3. Unpacking and Placement 

After opening the top cover of the box, remove the upper layer of hard foam material. 
You can then lift the Preamplifier from its box cradling it with the cloth that is 
underneath the chassis.  Retain the cloth and all packing materials for future use. 

The Absolare Preamplifier is designed to be supported by separate support feet. 
They do not have support feet fixed in place. Feet can affect the sound quality 
significantly. Feet must be positioned underneath each unit in direct contact with the 
aluminum base plate 

– not the leather clad MDF covers. There are three areas 

where the aluminum base plate is exposed through openings in the leather clad MDF 
bottom plate. You can use either three or four feet.  

After the Preamplifier has been placed in its final position, it can be lifted in turn to 
locate the support feet 

– firstly lifting the back (for 2 feet) and then the front (for 1 or 

2 feet) to be placed underneath the chassis.  Adjusting their position will also affect 
the sound to varying degrees, depending on the type of rack, location or interaction 
with other equipment. For the most situations, the arrangement as shown in the 
diagram below is a good starting point.
