D200 Mod 2.0.1

[ogs]

Hi ogs,
yes  ground is common for both channels. It was the same for every amp I opened in the past and the D doesn't differ.

The layout of the Pro's is the same for the speaker terminals as I can see. You can have a look at Antoine's System post.There's a picture of his 250 Pro opened. I did not have opened a Pro myself yet and I would meassure first before soldering.

The new mod is still burning in (about 48h now) but very promising as I can hear this big of an improvement just yet.

Can I ask what the 2x10 pin connector is used for? I assume the D-board is using this, but do you know what signals it carries?

As the internal construction is using many 'pin' connections, is this the reason why we see so many different burn in descriptions? If the metal quality or contact area (quality) varies from unit to unit this could affect burn in and sound. Do you think a contact enhancer fluid of some kind would work here?
