Symposium is the best made and best sounding of the 3.Good luck!
Comparing Amp Stands and Racks from Adona, EdenSound, and Symposium
I’m upgrading my butcher block maple rack (similar to Mapleshade Sampson rack) and amp stand to either Adona, EdenSound, or Symposium. Has anybody compared the Adona amp stand ($310 with cones), TerraStone DM ($1000), and Symposium Ultra Platform ($799)? They all use different materials with Adona and Symposium using a multilayer of dissimilar materials. The butcher block maple rings. There are good reviews for all products but which one is the most effective while being the most neutral?
