You didn't describe your cabinet. If it has glass "doors" then you really shouldn't need anything special, sunce IR signals will penetrate glass. You may lose a little of the "power" of the signal, which basically is manifested in just how far away you can be.

If, however, the cabinet's construction is more solid (not glass), then it would be more akin to having your components in a "closet". RF signals will "penetrate" normal wood or composite materials (non-metallic). Since you said "cabinet", I'll assume that depth is greatly restricted, thus most or all the components are just barely behind the cabinet's face. That precludes putting the "command center" in front of the components such that all the components would get a "good shot" of the IR signals from the command center. Therefore, you'd likely require the use of "emmitters" or "bugs" or "IR blasters". These are small IR emmitters at the end of cords which plug into the command center. You tape or use the self-adhesive the small emmiters over the "IR Windows" (sensors, receivers" on each of the devices you need to control.

That leaves you 2 options: an RF/IR remote w/command center, or a set of one of the various "pyramid" schemes available. The pyramid schemes you simply use a normal IR remote aimed at the transmitter pyramid, that sends an RF signal to the receiver pyramid (in the cabinet) which converts the rf signal back to IR to control the components.
The IR/RF w/command center would possibly gain 2 advantages: 1. No transmitter pyramid, since the remote itself sends the RF signal that the command center receives which in turn converts to the IR for the components to actually use. 2. You wouldn't neccessarily be restricted to the same room as you would with the dual pyramid scheme; ie., you could change tracks on the CD from the kitchen or bathroom. Since the remote is essentially non-directional, you wouldn't have to "aim" at the cabinet. If your receiver is also in the cabinet, and also IR controlled, you could also control it's functions with it as well. If the receiver is not in the cabineet, since the remote also sends IR, you could control the receiver IR direct.
2 currently marketed remotes that sell for ~70.00 for the remote and command center that should easily handle your needs are ueic's (One-For-All) 9910, and Radio Shack's 15-2117. A further advantage is they are both JP-1 ready. That would let you control all your IR devices with just one remote, from virtually anywhere in the house/apartment.
The dual pyramids would also probably "work" but you'd be restricted to one room, and a multitude of remotes to keep track of and keep around. Your choice and decision.
