An absolute no-doubter upgrade. When i got the Gaia III’s for my old Egglestonworks Emma speakers, the difference was far more substantial than I’d expected.
I’ve since upgraded to the Egglestonworks Kiva speakers, which unfortunately are so heavy that they required me to replace the Gaia III’s with the more expensive I’s but I did so without hesitation and sure enough, they were a big upgrade as well - though slightly less dramatically than with the Emma’s, possibly because the mass of the speakers made the difference smaller.
