The first expirience of digitizing of vinyl records was started in 2000­-2002.
PIONEER PDR­05 and PDR­555RW CD recorders was used for learning of 44,1/16 standart possibilities.

After the full rearrangement of recorder’s analog components as well as the upgrade of the clock oscillator it was decided to continue experiments aimed at revealing the weak links of the highway in its entirety.

PDR­-05 has not automatic setting of laser power, because all other works was continued with PDR­-555RW.
After the long testing and hearing, records in CD­-RW is more prefer, than standard CD (compared the same records).
For testing we used records of the greatest musicians, such as opera stars, conductors and others.
