To be fair, Sony is good at the technologies they invented; they didn't invent the audio amplifier. They did invent the stuff I mentioned, either alone or in partnerdhip with Phillips. SACD is a failed format, market penetration wise. It did not take over from CD and had the bad luck of coming along shortly before the download revolution. Super DVD died too, but it was abandoned right after release because Sony's Blu-ray showed its dominance immediately. And of course DVD-A failed as well. It lost out to SACD. It's a battlefield out there.
Also, despite getting really beat up lately in the marketplace, Sony is a major player and not a niche manufacture. They have to field a full line of products from entry level on up. They sell, for instance, more headphones than any other company in the World.
Most 5.1 boxes are integrated circuit output pieces. Think of the big companies' offerings as being much more competitivly priced than the boutique stuff. Almost all amps have a jfet front end. At this point I think op amps do it as well or better than discrete. Again more compact, lighter and lower cost.Edited by Clarkmc2 - 7/9/12 at 11:21pm
