Check out this review of the balanced β22:

pretty good review. congrats

but why is he complaining about having a flat freq response? I don't get it! he wants 'effects' from an amp? does he know what he's reviewing?

he should have done quant. tests and showed the graph results. then let him talk of lack of 'sizzle' all he wants and the rest of us can look at the graphs and decide for ourselves

I also found it a bit odd that he was complaining about the flat frequency response... in my mind the headphones and the music itself should be the only things adding "flavor."

It's obvious the problem with the amp he had was that the power cables weren't big enough.

aha! I see the problem.

those hoses are filled with green liquid.

silly man. those are *internet tubes*. even sillier is that he used the wrong liquid for audio. that's digital liquid inside, I believe.

(lol)

who was the builder, btw? did the article ever mention?

[DorkVader]

The article did mention.

On page two it says it was built by "psychaudio" right under the DACT CT2 image.
