I'm a long time lurker on this board and I have a ton of questions to ask, but I'll start with the easiest one What components do I need for a rack? The only things I'm sure about are the Rack itself, the Poweramp, and the Preamp. What other gadgets should I use? Power Conditioners, Compressors, Tuners, Ventilation, etc. It all confuses my small brain very, very, very much. Thanks.
