Gateway to professional quality: headphone amplifiers.

[astankov]

Whoaaa....yet another pointless thread.

All your threads are very good in showing unreadable schematics designed 30+ years ago

What do you try to say , ask or show with these threads? I think even you don't know.

Keep up with the good work!

Regards!

New techniques to enhance the audio is not quite good, because they are classic design principles that do not change -I showed the good things and for complete information nothing I have to hide and whether we can be afraid?

Perhaps if you render these designs in LT spice or free drafting program, using modern components, people may read them and consider your views.

What is normally well it is well.
Even from the very god of schemes are not good if they are bad applies.

[Ian Finch]

There is nothing "well" about unobtainable parts, obscure drawings or guitar effects
in headphone amplifiers.

We can only comment on what we see. The glory of 1970s audio engineering
does not travel by internet, so we must see how it differs from what we consider
the best possible for us in 2012. We don't rely on hard-wire assembly any more,
so there is little but schematic diagrams to compare.

To appreciate anything abstract, we must compare, so drafting schematics in
standard format or spice programs helps to do this for everyone.

Who looks for and checks it knows what might be best.
Most people have not learned the power precise application, and appropriate measurements of transistors, for the normal projects.

this is a nonsensical generalization and I dont just mean your electronic translator. your schematics are indecipherable and full of parts that are not available to buy, how do you suppose this is good engineering?

we have headphone amps (in the headphone forum....) that defy the most modern instruments to measure them. maybe true not everything is in the measurements, but we can bet it beats the headphone amp from the 70's when i'm sorry, but the headphone amps were mostly terribly performing afterthoughts. Another thing is, we can bet that your yesteryear schematic was designed for yesteryear's headphones, which were VERY different.

appreciate the effort, but lets face it regurgitating old work without even making the effort to make it legible in today's context to todays engineers/builders/hobbiests; doesnt take that much work

Audio business never use ready-made ​​things produced at the factory.
Therefore, all audio diagrams are not the best and only ridiculously easy to manufacture.
Only small businesses use audio stuff factory production.

Just what!!??
