Introduction 

 
Thank you for choosing the Linar Audio P107, Stereo Preamplifier.  
 
Linar Audio products are the fruit of extensive research and development in the audio field. Linar Audio 
Preamplifiers are designed to provide the world-class performance. 
 
The structure of the P107 is made of a passive volume control at the front end followed by a gain section 
without feedback. The volume control circuit uses mechanical relays with high precision low noise 
resistors to preserve the integrity of the signal.  Mechanical relays have zero ON resistance, infinite OFF 
resistance, almost no capacitance and introduce no distortion. The variation of the volume level may 
occasionally introduces very small “clicks” that are no danger for the loudspeakers. The voltage gain 
section on the P107 is designed with J-FET transistors at the input and MOSFET transistors at the 
output stage, without feedback. The circuitry is fully complementary and fully balanced from input to 
output.  
 
Aesthetically stunning and sonically spectacular, the Linar P107 is a perfect match for your high-end 2 
channel sources. 
 
As with many high-end audio products, your Linar Preamplifier will require a significant break-in period. 
This process may take up to 200 hours of use. 
 
Familiarize yourself with the material contained within this manual prior to using in order to get the full 
benefit of your investment. If you have any uncertainties, contact your Linar Audio dealer. 
 
Given proper use and care, your Linar Audio Preamplifier should provide you with many years of 
exceptional music reproduction and listening pleasure.
