Atacgene,
We don’t sell the Focals, the Kantas are good the Sopras are much better.
As per Kantas vs Personas both are really good, we prefer the more holographic imagey of the Personas and their incredible coherency and more detailed sound.
The Kantas are very good speakers, to our ears they are a bit richer in the midrange, the treble isn’t as intergrated and the bass isn’t as deep.
The Kantas may be a bit easirer to get right, as the Personas are uber clean and can sound a bit too cool unless the gear match is correct.
