Here we have the next generation of an all digital receiver which does deliver on the theoretically superior sound quality.
The design is bleeding edge state-of–the-art, and true to form is quite unreliable. That is, most of the samples are defective. But Best Buy has an excellent return policy. So don't buy one if you are itching to whine here.
Out of three, one was good. The first defective sample had a square wave buzz and would shut off. The second had a popping sound in the rear left speaker whenever the disc changed location and removed the audio stream.
I compared it to the latest $349 Denon which had a wide dynamic range and improved openness (compared to previous models) but the soundstage is still too homogenized. (Denon is a great brand name and it pains me to say anything not positive).
The Samsungs PQ was also clearer which indicates their HDMI 1.4 chips are superior. So digital is not just digital, as implementations do matter.
It’s revealing that the high-end press offers zero coverage of a product that establishes a new sonic standard. Perhaps Samsung should raise the price to $5K and start paying to advertise in their publications.
Note: follow the inferior sounding Onkyo/Integra lead

Don't know whose technology is behind this product, but my guess would be TI.
I do not have time to start a new thread.
In summary the model 700 receiver is recommended to those who are curious about hearing new levels sound quality and realize that they will probably need to return it. But if you find a good one then you don’t have to wait until next year!
Note: In my house I’ve got three media rooms so I’m trying experimenting with different types of speakers and displays. I got a good sample and I’m still hoping to get a second.
