1. Nope, you can use a fair number of consumer universal disc players including Oppo, Sony, etc.Ripping an SACD requires a compatible device (Blu-ray player/PS3), network connection, computer, USB thumb drive, and software (which at one point required either command line knowledge or Java be installed on the computer). That's a lot of complexity.
2. Don't most (all?) of us have LANs, computers and thumb drives anyway.
3. I can say that I have no knowledge of Java. I just use a thumb drive with control files I downloaded.
As just noted in another reply, been there, done that and regularly. I challenge you to do that in less time and with fewer keystrokes than it takes me to rip an SACD.By contrast, with a Blu-ray Disc, everything is handled on a computer. All you need is an optical drive that will read Blu-ray, a computer, and software. I'd say the easiest software to use is the MakeMKV/DVD Audio Extractor combo. Use MakeMKV to backup the disc (defeating the copy protection), then use DVD Audio Extractor to rip the desired audio from the backup to your format of choice. Much simpler than an SACD.
