IT IS YOURS! 

 

Thank  you  for  selecting  Lab12  suono,  an audiophile  Class  A  power  amplifier. Every component on  it  is 
designed to provide smooth and untreated sound. It is a full tube amplifier with 6n2p NOS Russian driver 
tubes and KT150 on power stage. Suono can cooperate gratefully with any preamplifier on the market 
and  it  is  the perfect  match  for  Lab12 pre1.  Suono  has the  ability to  nail  you  down  on  your  couch  and 
make  you  listen  all  your  music  collection  again.  Full  power  for  your  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,  suono  has  an  ultra-solid 
construction with glass blasting anodized finishing and retro analogue V/U meters. 

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

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

  

Before  setting  up  your  new  suono,  we  encourage  you  to  thoroughly  read  this  manual  to  properly 
acquaint yourself with its features. We love music and audio devices and we have built your new device 
with emotion and personal treatment.
