Well I wouldnt consider them as pretty, there a lot more prettier speakers around IMHO, but just matter of taste I belive. As for sonic its very good speakers- I found all virtues of focal school and basicaly none of flaws. They sound a bit muddy before burn-in (when i get back after few month speaker sit at the same position, same gear- but sounded much more trasparent)- unlike right pout the box Diablo -which sounds edgy on bigger clasical works and Scala, which sounds sibilant at vocals.
Ok I can describe my impressions if you want. I didnt lived with speaker, just had some listening and tuning sessions (aprox 40hours total)
I always missed bass from Utopia II- Diva, Alto Be, (and when first heard Scala)- same feeling- tight , and natural bass but no real palpable punch. some other speakers are opozite -have very punchy bass but its always same "one note" sound- sounds good on electronic but large orchestras just lack feeling of power and majesty(if no bass) or have unnatural "pumping air" efect (if one note sound) when bass notes a coloured, slow and blur(thought it sound simpressive on moovie track for example) Maestro bass is good for both - its have enought weight and authority on bass but have that fast , and also not boring one note bass.
I alaways noticed how critical Focals are for vocals records, for ex. intolerance to sibilance. they just did not like bad vocal records( be it it pop vocal like diana krall or opera) and spilling that junk to ears. Sonus fabers for example even if have excessive high frequencies in general(at least models i have listen) but its just listenable with same records , I have one female voice test track called "summer samba" its an audiophile record enginiered very "hot" tendency to sound bright and dry. and its not the only record unfortunately in the recording industry. speakers which plays good clasical (strings) never produce good sound on this record its just to much exited, with lot of sibilance. and vice verca- speakers which produce natural sound with that track lack definition and higher halftones/upper tones to strings. I noticed that with Scala- good on small clasical works, but need lot of atention(both gear and listening room) to not sound sibilant on vocals. to my surpsise Maestro did both- voice was chesty weighty as it sounds in real, there still was some brigtheness but it was already tolerable. and sound was quite natural (considering recording material) I heard that record for many time on variuos speakers and understand that neutral speaker reproducing this record with just small hint of brigtness( I there were peak consult speaker with sounded almost perfect on this, but i didnt liked them on ordinary quality records) overal coherence of Maestro is top- never hear big 3 or 4 way speaker which sound like single point source. even from the 2 meters speaker sound slike single driver.
and sound is which i consider balanced- its more laidback "and not in your face" than most focals and especialy wilson puppies which "bark" at some records - closer to sonus faber camp , but it doesnt lack palpability and imediacy. neither with vocals or clasical music it discracted from music- nothing screams, nothing stood out and nothing missed. and I have hard time to analyzing it, my ears wanted just listen to that record. its rare case as I always listening a "quality" on Diablo rather than record itself (that was reason why I leaved them from my bedroom system)
there is a dificulties as well with Maestro, at least I encountered it-
1)positioning- they sound basicaly well focuced from the first moments, but i have real problem to get balanced upper bass(on some records speakers sounded "boxy" and "too big" ) and lacked 3D. i started to moove them around and at some point took from back wall more than 5feet, but lastly ended unusualy close to back wall( I expected too much midbass but it wasnt) and only 2.3m between speakers. boxiness is gone then and after toing out and spiking them speakers "disapeared" but it tooked much more time than i expected to get 3d layered soundstage. I even brought my Diablos which behaviuor I know - I shouldnt done that- it was strange- after Maestro Diablo sounded like tiny matchbox- and scream at most record which Maestro "eated" smoothly.
on the next audiotion I noticed that owner remooved part of absorbitve panels he was used with previuos speakers - we both agree taht 3D improoved further to point where I already enjoying listening session on low lights very much.I quess they should work good in plain undamped and reflective room. so my own impressions so far , hope this helps. if anybody have theese speakers could they advice better amp than brystons(excluding class a solid state), VTL maybe?
