[TOS #5] From: Why do people use AVRs for stereo?

Lemme get this straight.

We have dirt cheap GPS receivers that can get a position lock in like 5 seconds at timekeeping accurate to nanoseconds with GPS signals at a strength of 0.000,000,000,000,00016 W and somebody is telling me a mere AV receiver couldn't be audibly transparent because?

I am of the opinion that AVR designers and manufacturers don't need to place as much emphasis on the audio aspect as do audio only designers/manufacturers.


I once got to assist a tiny but well-regarded high end kit manufacturer for awhile, and it was sort of eye-opening: The boss went on record saying that with his new amplifier, upgrading the power supply capacitors wouldn't make any sonic improvement and that the cheaper solid state power supply rectifiers were best. And guess what happened? Customers insisted on Rubycon Black Gate capacitors (then the audiophile capacitor du jour), while the tube rectifier option proved popular!


Two words: Sighted evaluations.

And this in a nutshell is what I think has become of the specialist high-end audio market: High end audiophiles want what they want, and if there's sufficient demand, a manufacturer that wants to survive in the business will produce it whether it makes sense to them or not. Prices tend to be high partly because this market is small, but also because the customer base won't take it seriously if it doesn't cost enough.


One counterpoint is that high end audiophiles don't get what they want because they as a rule actually don't know what they want.  To understand the high end audio market first understand the fashion jewelry market.

To more mainstream companies like Denon/Marantz and Yamaha, the challenge of high-quality amplification was solved decades ago, and aside from an occasional boutique product, it's mostly about features and lifestyle marketing these days.


Their most serious problem is staying alive while their market shrinks because it is dying off. Reality is that in the mainstream there are a lot of people who think they are high end audiophiles because they own Bose. You know better and I know better but we are a tiny dying minority.

Modern technology is so good that a $39 mass market digital music player has performance that is sonically the same or better than a megabuck high end 2 channel system, except that it is based on headphones/earphones instead of loudspeakers, and for most of the market that is a good thing.

Yes, because as we all know, sound is very very complicated indeed. In fact, it is so complicated that science cannot fully explain it! Compared to landing a rover on Mars, reliably playing back the audible spectrum with any kind of accuracy is insurmountable 

The best part about the "measurements are useless" crowd is the implication that there are no microphones nor electronics in existence sensitive enough to pick up all the intricacies and nuance of music recorded with microphones and electronics.

LOL! Great irony!

They also ignore the very fundamental idea that if you have a two-dimensional signal and handle it essentially perfectly in both dimensions it doesn't matter what you know or don't know about the message it contains.

Does an amplifier need to be able to do speech-to-text recognition to properly reproduce speech?  That is the essence of their argument.

Anything before speakers in the consumer audio market can be built for dirt cheap and yet still be completely transparent. The silicon industry has already done all the hard work for the DAC and Class D amp chips and are selling like $1 per piece. Even for a SQ bottleneck like speakers you are entering well into diminishing returns territory at $300/pair.

I can't imagine somebody in another industry like Asus making $1000+ PC motherboards, make outrageous claims that they make you more skilled at gaming while getting away with it like in placebophilia land. Their reputation will get ripped to shreds in seconds by the PC enthusiast crowd. Even I think their current $200+ offerings are grossly overpriced.

I remember how the KillerNIC network adapter was pretty much torn apart in the gaming press, and that actually had some (marginal) effect. It did offload a small amount of CPU usage to its own processor, which I guess had a small impact when doing 1GBit/s. Nowadays it's completely superfluous, of course.

But compared to the claimed benefits, it was much more cost-effective to just upgrade the CPU instead.

That's because audio is bias and ignorance paradise.

In computing we have some pretty good benchmarks, and smart people with proper education. Also, many review sites are not as corrupt.

That is because the PC market still primarily depends on objective benchmarks.

IMO there were 2 major assaults on objective measures in audio:

(1) J Gordon Holt - Stereophlie

(2) Hank Pearson - The Absolute Sound.

After round two objective measures could only have a fork stuck in them - in the eyes of audiophiles, they were done.

They are still done - almost everything performs so well that objectively measured differences are meaningless. The main exceptions are rooms and speakers and objective measures of them are growing in terms of credibility,
but probably still not yet there.

No, it just needs to make Pink Floyd's DSoM sound completely natural and acoustic.

Actually, Holt did come out in favor of more a more scientific approach to audio:

For the record: I never, ever claimed that measurements don't matter.

[blind] testing does work … it's (still) the only honest kind.


Whether he was so vocal about it during his tenure is another matter. They might not have always had the strongest technical skills, but you gotta hand it to these advertising execs and journalists: They could write pretty persuasively.

In the end, it appears that Holt died without visibly taking it any further.
