Well that alone justifies a price 4 times that of other 2.0 players right?
Good luck with that NAD.
What's with all the bias towards higher priced electronics? In this case, the audio section on the NAD Blu-Ray player will be of far higher quality than that on a mass-market player. For instance, the multichannel output of a good BD player such as the Denon 3800 sounds better than using its HDMI output with just about any mass market receiver, and the same will be said of the NAD player.
I would expect better DAC, better circuitry, lower noise power supply, less vibration, better quality control and higher build quality, plus unlike mass-market products this isn't intended to be replaced every 3 years.
Also keep in mind that someone who has already spent $5,000 on NAD separates will likely want a NAD Blu-Ray player to match their system, and in relation to their existing pre-amp and poweramp this product will offer value at this purchase price. I can assure you this product will sell very well in this niche market, its not intended for mass production.
PS - Denon just announced a new DVD-A1UD Blu-Ray Player for $5,860. Keeping in mind that the old DVD-5910 ($3,500) is arguably the best DVD player ever made, I can assure you this will sell well to a specific market, while allowing Denon to show off advances in this technology. In relation, the NAD is a bargain
