I've had both the Rega Kytes (originals) and the Rega RS1s.
Both were excellent speakers.
Both needed to be close to the front wall but the RS1s were more picky about placement.
Get it right and they have a lovely breathing midbass that can be quite addictive.
Neither are anywhere near to full bandwidth or scale but the snapshot of the recording they present you with can be endearing.
From memory I'd say the Kytes had better tone but the RS1s had better dynamics.
