IT IS YOURS! 

 

Thank you for selecting 

Lab12 mighty

, a really audiophile Class A power amplifier. Every component on 

it  is  designed to provide  smooth  and  untreated sound.  Mighty  is  a  full  tube  amplifier  with 6n1p  NOS 
Russian  driver  tubes  and  EL34  Russian  on  power  stage.  Mighty  can  cooperate  gratefully  with  any 
preamplifier on the market and it is the perfect match for Lab12 true or hpa. Mighty has the ability to 
nail  you  down  on  your  couch  and  make  you  listen  all  your  music  collection  again.  All  the  power  you 
need for a normal range pair of speakers is here, but the most remarkable point is that you will receive 
a  fluid,  wide  and  addictive  consonant  sound  with  any  choice  of  music  style.   All  components  are 
carefully  chosen  after  hours  of  listening  and  testing,  while  paying  great  attention  to  every  detail 
affecting the outcome. As every Lab12 device, mighty has an ultra-solid construction with glass blasting 
anodized finishing and retro analogue V/U meters. 

Do  not  forget  that  your  mighty  is  totally  handcrafted  with  perfectly  matched  parts  of  the  finest 
selections. In order to reach the optimal performance, your mighty needs at least 150 hours of listening. 
In this time 

all components go from “burn in” period to stable.
