My opinion is:
For a company that claims "better sound through research", they dispute all standard measurement methodologies and does not publish their own, and therefore all of their claims are subjective and remains unsubstantiated.
This is their original reason for doing psychoacoustic based engineering "research":
"Bose's first loudspeaker product, the model 2201,[13] dispersed 22 small mid-range speakers over an eighth of a sphere. It was designed to be located in the corner of a room, using reflections off the walls to increase the apparent size of the room. An electronic equalizer was used to flatten the frequency spectrum of this system. The results of listening tests were disappointing.[13]
After this research Amar Bose came to the conclusion that imperfect knowledge of psychoacoustics limits the ability to adequately characterize quantitatively any two arbitrary sounds that are perceived differently, and to adequately characterize and quantify all aspects of perceived quality. He believes, for example, that distortion is much overrated as a factor in perceived quality in the complex sounds that comprise music. Similarly, he does not find measurable relevance to perceived quality in other easily measured parameters of loudspeakers and electronics, and therefore does not publish those specifications for Bose products. The ultimate test, Bose insists, is the listener's perception of audible quality (or lack of it) and his or her own preferences.[14][15] This reluctance to publish information is due to Bose's rejection of these measurements in favour of "more meaningful measurement and evaluation procedures".[16]"
That the fact Bose disputes all standard methodologies in measurement and quantification theory, they can't engineer using any available science to form a meaningful feedback between psychoacoustic model research (understanding human hearing) and electromechanical research, because they dispute all electromechanical research on measurement thus far applied to sound.
This is what is said of Amar Bose: "Amar Bose believes that traditional measures of audio equipment are not relevant to perceived audio quality and therefore does not publish those specifications for Bose products".
Notice that he categorizes audio perception and thus reproduction as a "belief". It is no wonder why he doesn't have to substantiate any claim, and can sell you a "belief". Worship him and his cult.
Lastly, recording studios and sound engineers all produce according to measurement. All studio equipment (mixers, DACs, sound monitors, headphones, etc, etc) are ALL rigorously tested and measured to SPECIFICATION. If Bose intends to reproduce faithfully the original sound as intended, then they necessarily MUST have some measure of their own equipment for the public to compare. However, seeing as so much of their desired sound (Wave radio for example) is achieved through DSP processing (read "psychoacoustic processing"), no wonder why they are left out of the bit-perfect, objectively measured, audiophile crowd.
Then you have the REAL pioneers in the audio industry, from the enormously successful Centrance, who developed the DACport and licenses their firmware code to other big names like Bel Canto, Benchmark and Lavry (just to name a few). A product that sounds good (subjectively MOST Of the time) and measures sublimely.
Then there is the smaller, DIY names like NwAvGuy, who developed the O2 amplifier and ODAC, showing once and for all, that an objectively designed, well engineered audio product can compete with much more expensive products with weaker designs. I'm sure many of MacRumors readers are familiar with Centrance, Benchmark, Bel Canto and the minute budget O2 and ODAC.
To give credit where credit is clearly due, BOSE HAS been able to make low level, casual entertainment listening a joy for many. And where audiophile-like precision is not required, psychoacoustic processing can be interesting to the listener when it is not distracting. However, to be FAIR to other pioneers, there were LOTS of psychoacoustic models that did different things like "Q-Sound, A3D (which was awesome), Virtual Dolby, SRS3D and SRS WOW, etc, etc". But don't for a single minute confuse Bose with Pro Audio quality, or even Hi-Fi.
