OVERVIEW

The circuitry used in the P3100 is the latest refinement of our trans•nova (TRANSconductance Nodal Voltage Amplifier, US Patent 

4,467,288) circuit. It has been proven to offer sound quality to satisfy the most analytic audiophile or the most demanding professional. 

The  natural  sound  and  realistic  reproduction  have  made  trans•nova  amplifiers  preferred  in  many  critical  installations.  Since  the 

pioneering use of lateral MOSFETs in the DH-200 amplifier, they have proven extremely fault tolerant even in abusive situations. This 

sturdiness enables the amplifier to drive reactive speaker loads without the performance and sound penalties imposed by elaborate 

protection  schemes.  Passive  cooling  with  large  heatsinks  allow  for  low  mechanical  noise,  and  special  care  was  taken  to  reduce 

noise and distortion at every possible stage. The high performance specifications of the P3100 means that it is equally at home in a 

recording or mastering studio as it is in an audiophile listening room. 

Recording Studio

Hafler  has  a  long  history  of  use  in 

professional recording studios with 

unparalleled sound quality and 

reliability.

Two Channel Listening

The  P3100  delivers  rich  detail  and 

highly  linear  amplification  for  the 

discerning audiophile’s listening room.

Mastering Studio

Trusted by the ‘golden ears’ of the 

recording industry, two bridged-mono 

P3100s  provide  incredible  headroom 

and quality for use in a mastering 

studio.
