I agree with what Ernest said above....
My opinion is that for the front left and right channels I would get the Stratos, for surround channels in HT I would get the LA II's.
I think that MB is making a gift of the LAII's for $400 pair intro price!
It really is difficult to tell the differences between the two amps when they were in different systems in different rooms playing at different volumes.
Having said that, I heard the LAII's through my new custom speakers as well as through wood 4.0's and wood 3.0's.
In no case did they sound veiled in any way. None of these speakers are capable of strong bass however so that it was tough to tell how well they controlled the woofers.
As mentioned above, until there are some side by side comparison's, the Stratos is a no brainer. For the price of the LAII's, getting them for surround channels is also a no brainer.
After some side by side comparisons, it may be that the LA II's could be as good as the Stratos, but I could not tell that under the current listening conditions. For the intro price I don't think you will find a better amp than the LAII.
