Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

Steven, the LTA and SIT 3 sound like excellent choices. I’m hoping I might be able to try both at some point to compare with the Bakoon 13R. For me the fact that the Bakoon will have a matching dac enabling JET SATRI through BNC is important to me. Apart from the sound the minimal concept of their designs very much appeals.

In the photo I did have them with very little toe in, was trying them out.  Now I had them more toe in.. still playing around with placement.

I did not mention the review with any intent to draw you away from your current amp, just for general info

@douglas_schroeder   I'm open to learning and understood your post as such. Thank you again.

My 2A3 amps are a delightful pairing for the Nenuphars (based on my needs / preferences). That doesn't mean I am not open to experimenting with other options, including higher output SET amps.

@toetapaudio I hear you on spikes, generally speaking. For example, I am using Ingress Audio Engineering's RollerBlocks throughout my system.

I will note that moving from the stock spikes and rubber bumpers of the Nenuphar to Eden Sound brass spikes (front) and brass hemi-spikes/spheres (rear) made an easily identifiable and immediate positive difference.

@khragon   I recommend trying the above since (from your photo) it appears you are using the stock spikes / rubber bumpers. The Eden Sound solution, or equivalent, is a low cost change that (in my case) paid positive dividends. An easy first move to squeeze more performance out of the Nenuphars.

[Note: I'm using the Eden Sound spikes 'solution' on Townshend Audio Seismic Platforms]

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.

Thanks @geoffkait  +1 and noted.

@stephendunn  Thanks so much for the detail you shared around your experience and insights with the Townshend Seismic Platforms. I still need to work on optimizing placement / positioning / toe-in / tilt etc.

Your results and findings are very encouraging.
