Great news you like the synergy with the SIT-2.  Look forward to hearing more.

My latest development is putting the Nenuphar's on Townshend Podiums (I've been using them under my speakers for a few years). toetapaudio listed the many benefits of this isolation device, so I"ll just say that the cumulative effect takes the speakers to another level I wasn't even thinking was there (the curse of the audiophile).  Music sounds untethered to anything creating it, it just fills the space in the room quite effortlessly with no emphasis on transients or any part of the frequency range.   Kind of a jaw dropper when you first hear it.  My only complaint is that the foot print of the podium is fairly large and not wildly attractive.  I'm sure Cube and Townshend could design something that was a more compact part of the speaker (purchased as an option?). Yes it would raise the speaker price by $2K or so, but the improvement IMHO is more than worth it.

Steve, glad you tried isolating the speakers and heard an improvement. I think this is definitely something most speakers would benefit from. Townshend are a good commercially available product that work with a variety of speakers. My Townshend platforms can accommodate both the 8 and 10 inch Nenuphar’s. I still use the spikes and cups at the front, they just sit on the aluminium platforms. I secure the cups in place with industrial double sided tape.


Which size Townshend platform do you use? In addition, the Star Sound line of platforms are also very good.

>>>>>It’s not obvious but the footprint of the iso device must be large to obtain the required lateral stability for objects with high center of gravity. Sure, you could make the springs stiffer with a smaller footprint but then the device wouldn’t isolate as well.

The Townshend podiums are size 4 with load capacity E which starts at 85lbs so I put a couple of VPI bricks on top of each speaker since they are about 80lbs each.

Makes sense.
