isolation feet

These are larger 2 1/2″ versions of the 2″ Dark Star 50 feet. They are similar in proportion, but some applications require a larger foot from a visual point of view. These are better under larger components like HiFi racks and big speakers, where a larger foot looks better proportioned.  This model can be used directly under HiFi components and put straight under spikes. It can be fitted with cork facings (supplied and fitted if wanted) to stop sliding occurring once in place under a component. The feet can also go directly under spikes as they have a cup built into the centre of the foot.

If preferred we can provide the with a stud on the top to screw into a platform or component with a thread of your choice. This thread format has some flexibility if different treads are needed (M8 is common and 1/4″ and 5/16″ UNC are popular in the USA for example).  The feet can also be used either way up and a thread or stud can be put through the aluminium end cap if necessary. There are examples in the images. Add a note at checkout or email us if you have a specific requirement.

The Dark Star 63 isolation feet have a wide weight capacity range and lend themselves to most HiFi isolation situations. We primarily developed them to carry more load and be more stable under speakers than magnetic levitation feet. They have excellent weight carrying capacity, so lend themselves well to this application. They can be used in sets of three for most applications. Visually two feet at the front usually looks best. It may be better to use four feet on heavy amps due to weight distribution and on speakers for stability. For simplicity the feet are sold individually so you only need to order as many as you need, but you will need at least three.

They give a clearer sound to HiFi components, with better instrument separation. Some feedback suggests that these feet give a better dynamic response than their magnetic cousins. Under speakers we have had great results. The sound is lifted in the room as it is decoupled from the floor. The speakers seem to detach themselves from the sound to give a seamless sound stage. “Where have the speakers gone?” and “It’s just a wall of sound” were two of the feedback comments. They also make the sound much easier on the ear, less tiring so you can happily listen for hours without fatigue. We did a demo once for one of our dealers and the room filled with people enjoying what the feet did. I thought I’d remove the feet so the new arrivals could here the difference, I took them out and everyone left! You could no longer hear each other talking, conversation became really difficult, whereas with the feet in place the sound was so clean you could hold a quiet conversation while listening to fairly loud music.

The overall diameter of the Dark Star feet is 64mm (2 1/2 inches) and height around 42mm (1.6 inches). The 63 comes from the tube diameter. They weigh around 50 grams (2oz). Their load capacity has been tested up to 50Kg (110lb) for a single foot, but they look like they could take more. The main body is made from a carbon fibre tube which holds an african blackwood foot on a braided UHMWPE web. They are very strong and do look rather splendid. They can be used as they are on a hard flat surface, or on a soft surface like carpet.

The Dark Star 63 feet and other String Theory HiFi isolation feet have less movement in them than our magnetic range, so lend themselves really well to speaker isolation. If you have not tried good speaker isolation, you will be surprised at how much better your speakers can sound.
