I have found that arhaus and pottery barn furniture have the widest and deepest cabinets but they are $$$
Not to bash IKEA cause I have slot of their furniture in my house to just get by but I don't think I would trust a pull out srsr rack on cam bolts and particleboard!
Salamander designs is a furniture company that designs their cabinets around AV racks. They are nice but I wouldn't put the quality up there with an arhaus/pottery barn/Ethan Allan/ whatever fancy manufacturer
