"Appreciation of audio is a completely subjective human experience. Measurements can provide a measure of insight, but are no substitute for human judgment. Why are we looking to reduce a subjective experience to objective criteria anyway? The subtleties of music and audio reproduction are for those who appreciate it. Differentiation by numbers is for those who do not".--Nelson Pass

It's a relief to hear that the OP's dilemma was solved. But, if it was a source issue as it appears to have been in this case, then why was he satisfied with his LSi9? Perhaps the answer is that the LSi9 is a less resolving speaker than the LSiM, masking the limitations of the Fosgate amp. But, is the LSiM so much more resolving that it made that much of a difference to the OP's ears? Is it a coincidence that the Parasound amp is delivering significantly more power at 8 ohms? Could that not a be a major factor in the improvement?

I agree that it could be either of these things, power or more resolving speaker. I personally found the LSi9s to have less treble/be less bright in general, so that probably plays into it as well, whether that's just the nature of the speaker, or the speaker being more resolving, or some of both. But I was also never able to try the LSi9s with the Parasound, obviously. Would love to give the speakers a try side by side with my new amp... if only I still had the 9s. Ha.

The lsi and lsim Series both use a very similar tweeter. (Vifa ring radiator)
If anything the LsiM is simply voiced about 3-4 db or so hotter in the treble.

Saying that it's "too hard" to pursue your dreams is no different than admitting to yourself that you are too lazy to achieve them.
