Design of the NAD T757 Receiver
Out of the box, NAD's T 757 has the core features required to make a modern centerpiece to your home theater. The NAD offers 60 watts of power for each of its 7 channels. This is rated with all 7 channels simultaneously driven from 20Hz-20kHz at rated distortion. This is an honest power rating versus claimed 100 watt per channel receivers selling for a few hundred bucks. Even better, if you use 5 channels for your surround system you can repurpose two of those amplifier channels to bi-amp your main left and right speakers (perfect of my Infinity Betas Towers).
These channels of amplification can be fed by a traditional AM/FM radio from the built in tuner. Or as many of you will, the T 757 offers an array of analog (3) and digital (6) audio inputs that can decode the various surround formats available from traditional Dolby Surround to the latest Dolby True HD and DTS Master Audio (and everything in between).
For video (Audio and Video for HDMI), NAD's T 757 has composite (2), s- video (1), component (3), and HDMI (4) inputs. The HDMI inputs are version 1.4 which includes 3D support. The T 757 will cross-convert the legacy video connections to HDMI to allow you to run a single HDMI cable versus a bundle of video options making your hook up life easier. However, the receiver does not process or up convert the video to a single output resolution for these legacy analog or digital signals.
One of the things NAD is very proud of is the upgrade path provided on this receiver. It seems like they have taken a page from the higher end of the world of personal computers and have moved components likely to be upgraded to a sub chassis / daughter card. For the PC, this would typically be a high end graphics card. For the NAD, it is the digital audio video section including the ever evolving HDMI connections. NAD calls their technology, Modular Design Construction (MDC). Unlike PCs, to upgrade a NAD receiver you'll be locked into NADs proprietary solution. A visit to a NAD dealer and an NAD estimated $200-$600 will upgrade your receiver to the latest digital standards (Mega Master Pro Super Surround?). This upgrade would include the hardware and any associated firmware required. I've discovered NAD also has the ability to upgrade the firmware separately as my unit was upgraded during my review cycle. Contact your NAD dealer for more information.
How valuable this MDC will be to you is debatable. At $1600, the T 757 is currently the least costly receiver offered by NAD to offer MDC. If the cost of the upgrade creeps closer to $600 I personally would hesitate upgrading the T 757 as the cost of the upgrade approaches half the cost of replacement. At $200 on the other hand an upgrade may make more sense. The higher the price of the piece of gear, the more appealing this feature gets. So as you move to NADs higher priced receivers, MDC becomes even more appealing.
