Need some feedback from the Allen&Heath DB2 users

Hi there!
I am about to buy the A&H DB2. It would fit perfectly to my setup with k2 and other gear. I do a lot of research regarding this mixer, and I have found strange report from db2 user at one forum. He said that when he turns cue/master balance knob maximally towards cue position (when he should hear only cued channel by headphones) he still hears some sound 'bleeding' from master. I wouldn't ask about it, but a&h responded as it is normal with this model. Is that true or I am just freaking out? ;) So now I need feedback from xone users - it happens with your mixer? Or it was just one invalid unit? DB2 will not fit my expectations, if that case would turn out to be true. Thank you in advance for your replies.
Best regards,

I've had my DB2 almost since the release date and have fortunately had none of the issues I have read about on the Xone forum, that is using Audio A10, internal sound card or digital inputs depending on what I'm doing.

I would also say that at first I wished I had gone with a DB4 but once the chained effects were made available on the DB2 I think it offers more.

I also don't get the people criticising the lack of updates on the effects side, if you need more than the fifty or so present out of the box you're overusing them!
