I think the balanced connected to a good deldicated amp will be fabulous.

What about clarity and treble

If it's true then this should be plenty, provided there is no clipping

6xx need good voltage swing. All the portables run at 5v batteries so max voltage swing is well under 5v. That's why I think 6xx sounds best with desktop amps. But then again at moderate volumes I guess it drives well.

Yes ,thanks. That seems a steep roll of , rolling off at 150hz. Sub bass will really be affected.

So will it have any affect in the sound quality.

Are you sure capacitors are added in the output stage to offset dc voltage and not to regulate power supply? Because why would zishan do it , capacitor in signal path =bad.

There is still little bit channel imbalance with my unit on firmware 1.3

Is fiio A5 better than topping nx3s?

Will the opa 1612 produce ocillation

Is it possible to use opa 1612 or opa 1622.

Can OPA 1612 be used instead of ne5532. I think it's newer so I presume it's better.

Please include ldac and aptx hd.

Best portable one would be chord mojo. But then again it has battery issues and basically no warranty.

Ok in that case I retract my conclusion about op impedence. But what I said about btr3 is real though. Maybe the device has good low end after all. Google gave me wrong value .
