Introduction 

 

Congratulations on purchasing the HALCRO™  dm8 preamplifier. 

 

It  has  taken  two  years  and  the  generous  contributions  of leading reviewers, 

distributors  and  dealers  from  around  the  world  to  design,  then  create,  the 

HALCRO™      preamplifiers.    We  are  confident  that  this  combination  of 

expertise, along with the know-how of the high-end audio industry’s leading 

Research  and  Development  team  will  ensure  the  success  of  the  HALCRO™   

preamplifiers. 

 

The  brief  given  to  our  R&D  team,  headed  by  Bruce  Candy,  was  to  produce 

two models of preamplifier to satisfy the needs of every audio connoisseur: 

Ÿ 

Lowest distortion specifications of any preamplifier in the world. 

Ÿ 

Physical dimensions to suit a standard domestic equipment rack, while 

retaining the stunning HALCRO™   industrial design signature. 

Ÿ 

Tractable controls. 

Ÿ 

Superior reliability. 

Ÿ 

Innovation in design. 

 

The HALCRO™   dm8 & dm10 preamplifiers will add no colorations to the 

music.  When  used  in  conjunction  with  HALCRO™      power  amplifier(s),  all 

you will hear is the original recording reproduced the way the artist intended 

it  to  sound.  No  transistor  or  valve-added  sounds  are  present,  just  a  level  of 

musical purity that was thought impossible until now.
