Caterham: I finished the MDF shelving yesterday and had two shelves cut. One with an off center hole and one solid. I could not hear a difference between the two though neither sounded very good with my Musical Fidelity amp resting on them with its stock "integral" feet. I am not very articulate at describing sound so I will just say that I lost HF shimmer and a little LF definition as well. The amp was previously resting on the Persimmon wood of the cabinet and this combo sounded much better. I tried mystery adjustable speaker spikes (free from a friend) between the lips and the shelving which also made very little difference. I suspect that the problem is that the 3/4" shelf is 24" in width and I will try 1" thick high density board next. My lumber yard did not charge me for the MDF or the cuts which means that I am probably due for a shave and haircut. I will keep my ten year old T-shirt and shorts though. The CD player is still resting on its original layering system below so it is just the amp shelf that muddled up the sound. I may try terra cotta and other ceramic tiles under the amp(s) (my second one arrives this morning) as I have never used these materials and they are dirt/clay cheap. I was also able to free up 2" of space below the source to try the Mapleshade cones which I will order today. Since I will be burning in a new amp and cable I will not be able to experiment for a while as there are too many variables to account for. If tiles or other thin layers do not work with the MDF the amps will be going back into kitty territory for the time being until I try a 1" shelf of MDF or another material. I only have a 12" height to work with in the cabinet which severely limits my options. I will save the good materials (2 1/2" maple and marble) for a freestanding rack that I will build when I am more active. The freestanding rack will allow me to have normal cable runs and better speaker placement but will have to wait until the spring/summer at the earliest. I can barely move after putting together this simple shelf and my wife is not very supportive of any more construction projects for the time being. I will be certain to copy this thread for future use and will add comments in regard to the Mapleshade cones, etc., when the accessories arrive and settle into the system. I wish that I had a way to "beam" my maple slab to Redkiwi, it must weigh at least 100 pounds.
Shelf Material
I have tried so many different shelf materials, and some are better than others, but I feel like I am just spraying bullets that always miss the bulls-eye. So far, I cannot live with the brightness of glass, the ringing of marble or granite, the sluggishness of acrylic, the muddiness of mdf etc. Light and rigid seems better than heavy and dense - in that I can live with the downsides more easily. I use heavily constructed welded steel racks - spiked to the floor and upward spikes supporting the shelves - and I reckon this is right. I like the way bladder products get rid of the resonances that plague shelves, but find that the way they slow down the pace of the music is hard to accept. Does anyone have some answers on this?
