A couple of setup changes that might be of interest....
I had an audio friend visit this past weekend. He has broad experience listening to and problem solving for his audio clients, primarily for analog and speaker setups in systems that reach into the stratosphere.
After spending two evenings listening to my system, his primary recommendation was to remove the Nenuphars from the Townshend Platforms.
This relates to @onhwy61 's question regarding driver vs. cabinet contribution and also to @charles1dad 's response to onhwy61 (both posts from a previous page).
For transmission line designs, my friend finds the floor and room interface and their relationship and interaction with the driver critical to sound quality.
The results were spectacular. Even he was surprised by the degree of difference. As he put it, greater than a component upgrade.
The speakers were positioned the same as when on the platforms. They remain on Eden Sound Spikes. They are on a suspended hardwood floor.
After he left, I decided to use the Townshend Platforms for my 2A3 mono blocks. I removed the GAIA footers from the amps and the Timbernation Maple block with brass spikes and Herbie's isolation pucks.
I had to remove the bottom plate on each amp since the screw heads extend beyond the wood chassis. The reason for doing this was to have a completely flat amplifier surface when on the Townshend metal platform. The Townshend Platform has a center perforation; airflow is preserved.
To my ears, removing the Nenuphars from the platforms resulted in a two step gain. The amps on the platforms a three-quarter step gain. Combined synergy, a three step gain. Significant; an understatement.
