I hope all be good, because beyerdynamic DT 770 PRO is not easy to drive too (250 Ohm) - but I have no problems with them on TOPPING DX3PRO.Thanks for the answer ... so maybe I would like to buy another headset..

One thing that speaks for Topping is how much service I got. My original dx3 pro managed to burn a few of my cheaper test headphones ... to much power, they got hot and died. According to Topping, to whom I sent my unit back, a damaged Opamp. After that, topping immediatly sent me a new unit, which so far, I have not dared using, as I only have expensive IEMs remaining. To that comment, Topping even offered me to send me a new future updated version ("V2"?) that will come with headphone protection ... not exactly sure what this is, but it sounds like a good thing to me. So service-wise I got some of the best service I ever got from any company by Topping.
Did they happen to mention when they’re expecting this V2? I’m not touching this until that headphone protection is in it. I can’t believe you are this satisfied after losing headphones to this.
There are things that are "illegal" on headphone out. One is DC output which occurs when the output stage shorts out and just feeds the power supply to the headphone jack. This will kill the headphone for sure. So a DC detection circuit is used to immediately shut off the output when this occurs.As for headphone protection: Can someone explain to me, what this is? Does it just limit the current going out? How does it know how much a headphone needs and where it has to stop it? I'm no electrical person at all..... mayber Amir knows

Are you sure it is AAA?Received my unit 5 days ago, batch 1904. Replaced my fx-audio dac-x6, very impressed with the quality and sound, amp drives my dt880 250 Ohms no issues at all, volume knob very precise and linear like digital on windows. BT works perfect, remote also with 2AAA betteries which is good. Nice display and overall solid build.
I really hate to do this and I have been a staunch cheerleader for so long.
But I just encounter the same standby issue as everybody else.
Will still look for an exchange.
Oh well, it was excellent while it lasted.

Please reach out to me @TP-Wong . Or maybe somebody can tell me how to get to topping sales support.
I bought it via Massdrop around the mid Feb cycle.

The other is thermal shutdown. If a short occurs for whatever reason, the driving circuits can get too hot. A protection circuit can detect the over temperature and shut down.
More advanced protection can detect extreme clipping (overdrive) and again, shut down the output when this occurs. This is the case you are thinking of with too much current being drawn. It would only happen when the sound is hugely distorted anyway so best let it shot down than risk damage to either the headphone amp or the headphone.
may I ask which headphones you use?View attachment 26421black DX3 Pro is very elegant but it wouldn't be a nice combo
AKG 702 64 Ohm, FiiO F9 + bluetooth Cable TRN with Apt X, FiiO FH5, BGVP DMG all 16 Ohmmay I ask which headphones you use?
Yes.Is it possible to dispose of the headphone amplifier with a shorted / cut / broken IEM cable?
