Has Class D amps made Class A/B completely obsolete for audio? I find it exceedingly hard to believe the claims that A/B sounds different/better than D in a DBT when all of them are competently designed for transparency and working within normal parameters.

They list a benefit of ethernet as "bit-perfect communication" -- but then start saying how theirs is better because

"Extremely high-purity Perfect-Surface Silver minimizes distortion caused by the grain boundaries"

"eliminating harshness and greatly increasing clarity"

That's not to say that serious pro audio can't be super expensive, too:



The cost of just the speakers in that setup is around $105,000, never mind the probably insane price for that mixing desk. I'm sure it sounds better than any audiophile setup ever, though. And it's not over half a million dollars like those Living Voice monstrosities.

Other than edge cases like that, I noticed pro-audio monitors tend to be very reasonably priced for the level of sound quality for some weird reason.

You gotta love DBT haters and their hilarious arguments against DBTs:


1. Attack the methodology, crappily - DBTs due to inherent real-life limitations is less reliable then their own sighted judgement "because a DBT can't be perfect"

2. Claims an obvious difference in sound with X product, while putting the burden of proof on skeptics who says it's bullshit.


I strongly suspect why they hate the idea of blind testing so much is that deep down at some level they know they will be proven wrong conclusively and their worldview will no longer hold water like religious fanatics.

Somewhat related to the discussion going on, a bunch of audio manufacturers chime in on whether or not measurements can accurately predict the sound of a component: http://www.herronaudio.com/images/Measurements.pdf

I thought it was an interesting read.

tl:dr, but I fail to see how one can remotely argue against that objective measurements can't be used to judge sound quality.

For a long time video card benchmarks are only posted as min/max/average frame rates, yet people started to feel that X model feels jerkier or sluggish than Y model despite having similar frame rates, the subjective differences are later confirmed by a new measurements of frame-time analysis.

In that Dave Grohl documentary Sound City, Neil Young actually said on camera that the people who made up the digital sampling process made a mistake, so all digital recordings since then are inherently flawed. Of course he didn't actually go into any details of how or why.

The best tube amp is still the AOpen AX4B.
A motherboard with a built in tube amp. So your fully digitally source can be amplified by analogue means in probably the most RF noisy place in your house.

For some reason it never caught on.



In addition to RF noise, imagine the tube microphonics with the 3+ fans, a spinning HDD and an optical drive in a typical PC. What can possibly go wrong?

High voltage won't do anything, apart from being a major safety hazard.

To really warm up the sound, you need amperage, and lots of it. Normal 18AWG lamp cord is rated to carry 13A, and thicker cable will obviously be able to carry more.

I figure you should start out with a "low burn" at 20A, just to get things going. Then increase gradually in steps of 5A until your house burns down sufficient warmth has been achieved.

And it has to be DC, because that actually makes electrons flow in one direction. AC would just make them oscillate in the same position which makes the soundstage static.

Agreed.

While I'm here, I don't know if this is totally ignorant but: wouldn't the easiest way to test a system be to put a couple high quality mics/sound recorders right at the position of your ears in your listening room, play a track, and then compare the hi-fi recording's waveform to the one that started out in the system? I doubt it would ever be a 100% match just due to acoustics but if they're going for absolute fidelity, and feeling like you're right there next to Roger Waters and Syd Barret in the studio, it seems to this know-nothing layman like that would be the scientific way to approach it?

You don't understand, we have the capability to make 14nm CPUs, 40 terabits/s fiber optics across the Atlantic but not audio testing equipment that are objectively better than our ears.

I did just realize a lot of modern subs use class D amps which are anathema to audiophiles since they undoubtedly sound like computer chips, though. Someone needs to make a tube-powered sub [assuming one doesn't inevitably already exist].

Class D amps are a perfect fit for subs because the potential problems with high frequency distortion of Class D are bypassed entirely, power efficiency is way beyond Class A or AB and the distortion of the sub transducer alone dwarfs the amp by magnitudes. Using tubes to drive subs is the most clinically retarded thing anybody can do, although the lack of basic intelligence to understand basic engineering principles is a proud trait of audiofool circles soooo...
