I found that the benefit was immediate when I installed the ring/clamp on my Scoutmaster. However, even greater improvement is gained from the SDS. Dollar for dollar, I would get the SDS before the ring/clamp. Mass is important for damping, but correctly maintained speed produces a greater listening improvement, believe it or not. I believe that the best order for the improvements on Scout types is 1st SDS, 2nd Ring/clamp and 3rd Mini footers. In fact, don't buy the mini footers ( the cost vs the improvement is too great)and save up for the super heavyweight platter. I have the footers and am now saving for the platter (greater mass/damping/flywheel effect is the name of the game).
