Actually higher-end amps may not have protection, particularly ones that follow the minimalist design paradigm and they assume the users will not do bad things.

The reason why SE sounds dimmer is because SE outputs on a balanced amp will have HALF the gain. I strongly recommend you not drive your amp the way you are, even if it has protection circuitry it is not good. You spent how much on the amp, yet will not spend the small bit more to mod your phones? If the phones have 2 cables to a Y then it really should be no more than buying 2 XLR connectors and spending 5 minutes to solder them on. You can then use an adapter to convert your XLR terminated headphones to TRS termination for use with non-balanced amps.

While I do agree with you, how many pages of this thread has gone on with WindowsX flat out ignoring everyone of the logical statements we have politely given. I suspect most of that is do to a language barrier and for that I give him some slack. I think most people in this thread have been very nice to him.

I checked some more about being real balanced amp or not. Mine isn't real balanced meaning its source before sending to output is still unbalanced. That way it'll be safe for amp and headphone since at worst, only balanced opamp should fry if you make wrong connectors.

I apologize for not carefully checking the condition with pure balanced amplifier.

A question to dig a bit deeper. What is the output of your amplifier? If it is 2 3pin XLR plugs then you still have a balanced amp regardless of the source. And you still should not connect the headphones the way you are.

What amp do you have and we can tell you. I really want to assist you so that you do not damage your gear.

The knowledge of these Head-Fiers is impressive. Good readings.

Some amps (like GSX) dont output a balanced signal if you don't feed it a balanced signal. In that case the wires that carry the inverted signal are actually unused. Then there is no problem combining these wires.
Most amps actively create the inverted signal though (like the Rudistor amps). In that case you REALLY don't want to combine these wires.....

There're 2 kinds of balanced

1. unbal -> bal conversion
2. pure bal

My amp "grace m902" falls for the first category because it uses unbal as input source before proceeding balanced output conversion.

Is this your amp? m902 reference headphone amplifier

If so I am not sure it has balanced outputs, it has balanced inputs but I do not see and balanced outputs. Unless they are using 2 mono phono plugs for balanced outputs.

Now if it was an amp that takes an unbalanced input and converts it to a balanced output then you do NOT want to tie the negative signals together, this is very bad.

The grace M902 does not have balanced headphone output.

So 6 pages and the OP does not have a balanced amp. Maybe we should have asked what amp he had from the beginning

This is just hilarious. I've read all of these 6 pages. What an end.

the grace m902b DOES have balanced outputs, via the rear. the two "speaker outs" are actually TRS jacks, one per channel, balanced.

not sure how WindowsX has his headphones connected, and how he's using headphone through those outputs - im dying for him to post again

grace m902 has balanced upgrade with TRS jack like most studio equipments have. It's not balanced headphone output as you guys know but its output can drive full-size cans from specifications. Haven't you guys ever tried plugging headphone in PC's speaker out jack? They both work well and this is one of those regards.
