2 speaker and home theater are entirely different. You listen differently. HT is a visual experience with potentially a great immersive sound. I don’t listen to my Marantz 11.2 system for the accuracy of the gun shot sound. I do listen to my 2 speaker pass labs system for the accuracy of the piano. HT subs should literally shake you. 2 speaker setups should have subs that extend and melt into the sounds of your front speakers. My surround sound speakers don’t begin to match the quality of my 2 speakers. And they don’t have to. Having a creepy sound behind you doesn’t have to come out of $20k speakers. I love both setups. But HT and 2 speaker are mostly different systems because we listen differently to each setup. To answer your question, I bought the Marantz many years ago because of the 13 channels and the auro 3D. It’s modestly priced and works well.
surround processor?
Where to go? Older Lyngdorf MP50, JBL SDP-55,Arcam AV40.Lexicon MC ( the cheapest)? Love to watch the movies but also listened to 2 channel stereo. Are there a big sound difference in those? Just the general advice please. Will probably look into second hand.
