The following is a quote from page 5 of the Klout owner's manual:
"Up to five KLOUTs can be stacked on top of each other without risk of overheating. We do not recommend stacking the KLOUT on any other product."
The following is a quote from page 9:
"Do not stack a KLOUT with other products which will obstruct the airflow, or which cannot
support the weight."
In addition to the heat issue, it is not good to have power supply components too close to the sensitive electronic circuitry of preamps or processors. Although the Klout has a screened transformer, it's not a good thing to do if you can avoid it.
