Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

I'm not following you!

Where did I say differences not exist? And I never claimed to know the fine art of music.

There are known distortions and their sonic signature can be identified. And those distortions can easily be predicted in simulation today. So if simulation says a 300B has X distortion at said operating points, building the circuit will prove it does. Provided the computer model for the components are accurate and as always they are not perfect. But neither are real components. However the accuracy of the models is very good - especially for an audio amplifier.

An audio amplifer is not a musical instrument. It's job is to amplify an electrical signal. The closer the output signal is the the input signal, the better it is.

Different tubes and components sound different because the react differently to the electrical signal going through them. What else could it be? These differences can be measured. Perhaps not all today, but you would be surprised of how deep we can go with waveform analysis. Again especially in the low audio bandwidth area.

And if by listening you hear something different and describe it. Chances are a good audio design engineer can point to the circuit parameters causing it.

Tell me something: How do you feel about DBT? Do you think that is a valid test for hearing differences in components?
