Remastering process begins with high end player to preciselly reproduce your digital files - through professional custom refurbished tape recorder with master quality tape and with realtime recording to professional dsd recorder.
Reference power and interconnect cables and master quality tape and dsd 1bit 5,6 MHz format dramatically increase music scene with very detailed sound and very natural high and middle frequencies.
Finally 1bit 5,6 MHz dsd files converted to 24bit/192KHz (or other resolution) waves or flacs with special software. Or any other format on demand, including dsdiff or dsf files.
We don't use any software filters and result is pure near analogue sound on digital file.
This is the result of many years of experiments with cables, tapes and devices.
