VTi A/V Racks: The BL-Series 300/400 series are great sounding/ isolation racks. In fact, any design that uses a similar stacked/de-coupled design is highly desirable. VTi appears reasonably priced.Such equipment racks of similar/identical design include the 3-post Lovan (discontinued) I've been using for +15 years. A great 'sounding' stand.What's really exciting/upgadeable about VTi 300/400 series is its rectangular shelving; enabling user/audiophile to use/cut additional shelve material (in place of stock mdf) to improve performance further; acrylic/plexiglass, plywood, exotic wood, stone, composites -or whatever may be thought of or recommended.
You need not consider a more elaborate or expensive rack system -it simply isn't necessary beyond what these modular/stacked/ Isolated designs provide.
