    I used to have that and I gave it away, or threw away, in my home purge last year. Anyway, that was their TOTL AVR with digital amps. If you can, find the Sony 9100ES DVD/SACD player, and use their proprietary Ilink digital system to connect them together. You will have an excellent surround sound system if you do. I also purged the 9100ES last year. LOL.
