Own LS90's, thinking about LSiM 705's

Curious to know if anyone has owned both the LS90 and LSiM 705, and can directly compare/contrast them.

LS90’s have served me well for years (along with a CS400i center), but I am interested in the LSiM 705 and 704C, thinking that they might be an upgrade in sound quality in some areas.

My primary focus is music in 2.1, with dual Outlaw 12” subs, an Outlaw 975 pre/pro, and a Rotel RB-1582 MKII amp. I also sometimes listen in 2.0 with an Emotiva DC-1 DAC/pre directly feeding the Rotel amp.

My only real complaint with the LS90’s is that they can be a bit harsh/forward in the upper midrange and low treble when the volume is pushed. They can have a fatiguing glare with some vocals and electric guitar. But wow, they image so well and have great soundstage width and depth! They can also handle higher SPL levels well, although the harsh glare comes into play.

Some folks describe the LSiM 705’s as pretty neutral, and others describe them as laid back. Never heard any of the LSiM series though.

Think they would be a significant upgrade over the LS90’s, or more of a lateral move with perhaps just a different sound signature?

As a side note, I’ve also considered upgrading the single cap and resistor in the crossover. What a simple crossover in the LS90, BTW. How did they get by with only an inductor (first order slope) in the midwoofer circuits, I wonder?

    The 705’s seem slightly laid back, but in a good way. They’re a pretty well balanced speaker, with nothing over emphasized.

    If your looking for a speaker that does its job, while not really calling attention to itself, the 705’s should work.

    The 705 are a huge upgrade over the Ls90.

    I would also recommend getting a tube preamp in the mix as well.
    The Gear... Carver "Statement" Mono-blocks, TriangleArt Reference SE with Pass Labs Xono Phono Preamp, Walker Precision Motor Drive, ClearAudio Goldfinger Diamond v2 cartridge and Origin Conquerer Mk3c tonearm, Polk Audio "Signature" Reference Series 1.2TL with complete mods, Pass Labs X0.2 three chassis preamp, PS Audio PerfectWave DAC MkII, Pioneer Elite SC-65, Oppo UDP-205 4K Blu-ray player, Sony XBR70x850B 4k, Polk audio AB700/800 "in-wall" surrounds.

    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.

    Sounds like the 705's will be more balanced and refined than the LS90's. I think that would be the type of improvement I'm wanting, as long as the 705's have good dynamics and can handle higher SPL levels well...let's say peaks up to around 100 dB on occasion.

    The single 5.5" MW on the 705 has me a bit concerned at higher SPL. Given that the woofers cross over at a pretty low 100 Hz, the 5.5" MW has to handle a heavy load of mid-bass.

    I believe I can get a pair of 705's and the 704C in the midnight finish for around $1450 total, so tempting.

    I also have a pair of Klipsch RF-7 III in a separate 2-ch system, so I'm also considering moving those down to the 5.1 system, then getting the matching RC-64 III center, which is a huge, expensive beast of a center speaker. The RF-7 III are pretty balanced, maybe a little forward in the upper mids when the volume is pushed, similar to LS90 in that regard. But man, the RF-7 III have serious dynamics and a very "live" sound. Drums and cymbals sound more "real" compared to the LS90. However, I feel the LS90 have more convincing imaging and soundstage - the LS90 do the disappearing act at times.

    On my phone now so hopefully I can add more later, but I would say, get the 705s for sure. You will love them. But the 90’s are very good as well. It is an upgrade, but not a life changing one.

    100 HS is not low and it is also sealed. I consider the upgrade to LSiM to be pretty massive honestly. There are a lot of variables as always though.
