    i did not suggest going to the 225 watt option because of the power but to get away from the type of bi-amping being used.

    It's 225W bridged, so the bump in output does not occur by default when foregoing the bi-wiring option. I completely defer to the OP's right to self-determination. But what confuses me is why suddenly it is so taboo to allude to a wattage deficiency when time and again on this forum so many LSiM owners have said at least 200wpc is needed for this series to sound its best.

    The LsiM line simply has a boosted treble compared to the Lsi line.

    You either like that sound or like the flatter Lsi sound.

    I've had the 703's and a friend had the LSi9's years earlier. The LSi are more laid back and easy to listen to speaker.

    LSi9 Measurements



    The goals Polk had for the LSiM ring radiator tweeter over the LSi was to improve the top end response, dispersion, and eliminated horn loading. The LSiM line is more revealing and the 703's have a 5dB rise on the top end. The sound and interaction with the room may create a totally different experience...good or bad.

    Myself, I never found the tweeters harsh or distorted sounding. However, in some rooms maybe room treatments might be needed? or possibly a little 2-3dB padding on the tweeters like the switch that some vintage speakers have. Or maybe even a little EQ on the top end. Your TX-8050 receiver has treble control centered at 20KHz. Have you tried to reduce the level some?
    EXACTLY!!!
    Occam's Razor.....

    The most obvious answer is usually the reason.
    Nothing to do with power or cables.

    One speaker clearly has about 3.5-4 db more treble, so it will sound LIKE it has more treble.
    It is up to the listener if they prefer that sound.

    While one speaker has more treble, it only becomes more exaggerated by the associated gear and source material being used.

    A more revealing speaker will reveal your other shortcomings, possibly not as audible on a lessor speaker. So you have 2 choices here.

    1- Start upgrading the other areas of your system. Doesn't have to be done all at once but you will notice better sound after every incremental change in things already suggested.

    2- go back to a lessor revealing speaker and keep everything as is, if you like that sound you had, then you've lost nothing and invested nothing.

    Good points!
    Hearing acuity factors in also. Between my husband and I, we notice I prefer a bit less treble than he does over the last several years.
    years back we had the exact same preference, and I would imagine over time, what is too much to one person would become just right perhaps.
    Lots of variables for sure.

    It does not offer a ton of power, but that is not your problem. The clinical and sterile power and preamp and lack of a good DAC (and of course, starting with MP3s) are the problems. This would fix everything but the source in one component...

    I was going to post this, but decided to mind my own business ;)

    I enjoyed by 703 with the Peachtree. Sound was very good and I personally love the looks of the Nova. Even though I've moved on to better integrates, this is a piece that I sometimes wish I still had.

    Um, I was interrupted. Thanks for calling me out. You could just ignore my post
    @clipdat as it wasn't directed towards you. Wait a sec, ignore...

    The point is the OP might have to play with them to trying different things
    upstream to get them to where he/she is happy. (As mentioned)
    I wouldn't just give up on them.

    OTOH, if you don't like them you don't like them...

    Why are you even using any Polk products? I thought you swore off anything to do with Polk Audio due to this forum which you detest, but yet for some reason still visit daily.

    I appreciate all of the feedback here. If anyone has other ideas or has had a similar issue I'd love to hear them. In the meantime I am going to play around with some of the suggestions here and see if I can notice any differences.
    Tons of responses here but no report on what you've tried.

    1) Use the best source that you have, so pull out that CD player.
    2) Rule out a problem with a tweeter or crossover. Play music that causes the brightness, distortion, etc. and see if it is on one side or both. Switch the speakers if you have to or play one speaker at a time, etc. Also, listen to high frequency test tones and pan left right with the balance control.
    3) Are the speakers toed in? If so, you might prefer a less toed in high end response.
    4) Does a little treble adjustment help?

    I think the above is a good starting point. Report back what you find.

    More resolving speakers require better equipment and source music upstream.

    Yes, I know. Will be trying a lot of this stuff when I have time, possibly this weekend. I appreciate the number and variety of responses. I wanted to have a good idea of a bunch of things to try before I made any changes.

    This is an interesting option. If I were to make some changes in my gear, I would really like to retain some optical digital inputs if possible, because I also run my TV audio through the speakers, and the connection is optical digital. And the price isn't too bad. Could probably sell my existing gear and add a little money on top and get one.

    Think of highly resolving equipment like its a microscope on your system. Remember the last time you watched standard def TV on a HDTV? Awful, right? Grainy, fuzzy. Same with audio. The better your equipment is, the better it has to be.

    Gotcha. That seems to be the general consensus here. Still going to play around with my existing equipment, but most seem to think that some upgrades in equipment and music source would work wonders.

    Update: So I played around with some different sources and higher quality files (FLAC and CD) on my old equipment, changed up the way I had wired the speakers to using a single wire for each, and couldn't get away from the treble problems I described in my original post. I really appreciate the suggestions and feedback I received here, there were a lot of good things for me to try.

    I bit the bullet and made a big upgrade to a Parasound Halo Integrated (used from ebay), and WOW, now I see what I've been missing! The problems I was having with the harsh treble/distorted treble are totally gone, and everything sounds amazing! The difference the new integrated amplifier made is pretty incredible. I know it is a huge step up in terms of quality, but I was still amazed.

    The other thing that I'm really happy about is the sound of vinyl on the new amplifier. Through the Onkyo, records almost always sounded really flat, boring, muddy and kind of muted(?) maybe... best way I can describe it. I always preferred digital because my vinyl always sounded like crap through the Onkyo, which was very disappointing, because I do enjoy collecting and listening to vinyl. Must have been a pretty bad phono stage, in addition to the amplifier just being not as good in general. Now the vinyl sounds much clearer, more detailed, and dynamic.

    Thanks again for all of the input here! Looking forward to remaining on this forum and learning more, seeing everyone's systems, and sharing my own future upgrades.

    @CottageChz Have to ask, but what age range are you?

    Obviously someone younger will have better high frequency acuity, and that combined with the Lsim being voiced with more treble than the Lsi series, could simply be a bit too hot sounding for you.

    So the guy solves his problems by taking the advice of experienced members and is now completely happy with his choices, and you come up with this?

    @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!

    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.
