I am using Audioengine D1 with HE400i right now, but I just ordered a HD650. So do you guys think I need to buy an amp like O2 to enjoy HD650? Or Audioengine D1 is enough for it?

meikaoThe Audioengine D1 will probably be enough from what I'm seeing of it's specs. You won't be able to turn them into speakers like a more powerful amp, but it should be plenty for normal listening levels with a little bit of headroom. I'd give it a test before buying something new.

Zilfallion12mw @300 ohms The D1 is a piece of junk, HD650s want 300mw @300 ohms, and it's nothing to to with loudness, they're completely underpowered on the D1 and so are the 400i's.

Uzuzu12mw@300ohms is enough for 110dpspl. I'll admit that amping is not entirely about loudness and there are other factors involved, but 300mw is REALLY pushing belief.

ZilfallionI got HD650 this morning, and I think you were right. D1 was able to power up the headphones very very loud, and it already sounds better than 400i in my opinion. However, I am not sure how an extra amp can improve my HD650 at this point.
Well I already ordered Magni2, so I will report it later. Thanks!

UzuzuI tried with D1, and I feel D1 is very powerful enough to run HD650. If you are only talking about loudness, I think D1 is enough.
However, I already ordered Magni 2 so let's see how the extra 70 bucks can improve my HD650 at this point. Thank you!

meikaoI'm not talking just about loudness. The hd650 will sound less "full" if you are underamping it, in which case you are. The magni 3 will fully drive it, update us when you tell the difference, it should be very obvious between the two. Still, the hd650 sounds kind of boring out of SS but that's just my opinion.

UzuzuDo you think there are a big difference between Magni 2 (non uber: $65 from online marketplace) and Magni 3 ($112) ? Is it worth to pay extra $47 to upgrade from 2 to 3?
P.S. I sold my Audioengine D1, and now I only own Dragonfly Black (they sounded very similar, but dragonfly has stronger bass and slightly weaker treble). I am planning to lineout it to Magni 2.

meikaohuge difference? No. Both amps are clean, both are ver powerful. The magni 3 though has a noticeably larger amount of power output, I would say it would run the hd650 better. As for any other headphone, either amp is literally going to sound just as good for you.

I got Schiit Magni 2 today. Use Dragonfly Black as a source, I realized HD650 sounds more clear and all the sounds are more distinguished (?). Very hard to explain this, but I think with magni 2 I can hear much crisp and enjoyable sounds from my headphones.
It was very worth the money ($65), so I surely recommend people to get Magni level amp (like O2? Fiio E09K and K5 might not bad too if you can get it around $50). Thank you Uzuzu for reply and help!

The audio on my pc38x is not working

One day I just plugged in my Pc38x and they stopped working. I tested the mic and it works, I've tried changing the cord multiple times and have adjusted the volume disk, none of this has changed my situation. I've tested the headphones on my PC, switch, and PS5 and the audio doesn't work there either.

Hifiman x Dekoni Cobalt or Massdrop x Meze 99 Noir

Im looking to buy a set of closed back headphones under $200. So far the two main contenders are the Cobalt and Noir. Has anyone compared these two? which seems to be better? Both are around the same price. Ive heard the cobalt is lacking in bass, while thats not ideal im not too worried as I dont often listen to bassy music.

Xduoo Poke II repair

Hi friends, I recently had a mishap with my Xduoo Poke II, that is, it fell out of my hands and now it turns on but the command buttons now work sometimes and sometimes not. I have written several times to Xduoo directly because it was with them that I bought this Dac and to find out what I can do about it but after two months I have not received a response. I live in Mexico City but I would like to know if anyone knows of a technical service in the US that could repair my Poke II and know if it would be worth it for me taking into account the cost of repair and the issue of shipping, or if it is better to think about buying a new portable Dac. Thanks and Cheers everybody.

Refusal to take responsibility.

Hi, Just thought I would make a note here of your handling of my issues. I ordered a pair of HD6xx headphones and then earlier today recieved the package. I drive to go and get it, as I like in the UK I had to pay import tax and handling fees. These total £47.92. The breakdown being £35.92 in tax and £12 in fees. These taxes were calculated of the shipping label of the box, which marked the shipment as the 6xx headphones of $199 value. Before leaving the parcel depot, I open the box to find a $35 lord of the rings mousepad. So now the problem is not only do I not have the headphones, but you have marked the shipment wrong so I have paid £47.92 fees for the handling of the mousepad. Which would have acrued £0 of fees if marked correctly as it is under £135. I go back to the desk but as I have already paid the fees I am unable to reject the shipment, but as the box said 6xx, there was no way for me to know before opening it. I contact support and they offer me a replacement, which...
