Great review Gene. I would have thought that the noise floor would have been higher with the lack of the isolated card design of the MPS 1.
I know you are not easily impressed, so your preference of this model over the MPS1 says something.
Nice job
The IPS-1 still has independent mono block amps just like the MPS-1 but you can't slide the modules in and out. The MPS-1 would have identical SNR if you pull the limiter circuit off which is easy to do. Emotiva will instruct customers on request if you wish to do so.
I mostly prefer the IPS-1 b/c its more manageable and easier to setup.
