    It isn't that difficult to configure software volume control with sufficient bit headroom. That said, if you can't do that and most of your listening is at volumes so low that you're near maximum cut, I guess you need to look at gain structure...heh.

    As far as dacs go, until one has the means to experiment properly, gauging the impact of topologies is also difficult. A commercial dac may have the latest buzzword in tech, but have compromises in other areas along the chain. Makes it difficult for the layman (technically, if you can't swap component parts of the dac out to gauge their impact in a given circuit, you are a layman) to judge what is good and what makes a real difference.

    Totally agree with you. I think the best prefab box on the market for the price now is by Pro-ject. Either their digital pre or the DAC DS2. If the parts quality in the DAC DS2 are even close to the pre digital, it's the bargain of the year.

    I'm pretty satisfied with my O2+ODAC. Generally well regarded and well received by the audiophiles, although the designer (NwAvGuy) generated a lot of impassioned love-or-hate controversy in the audiophile communities (especially with his What We Hear and Op Amps: Myths & Facts articles). This is not quite a "perfect" device, it does have minor flaws, but it is excellent and (to my ears) was the best of many that I've personally tried out (as of mid-2015, anyhow, there might be newer/better devices now).

    Absolutely. I had the O2 headphone amp, great little box. The controversy over the designer is certainly interesting, though I've placed it behind me at this point, in respect for the simplicity of his designs, and his integrity to challenge the status quo. That DAC is sure to rock!

    Talking just for info

    for info the ROG STRIX Z390-E GAMING Have CODEC S1220A and in their website its very clearly stating to handle : "With two op-amps on-board you're able to pump exceptional audio to your favorite cans, with 32-600Ω-headphone impedance for great flexibility."


    so if anyone have an audiophile headphone he should be able to drive the full volume without an issue. regarding the noise or interference ofc the dedicated out of the case Sound card is going to be better.

    if anyone have an asus motherboard who can confirm running a headphone with 250ohm or above would be nice <3

    I've used Beyer DT880/600s and Senn HD58xx/300's without a problem, and that's compared to an Oppo HA-1, and Topping A30.

    Are you having problems with it? Lack of authority, or volume?
