The Downside
The Onkyo TX-NR905 was not without its faults.  One of these might be insurmountable for some potential purchasers.  Thermal management for the heat that is produced by the TX-NR905 will be difficult to control for those who desire or require that their equipment be placed in a restricted area behind closed doors.  Although this multi-channel receiver has been engineered to operate at higher temperatures, other associated components quite possibly have not, and may malfunction if the ambient temperature in which they operate becomes too high.  I would highly recommend placing the TX-NR905 outside of any restricted space, but if it is to be installed in an enclosed cabinet, appropriate ventilation should be incorporated.  Please be aware that simply placing a fan by the unit without having sufficient air exchanges will not reduce the temperature within the enclosed equipment area.

As with many newer electronic devices using HDMI interconnections between various components, the Onkyo TX-NR905 did have some synchronization problems at times.  I was unable to identify the exact cause of the issue, which prompted a call to Onkyo technical support.  After I was given directions to reboot the TX-NR905, the unit worked within specifications and I had very few problems getting all of my HDMI-equipped components to interface correctly. 

Unfortunately, I had other set-up questions that required additional communications with Onkyo’s technical support department.  My next four efforts were less than successful.  After being left on hold, which varied from 40 minutes to over an hour, I was finally able to speak with a representative, first providing my name and call-back telephone number, and begin to discuss the issue.  Within a few brief moments, I was disconnected, and subsequently never did receive a single return call from Onkyo's technical support.  This experience proved to be extremely frustrating, and I was required to use methods other than Onkyo’s customer support to acquire the information necessary to rectify the issues.

Technology is continually moving along at a blistering exponential pace, a trend first formalized as Moore’s Law more than three decades ago.  To a large extent, this is responsible for the seemingly prevalent conclusion found in many equipment reviews praising the performance-to-cost benefits of numerous components.  With that acknowledgment, it is extremely easy to appreciate and admire the technological advancements, along with the sophisticated components Onkyo has incorporated into the TX-NR905.

As I look around my home, it is literally littered with dated or functionally obsolete audio video equipment, which I've accumulated over the years, with several pieces costing considerably more than the TX-NR905.  These include surround sound processors, video processors, room correction components, electronic crossovers and individual amplifiers (two-channel and seven-channel), just to name a few.  Without question, the TX-NR905 surpasses the performance of most if not all of these individual pieces at a fraction of the cost in a single component.  Sit down and do the math, and it becomes obvious why the TX-NR905 with its accompanying feature set at its asking price is an outstanding value.

Onkyo has provided an extremely sophisticated audio/video component with numerous advanced processing features.  It is extremely versatile and has abundant power to be the foundation piece of a truly high-end home theater and audio system.  Although not without its shortcomings, and complex by nature of its flexibility, Onkyo still sets a new benchmark for quality and performance, challenging most audio/video receivers anywhere close to its price point.  With its well-groomed aesthetics and solid build quality, incorporation of state-of-the-art audio and video processing, and most of all excellent global performance, it provides an exceptional value.  The Onkyo TX-NR905 undoubtedly will be pursued by a wide customer base that is looking for a formidable receiver as the anchor for a compelling, exhilarating reference home theater system.
