0 audiobomber Posted September 4, 2019 Share Posted September 4, 2019 I am mystified by your complaint of insufficient volume, porto. I normally drive the DT 1990's with my Asgard 2 amp on the "low-gain" setting. My Korg DAC/amp only delivers 85mW per channel @32 ohms, the Plenue D2 spec says 2V output, no impedance specified. These specs are not directly comparable, but clearly the D2 is more powerful by a good margin. Even my Galaxy A5 mobile phone can deliver uncomfortably high volume levels through the DT 1990. The D2 pecs show it should have no trouble driving your headphones, given a normal level input. Are you using any software level controls? Is it possible you are using the wrong setting? A Sony ZX300 is about as powerful as an iPhone SE. The Plenue D2 is at least +6dB more powerful than that, single ended. And the AK380 isn’t noticeably or measurably more powerful. That’s serious power. If you find that you need more power, you might have the Headphone setting off. Engaged, the D2 slams like Mjolnir. https://headfonics.com/2019/06/cowon-plenue-d2-review/ If none of the above, possibly your DAP is defective? The reviews I've read do not mention a lack of transparency or power, and I have never heard anyone describe the DT 1990 as lacking transparency.

I mean will the fact of both equipments have DACs interefere or even damage the dirivers from the headphones??? You cannot to run through two DAC's. From the specs, it appears you cannot bypass the Cowon's internal DAC or headphone amp. A more powerful amp will make the sound louder, but will not necessarily improve the quality of the sound.

Worth investigating, because the Cowon should be capable of powering these headphones to painful levels. There's also this, which Porto did not comment on: If you find that you need more power, you might have the Headphone setting off.
