I’ve owned some of the mega speakers in my days - Meadowlark Ibis, Silverline Monte Christo, Montana WAS, Ascendo top of the line, Dali MegaLine, Vivid Audio GK1 and now Perfect8 Force with 4 sub stacks.
All of them ended up beeing modified in some way or another. All of them ended up with directly coupled woofers and active base x-overs/biamped.
Each of them had some strengths and weaknesses.
Based on my memory Medowlark Ibis for a long time was best in under 100K price range providing great balance of transparency/bass slam/ and naturalness with slightly warm and romantic tonal balance, and Dali Megalines with their ability to resolve micro-dynamics, and through incredible soundstage, openness and combination of micro and macro details after some serious modes are making great sound in our bedroom to this day - they are somewhat limited on the bottom and need to be agumented with subs - not an easy task as you need ultra-fast subs though. Montana were retired to HT were they truly belong - most dynamic loudspeaker of them all with good natural timbre. Silverline Monte Christos were very musical with warm midrange yet open highs and decent bass and Ascendos were extremely coherent throwing a best lateral soundstage I’ve heard and sounding great at the low volumes, they also had great bass integration but were anemic and did not dig down deep enough.
Vivid Audio GK1 ended up being my overall favorite speaker amalgaming most of the good feature of rest of the speakers reaching best compromise - preforming almost everything as good as best of the best. Lateral imaging almost as good as Ascendos, dynamics and bass close to Montana’s, coherency closed to Ibis, depth and details almost as good as Dali. In almost any area they were number one or close number two of the pack. Some of the areas were Vivids were lacking was micro dynamics, low-volume playback and sense of true air(as compared to either true ribbons of Dalli or Audax Golden Eye of Ibis). We do need to be mindful what this is not a true shortcomings as they are noticeable only when compared to mega speakers who’s specialty lies in those virtues.
Now let’s enter the Perfect8 Force. I was lucky to get only pair of Force in US (one of 4 worldwhide). These things are crazy. They do everything better than any of above mentioned speakers and by a wide margin. They dynamically outdo not just my mighty Montanas but any speaker I’ve ever heard including Clement Perry’s Sunny Kings and Avantgarde Trios. Their transparency and staging also outdo ANYTHING I’v heard by far. Midbass region - impact, presence and detail is impeccable and tweeters – hah – what tweeters. Adding 2nd pair of subs, replacing power amps on the subs to Symphonic Line Custom and having Rick from EVS to modify bass x-over – this things are heavenly now in the bass region. I’ve never heard any system provide true imaging of the drum set – exact position, depth, size and shape of the drums until day I’ve added 2nd pair of subs.
As far as midrange goes – well – prepare to be shocked. Perfect 8 in my system was able to execute what no over speakers I had even remotely attempted to try. It took PHY based single driver speaker driven by world class custom 300B SET and clearly outperformed it on both male and female voices.
I’ve yet to hear any other speaker capable of doing any aspect of sound reproduction as good as Perfect 8s
And it does all of the thing equally good with an exception of midrange – it does humane voice to the point were it passed my dog test – My voice reproduced through it was able to trick my dog in doing commands then I was standing between speakers .
