What music does an amplifier designer use to evaluate amps?

Legendary amplifier designer, David Berning, discusses the music he uses to test and evaluate hifi audio amplifier designs.
Among other recommendations, David makes a case for using "challenging" music when testing amplifiers (or speakers or any other hifi component). Watch the video to learn the reason why he recommends this.

Meshuggah bleed. But now it's phantoms

I always rely on a high quality recording of a full symphony orchestra playing John Cage's 4 minutes 33 seconds.

😂

First and foremost will always be orchestral music, then violin, cello, and piano concertos. Next, I want male and female solo vocalists and then after that "folk" - acoustic guitars, stand-up bass, and then lastly Rock!

How are things going with the DAC?

[@michaellichnovsky8397]

It’s on the website!

[@johnratcliffe6438]

@michaellichnovsky8397 I know. I am waiting for completed images, as opposed to renders. Some reviews from well regarded people like Golden Sound would be good too. I am well past throwing thousands of pounds at components and hoping for the best.

[@LinearTubeAudio]

Thanks for the interest, John. We will post more information on the website when we have it. We will be sending out units to reviewers, once we have production units with which to do so.

the image is WAY too dark...

[@LinearTubeAudio]

Apologies for the video quality; we messed up the settings in the camera. We’re an audio company after all. :) Luckily, the video quality doesn’t make it any harder to hear what David is saying, which is the real value of this content.

[@AlainCliche]

@@LinearTubeAudio I understand and though the same.but let me remind you that perception is utterly important... I've read so many GOOD thing about your products and this "technical problem" was a turn of...

[@LinearTubeAudio]

Understood. Thanks for the feedback. Rest assured the person behind the camera is not the person who designs and builds our amps. :) We discovered the issue after the recording and did our best to improve it in post. Ultimately we felt the content was the most important part and decided to publish the videos.

[@videocast3655]

sounds like you would have to buy or rent or whatever several different cables to see if you can maybe hear which one matches your system best. I think NOT !!

[@jasonbuhagiar2997]

This video had terrible sound quality itself.

[@LinearTubeAudio]

Thank you for the feedback. What specifically about the sound quality did you find objectionable? This will help us improve future videos.
