Абе не е баш ЦД, а и на всичкото отгоре това мастерирано специално за това издание.

How then to ensure that audiophiles who have been faithfully supporting the HUGO Label can enjoy the highest level of sonic fidelity? Having identified the digital distortion problem of CD, Mr Aik has focused his research of the LPCD in the following two parameters:
1. LPCD mastering
Applying HUGO's proprietary sonic spectrum processing software system on the following procedures:
(a) Using the highest specifications to convert the original analogue master tape into a digital format;
(b) Up sampling the original digital master to the highest specifications. Thereafter, adjust the tonal density, dynamic range, bandwidth, etc., using a highly precise digital processing system. Finally the digital master is encoded into a 16 bit/44.1KHz CD format. Throughout the entire digital processing, the digital system is operating in an optimal configuration with the highest purity of the AC power supply and a highly precise, military-grade digital clock. All the equipment used was protected by a proprietary anti-vibration system to ensure that all the components and the production process are free of distortion.
Although the top-notch equipment can effectively benefit the mastering production, mastering process is still very much a complex manual project which requires the mastering engineers to apply their skill and artistry meticulously at each step of the process. It is therefore not just a simple technical "transfer" from one medium to another. It is hardly surprising that the mastering of a LPCD takes a labourers 20 studio hours!
2. LPCD Production
The primary objective is to minimize the signal distortion of the digital laser reading system embedded in the CD player, and the "over-correction" by the signal correction system. In addition, a specially treated material is used to eliminate the diversion of the laser beam; thereby improving the accuracy of the laser output signal, enhancing the stability of the disc rotation, reducing the rumple and flutter rate. All of these help to reduce the pressures on the CD servo-system which otherwise can generate signal loss and distortion.
After numerous experimentations, the above process is finally adopted to produce the LPCD. What is presented to audiophiles is a disc which is many times more precise than the ordinary disc. Very fine artistry is put into the stamping / pressing processes as well as the digital format change processes to eliminate any significant noise intrusion. Special material is also used to help preserve and enhance the durability of the LPCD.
Hugo Productions not only produces its own LPCDs, it also provides the technical expertise to other companies or producers to manufacture the LPCDs on the premise that the recordings qualities are of the highest level.
LPCD products are classified into two categories, i.e. LPCD33 and LPCD45. LPCD33 is a specially manufactured CD product whereas LPCD45 is the top-of-the-line audiophile master product that is built on the best CDR master specification. Consumers need to ascertain whether their CD players could playback the CDR before they purchase the LPCD45 discs.
Now, there is no need for audiophiles to slave over their LP players. Audiophiles also need not be tortured by the noise and wow and flutter of the LP and yet still able to enjoy the highest sonic quality equivalent to an LP system. Come and enjoy the wonder of music and sound effects brought to you by LPCD
