My experience, having been down this road with DIY and my store-bought audiophile rack is briefly:
1)The shelving material is a lot more important than the construct/rigidity of the stand.
2)MDF is terrible.
3)This is a very particular area where people get sold theories and believe whatever they want.
4) Light 'n rigid has worked well for me, and not using a good rack is lost potential. Footers are not worth the money, IME for my system.
