Hey Opp, you still there?
Check out the Studio Tech Performance Series. If the 4 shelf version has the same features as the 6 shelf then it has adjustable upturned brass spike supports for "all" 4 shelves.
I have been using their older PA series (same spike feature) for 3 years now and it is a very good unit. The current 4 shelf model is/was available online discounted for $199 (including shipping).
The basic rack is good, just add better shelves, either DIY or commercial, for the source components if you wish (being anal this is what I did). I also mig welded it into a one piece frame (free and 2 minutes work @ my mechanic's shop), but this was probably overkill as the rack was quite rigid before the alteration.
It's less expensive due to the modular (bolt together) design, not a problem, IMO, and it is the only rack I could find in the under $600-$700 price range that offered adjustable spikes for all of the shelves.
I will be adding 2 more source components to my rack (moving the tube preamp/amps to a wall shelf) and will use either Baltic Birch ply or the top of an Ikea Lack coffee table for the new shelf material. I currently use Neuance shelves under the CD /TT, but do not want to spend this much for a CD burner and a Nak 700ZXE tape deck. A half sheet of Baltic Birch ply ($65) will make 4 shelves and the Lack coffee table top ($20) will make 2.
