in principle a Rack in a room with music playing has 5 main areas of functionality:
1. floor: The floor gets mechanical energy from the speaker spikes and from the music as such
This energy likes to enter the rack through the feets =>
Feets of Rack and feets of speakers need to be harmonized to have proper energy management.
2. Air: The air transports a lot of mechanical energy, this will go into the rack structure as such, into the individual levels and legs , which can than effect the gear to placed onto the rack =>
Effective Energy management for every level and the structure is needed.
3. Air: The Energy transported from the Air will make the units placed on the Rack resonating =>
The Rack should absorb this energy
4. EMV: The units to be placed in the Rack will effect each other with an EM field, also the room will have some EM fields. => EMV protection should be part of the Rack concept (like grounding)
5.PSU vibration: Any Psu vibrates, sometimes so strong, that this vibration might effect other gear as well =>
The rack /platforms/feets should absorb any vibration coming from the gear placed
When I start to decide, which Rack might be the best, I look into this 5 areas and analyze, if this rack might fit into my room and my situation.
So I just decided to go for an Artesania Rack, as the Rack can be customized with different feets and isolation accessories to nearly any given situation. They even recommend different coupling for rooms with a high level of acoustical energy (like normal living rooms) and for rooms with a high level of acoustical treatment (like studio)
I have not yet the experience , but I will find out soon.
Another reason it, that Nishikawa is using Artesania and my AF3P es developed/voiced on Artesania.
Most of my gear is currently placed on the HRS S series rack with M3x platforms.
The Artesania Rack will be for AF3P (Top-level) , the Boulder 2008 Phonopre (2 level) and my 2x MC step up transformers (one level), the AF3P airpump will be placed separately.
