3. The cessation of the mindset of "the designers are right and the consumer are whacked for criticizing the products"..... I think regardless of rationale, the best designers take all criticism and suggestions seriously, as opposed to blowing it off as "audiophoolery". The more the demands of the audiophile consumer are addressed, the better the advancements in the art will be. The accompanying and annoying snake-oil products notwithstanding.2. The eradication of RFI in digital playback and in our power grids. I think this is the single biggest cause of unsatisfactory sound in audio today. The problem is too many people either are unaware of the RFI problem or think it's a "figment of wacko audiophiles' imagination". But from my perspective, I really think the digitization of audio has altered not only the perception of the sound, but has even scrambled how people perceive the performances themselves!! I think it has played a role in the ridicule of 1960's and 1970's music that was once popular. (And may be largely responsible for the decline in music- See #1.) And personally, I think digitization has neutered some of the great orchestral recordings, be it Szell's Strauss, Karajan's Wagner, or Furtwangler's Beethoven. Not to mention John Coltrane, Frank Sinatra, Emerson, Lake, and Palmer, and the Doors. I remember how this music once sounded, and it seems like no matter how hard I try, I cannot get that old sound back.
How can RFI be eradicated or minimized? If I was to design a DAC or CD/DVDA/SACD player, it would have the following design parameters:
- As few digital chips as possible.
- As low power operation as possible in the digital circuitry.
- Preferably 20-bit 4x oversampled digital filtering (CD and MP3 playback only).
- A Lanczos3 or other "time-resolute" digital filter convolution algorithm (CD and MP3 playback only).
- Digital components, analog circuitry, and power supplies all isolated from each other.
- Transformer-coupled outputs.
- No asynchronous sample-rate conversion of any kind.
- Optical isolation between transport and DAC (even in a one-box player).1. Re-educating our youth on the fundamentals of music. If the trends in music don't return to the way it was before 1985, once the final generation who appreciated popular music before 1985 die off, there will be so few who are interested in quality sound reproduction, the high-end audio industry will implode. And I think the re-establishment of curricula covering music theory and appreciation in our schools may be the key to fixing the problem.
