MDF vs. Steel Speaker Stands

I like steel, especialy since it is mass loadable.

I'd look for some osiris audionics stands. they should be $200-250 used, but are as good as any stand I've ever heard and are built to withstand wwIII

Simple but nice steel stands are available from B&W for $99.
These include spikes /pads for floor and speaker.
Two post coluum is sand fill-able.

I don't think steel is "superior" to MDF, but the two materials sound different, the MDF being somewhat less forward, IMO. You can mass load MDF stands, as the PVC posts are hollow. For a small speaker like the Spendor, Skylan can make you up a nice 2-post stand that should do the job just fine. Don't skimp on the stands. They are part of the speaker/room interface and greatly affect the sound.

I agree with Chayro, the Skylan stands would work nicely. That is what I use with my Spendor 3/1 speakers. I mass loaded them with a combination of lead shot and kitty litter.
