I admire your system. Always loved the Focals!
I hope this gets to you.
I did post on your thread about shelves.
Ralph Karsten of Atma-Sphere told me that the biggest improvement to his system was getting SRA platforms. I got their VR $1500 platform for my Woodsong Garrard 301 and have the same experience. I am absolutely amazed at the improvement. You can keep your current rack and just get SRA platforms. My rack is of a similar quality to yours and the platform has transformed my system. I cannot more highly recommended.
