Granite countertop remnants are cheap, can be stacked, don't lood to bad, and make an effective isolation platform.
Next tweak to buy?
I have a descent stand and I want to start trying tweeks but dont have any experience with any of them. I have been looking at feet, pads, and the isolation devices that you put on top of and below your components. What do you recommend to try first? What materials and brands are best? Thanks
