    @K_M I am early 30s. I still find that the speakers can sound kind of bright to me, but i don't have a ton of experience with other high end audio equipment to compare the sound of my system to. And it's not a terrible thing, it doesn't bother me, just an observation. What I was finding before was that the treble was overly harsh to the point that it sounded distorted to me, and that is certainly not the case anymore. I know what you are saying about high frequency acuity... it's obvious when I can hear some high or low pitched noise that drives me nuts and my parents are like, "what are you talking about?"

    @nooshinjohn It's ok man! I am still really happy with my choices, and the great feedback I got here!

    I’m in my mid thirties and probably have some of the worst ears on the forum. Having bad ears doesn’t detract from knowing good sound, or bad, when you hear it.

    I do recall there being isolated issues with the LSiM tweeters a while back where they would distort especially on certain piano notes. Have all those issues been resolved?

    Not worried @Cottagechz... and welcome aboard. My comments to K_M will be understood better as you hang out on the forum. They have a habit of posting things which are not helpful and contrary to the extensive knowledge and experience of many here. They just cannot help themselves.

    Glad you were able to find the solution to your problem and that you expand d your experience by picking up the Parasound. You have the makings of a sweet setup.

    Cool to hear. My husband and I have different hearing acuity possible due to our age difference.
    He hears the LsiM series as just about right, I hear them as having boosted treble.
    With the lsi line I hear them as just right, he hears them as a bit dull sounding.

    So your hearing seems more in line with how mine, or at least more similar.

    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.

    The tweets are only related by the fact they call them tweeters. Their similar appearance does not mean they are anything more than distant cousins.
