Why is this amp so shit if it measures so well? It's the

Because most headphone amps color the sound while this one doesn't. You'll get used to it. Also note that whoever built it might have fucked up somewhere.

That's wrong though.

You don't assess amplifier quality by listening to it.

TY, reading it.

"The noise floor and residual mains hum of the O2 is impressively low. This is where the O2 shines. Some of the other measurements did show some localized bright spots as well. Unfortunately, when examining the graphs in full the shine quickly fades. The high distortion at even moderate power levels is disappointing and the IMD is lacklustre as well. This is also very likely the reason I found the O2 to be unimpressive in actual listening tests."

>It's the worst I've heard so far.

If you'd stop listening to shitty recordings of shitty music to begin with you'd be doing your ears and your hearing a big favor, son.

it's an amplifier, so it's probably just making the shit your already listening to LOUDER

It does measure very well.

That's what it does but who knows what sort of junk gear is the comparison here?

I'm listening to the best really.

It's not shit. It's just a little flat sounding.

A good solid-state amp should be totally transparent, and the O2 comes close. What exactly are you expecting it to sound like?

>>60032195
Transparency is load dependent and doesn't relate to any amplifier topology or design type inherently. O2 can be transparent and I'd put my money on that it is on almost any realistic headphone load.

Flat is what you're really after. If you actually want coloured sound, add the colour dsp at the media player.

If you want the amp to colour sound like beats headphones or the rock setting - bass boost on your hi-fi... you're doing it wrong
