Anyone listen to Zu Audio's Definition Mk3?

German,
Yes that is the aluminum plinth base. As Dave mentions, there is no way you can damage the actual woofer or its surround. The worse that can happen is one of the spikes gets in between the grates, but I don't believe it will go as far as reaching the woofer.

Dave,
I am also considering the Sistrum platform. I know you mentioned that the speaker is still stable on it. But just how stable? I mean if someone (large) accidentally knocked into it (say on a 45 deg. anngle), will it topple over? I just have this worry about something this tall sitting on 3 feet. A big heavy amp no problem.

It's stable...not as stable as 4 spikes on the ground but it's stable. It would take a significant attempt or accident to get it to fall. I had a big "oafy" dog and you nieces around them all the time and never gave it a second thought. Star Sound is not in the business of making stands that cause you to destroy your equipment. Remember that there are coupling discs on between the spikes and the bottoms of your speakers which greatly enhances the contact area and stability. If I thought they were in any way a hazard I would never even mention them for fear I would be partially responsible for destroyed speakers.

I am a very big fan of Starsound and my rig is atop Sistrum stands 'cept my amp. I would put my Def IVs (on the way) on SP 101s in a jiff, but I'm tapped. I replaced my Def 1.5 with Audiopoints. In fact I never used Zu's spikes. The Sp-101s will be a major tweak to look forward to when the time and wife align with the stars. They are a gorgeous looking piece of speaker stand, as well.

Dave,

Did you have your Def 2s on those Sistrums as well? I'm intrigued by what you have to say about them.

In the past I've noticed different footers could really shift tonal balance of the components placed on top of them, did you notice this at all or were they 'neutral' in their effect, so to speak?

Fred,
The Sistrum's were purchased after the Def 4's so no experience with them and previous models. Chalresidad has a good descriptionof the Sistrum efects and I concur with his statements. The difference is anything but subtle. I haven't noticed any significant tonal balance shift with the Sistrums...Quite an improvement in my system.
