FLA the stacked Quads did somethings very well,but other things not so well.
They were a system that drew you into the music.
I had different amplification then(Atmasphere MP3, S30)so I can't compare .
What I can say is that in the same room where so many speakers have held court, the GV aren't just contenders.
They have more virtues than faults, and they aren't yet broken in.I need another 100 or so hours.
A similarity to the stacked 57, is in coherence,and mid range clarity.
Detail, but not harsh or sharply edged.
No sign of strain,just effortless sound as did the Quads sound on most light jazz and folk, rock.
Vocals are spotlit ,much like I remeber the Quads did.
If anything, the GV ,with some music sounds very similar to a good stat, and I have had plenty of those.
I have never liked multi driver coned systems, when I tried them,I eventually let go of the increased dydnamics, infavour if the wholeness of a good panel speaker.
The GV get very close to that panel sound,and then go a bit further in other areas that count.
I am very pleased,because I know I could not afford the speakers that deliver similar sound.
