These DC offsets are alright, they are within all specs.

posts 1548 and 1549 seem to be totally unrelated.
What are you asking?

No, no mods yet. I read something about hot-rodding but am not totally sure what entails (enough info as it is to process in the two threads). What mods would you recommend?

With just a couple of hours of listening done, this is an exquisite upgrade to the standard B1. Congrats to the designers.

I would enjoy the sound for a while before considering the tweaks.

wushuliu, do what tea-bag sais. Let the circuit burn in properly, get used to its sound and enjoy it. After some hundred hours, perform the mods so it will be easier for you to notice some changes.
Just for scientifical purposes

No, I have no intention of modding with this board anytime soon, if anything I have another hypno and 2 mez boards that I can work on (prob the mez as I have multiple inputs).

No doubt, the performance of this design is euphoric. It's like going from really great well-produced cd to SACD version of that cd. Overall characteristics are similar to standard B1, but articulation and resolution bar is raised.

'Money' from DSOTM just gave me goosebumps...
