Those regs look like a text-book implementation of the Walt Jung reg, in other words very good! Better than the TP Placed supplies, as the opamp gets its juice from its own regulated rails, rather than the raw supply.

I was told by Jensen that the offset would give no problems, that it was well within spec. I think in your case just trying the transformers with and without caps will give you your answer.

In my case I wasn't massively impressed with the Jensens directly on the output of the Sabre - a bit soft and bland - so I'm hoping they do better fed with the much lower impedance of the Legato. If not it's back to finding the best op-amp I can.

I got a reply from Kevin (from K&K Audio), he said 6~7mV would "cause you to lose some low bass". I just wrote him another e-mail asking about the severity of the issue. If it seriously hinders performance, I may add caps or go for gapped transformers. Not sure which is the lesser evil Did you hear something similar from Jensen?

Edit: Oh and btw, I finally got my BII+Legato today! "The post office doesn't deliver mail on Sundays", you say. No they don't, but I was determined enough to drive through a typhoon to pick it up.


Cheers,
Alex
