● Audio masterpiece collection
The joy of audio files is all about listening to famous performances and recordings of famous songs. The analog master tapes of "Historical performances and recordings with eternal value" are stored in record companies all over the world. Stereo Sound has discovered a high-quality master tape from among them, and has started the "Audio Masterpiece Collection" that makes full use of the latest technology to finish the "best sound".

This product is a digitized version of the audio of an analog master tape with almost no processing. Therefore, as a general rule, not only the ultra-low frequency cut, but also the equalizing to make the sound easier to hear and the noise cut and dropout caused by the master tape are not corrected. This is based on a product plan that wants to deliver the sound of a master tape, which could only be heard by a limited number of people involved in production, to the audio file as faithfully as possible.

● "Ideal opera performance that cannot be realized on stage" created by John Culshaw's passion
Decca Records of the United Kingdom conducted a stereo recording project of "Ring" from 1958 to 1965 with the Vienna Philharmonic conducted by Solti and selected Wagner singers.

■ Master tape used for SACD
The master adopted for SACD is an emergency safety analog master tape excavated from the tape storage by Universal Music. It was provided by Decca in the UK in the 1970s to King Records, the original importer at the time, and was literally 1/4 in case the metal master for LP record press was defective. It was made by one-on-one dubbing from an original analog master tape of width. However, because it was for emergency use, its whereabouts were not recorded today, and it was also called a phantom. It was finally discovered after an investigation that could be called the obsession of Japanese universal music, and we were able to obtain official permission for SACD from Decca's home country.

Currently, Decca's home country is mastering the "Der Ring des Nibelungen", commonly known as "James Rock Remaster", a digital master (PCM) that has been noise-cut and equalized by engineer James Rock. .. Digital discs and digital files officially released after 1997 are all without one exception, as the original analog master tapes are not ready for use due to their damage (it is said).・ It is based on Rock Remaster. Therefore, this work will be the world's first and only SACD that has been digitized based on the precious master sound source before this remastering process is applied.

■ DSD by flat transfer
It was the mastering studio in Nippon Columbia that did the digitization work for SACD. The audio of the analog master tape played by the A820 deck of the Studer carefully adjusted by Mr. Shigeru Takezawa, a master of Japan, was converted to a 2.8MHz DSD signal (SACD digital standard) by flat transfer. The equipment used for DSD is the Pyramix system of Marging Technologies. Strict clock management using Esoteric's master clock generator G01X, tuning of the entire system including digital / analog cables, AC cords, etc., to faithfully convert the audio of the analog master tape to DSD.
