I’d say, like most things we buy, there is a minimum quality standard that should be adhered to. That being said, there are both acoustic and aesthetic advantages to be had if it’s in your budget.
I built my own by repurposing some walnut furniture into a number of shelves that can be configured in a multitude of designs based on where they are placed in the space.
Ive had these as one tall rack, two medium racks and recently into three short racks. Connectors are 3/4" black pipe from Home Depot. Most components are on IsoAcoustics Gaia footers, IsoAcoustics Orea or IsoPucks.
