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.

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.

Chill Callahan posted: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 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.

Combat Pretzel posted:One might argue that the driver of the display may cause interferences with the audio circuit, given the high frequencies it'll run at. Then again, not a problem a piece of metal foil wouldn't fix. Well, smartphones like iPhones and Galaxy Notes also happen to have some of the cleanest analog outputs to date, despite the magnitudes higher in engineering complexity. Like our venerable NwAvGuy once said, the notion that some guy in his basement can make a better audio device than companies having billions in resources, skill and testing equipment just because the latter uses utterly cheap parts is thoroughly absurd.

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...

And no PWM power for any of the fans either, heck it's better just take out the CPU fan completely then Prime95 the CPU to 100C to bring out the warmth in the sound.

Not just limited to placebophiles, there's a Chinese saying of "A cent spent is an additional cent of quality received" which is great advice to subscribe to if you like getting ripped off left and right. I really don't get the logic of how people think a cheapass product is surely going to suck but others that cost hundreds or even thousands times more to do the same job will not. "Surely the expensive stuff is better is always because the seller put more actual well thought effort into it, and never because the seller is trying to rip me off!"

Yours sounds like it is one of those, because on a non-affected handset there's no noise at all.
