Ok ,
Both arguments hold water and as MikeL had previously suggested its as much system execution as any and Yes there are inherent advantages /Disadvantages in all speaker topologies but mostly it comes down to what the listener is sensititive to and while i have my preference topology wise , Im pretty careful with how i play that audio panacea Curve ball...
Aside ,
I prefer (like MikeL) a large 4 tower system , where the Bass units are seperate from the mains for best localization and positioning , yet , I also agree with Sharky Mike about Dome tweeters vs Horns and instead prefer Linesource instead of point source, yet and this is where that audio curve ball gets you , MikeL has proven in his room and his meticulous setup, NF point-source can work at SOTA level too ..
Horns,
I'm sensitive to Horn shout for dynamics , i do find Linesources can exhale without the shout , so they are much better here , yet i have never heard any other speaker topology capture the purity of tone on Brass, Violins, Cellos and double bass like a large fullrange Horn...
Less also not forget High sensitivity Horns have a big advantage , SET amplification ...!!!!
Less also not overlook MikeL is a very experienced and meticulous Audiophile , if there was ever a way , his journey , approach and effort was always it IMO, impressive at every junction , is he the only one doing so , No, i mention this because his overall system performance may not be typical of the genre .
SET amplification and big horns can be very special thou , so is sitting back , sipping wine and Speaker King hunting ...
