What a POS! I saw that a few months ago, and about puked! Tubes, my ass. I design professional audio equipment. With the possible exception of musical instrument amplification, the only reason for using tubes for audio products is because people will spend their money for them.
What people "like" in tube gear is NOT accuracy, it's a pleasing coloration. It's a cute massage, but it bears little relation to the sound intended by the producer of your favorite recordings. Honest, I know what they use to record and monitor them in a pro environment.
Of course, that's before you get to the problems you invite by putting a very hot tube inside a computer and genereate some really high voltages to run the noisey beast. Tubes in computer audio are a really stupid engineering choice.
Of course, that's before you get to the fact that, contrary to the statement on their page, Edison did NOT invent the vacuum tube. The tube was based upon Thomas Edison's 1883 discovery in his early lamp of an unexplained electric current that flowed across a gap from the filament to a metal plate. In 1904 an English inventor, John Ambrose Fleming, had shown that this effect could be used as a wireless receiver, two years later Lee deForest added a vital element, a wire grid between the filament and plate that controlled this current flow.

What audio equipment do you design? I just thought this was interesting since its a courageous approach by Aopen to implement a tube amplifier. I listen to a lot of music with instruments so the harmonics it produces makes the sound more appealing than a typical class ab
I was Chief Engineer of Aphex Systems in the early 80's. In 1978, a partner and I invented the VCA (Voltage Controlled Amplifier) circuit that is still the centerpiece of their analog compressors, expanders, gates, etc. I've designed a lot of other products, as well, including tube a tube compressor and some mic head amps for Groove Tubes.
Check out this discussion on that notion. Pay particular attention to the dude named Mobius- he knows what hes talking about.
My opinion? Mobiius is more full of himself then of any knowledge. But, he's talking about stuff in the early 80's, i was in diapers then, I dont know ho wmuch stuff has changed. Speakers are probably the #1 most important part of a system, although every piece in one way or another does make a difference.
As for amps? Ultimately, if you bypass the processing features (Which an amp SHOULDNT have anyways!!), ALL amps sound the same IF ran within spec. (we're talking electronic, not tube). Tube amps are kinda their own field.
Basically, people who preach 'OH CABLES! OH TUBES!" are just stuck on how much they spent on their equipmebnt, and want to justify their expenditures. Also, these people disgust me.
"Oh, my reciever has a mediium grey sound vs the white sound of THAT reciever"....Oh gee, I HATE it when I have medium grey sound....

If you read the page again, Harvey, it did NOT say Edison invented the vacuum tube. It said, "adoption of an idea that was spawned by the invention of the electric light bulb by Thomas A. Edison back in 1879 - the vacuum tube."
The hint there is the word spawned......meaning the idea came from Edison's invention of the light bulb. Nowhere does it say Edison invented the vacuum tube.

Try doing a search for an IEEE article comparing tubes and semiconductors. They did more than just break out thier ears, they broke out spectrum analyzers and looked at the difference from an electrical standpoint.
...and although those disks aren't vinyl, they do look neat 🙂
Edit: READ THIS and make sure you click the links inside. (particularly "Distortion under test")
