Introduction
Congratulations on purchasing the HALCRO™ dm10 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 amplifiers, 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.
ELECTRONIC DESIGN
By Bruce Candy
In keeping with my philosophy of design, my basic aim was to produce a
preamplifier with which I, personally, am quite satisfied. I sincerely hope that
others will share my satisfaction with these products.
As I saw it, the major issues were:
Ÿ Zero compromise on Transparency.
Ÿ Flexibility.
Ÿ Ease of use.
Ÿ Progressive design concepts.
