How does or in what way does the headphone opamp make a difference to the main output?

If you've seen 'The Matrix' I suppose you could say it's like taking the red pill, in that you won't be able to go back to how things were before. In other words, you wont be able to stop fiddling now you have started.

Personally I found the removing them opened up the sound a lot, but then I haven't really got the skills to put it back in place to compare, it was a leap of faith and the tight space led to me damaging the cap slightly, so I just removed them altogether.

I think that every member of this forum has seen "The Matrix", although I also think that my grandma have not seen it, but she is not member of this forum, neither she know what the DAC is

Anyway, it is an excellent explanation of what can happen if you remove those caps. Is there more info on this forum about removing those caps?
Cheers (must think of blue or red pill now)

I agree, I even tried to listen to DAC with only one opamp, and the sound is the same.

There should be more information earlier in this thread and in the sticky thread. The majority of people liked the change, although someone did have the caps put back.

I tried changing the headphone opamp for differences on line out but decided it made no difference or was too small a difference to matter, especially as it complicates issues when balancing line out and headphones.

You also have to keep in mind that there are 2 types of listeners here; those with headphones and those with stereos.

In my case, I've never used the headphone section.

Me too, David. All my efforts have been towards improving the fixed line outputs.

[RoboCopper]

Me, as well.
I am concentrating only on fixed output as I only listening speakers as only speakers can create musical space, involvement as it was recorded. I do not even own headphones, I know you can hear more with headphones and can be enjoyable, but...... room is room, space is space, ......my opinion.

Greetings
This is my first post. Have enjoyed the reading, but more importantly I am very much enjoyng listen to my 7520 with the mods. I am looking to do the audio cap. mod. Has anyone used the Elna SILMIC II 47uF 16V 85'c Capacitors on the six you replace on the Audio board.
Do the capacitors need to polarity or can they be Non-polarity?
Thank

[Alexxus]

The way I read it it's non-polar caps.
