The Cal Audio Labs unit has gotten better and better with break-in. I have my cake and am eating it too, love the unit. Great,though not as good as the very best, two channel performance. But certainly, certainly, performance on two channel that is hi-end and better than a lot of strictly two channel pre-amps that I have heard. Out of the box, the soundstage was not as wide as my old Proceed AVP but after about 50 hours of break-in, it has really begin to shine. Seems like many people have not heard the unit and do not know how good it is and think "oh another surround processer claiming to be high-end." This one really is.
