I went for the budget option, used a couple of 18" x 18" paving slabs under my spiked speaker stands, definite improvement, especially as the floor was of the suspended/chipboard type.
Cheap and cheerful.
On the aesthetic front, the edges (underneath) were be a bit rough, easily fixed with a course sanding block, I gave them a couple of coats of emulsion paint and a final coat of varnish (quick dry acrylic, easy to use). One of the small 'test pots' will do two coats per slab.
The ones I chose had a small regular dimple pattern, like very small bubble wrap, so I found the spikes sat quite securely, but spike shoes would be another option.
