KEF Reference 1 v 107/2

I replaced KEF Reference 107/2s with Reference 1s because I was concerned about inserting the active unbalanced KUBE between an Ayre KX-5 Twenty preamp and VX-5 Twenty amp.  I had had a bad experience adding an active balanced Bryston high-pass filter between the preamp and amp, and was warned by Charles Hanson to avoid inserting active circuits between the two.  I regret I never tried the 107/2s with the Ayre gear.  A balanced passive Marchand high-pass filter does no harm.

The point of my previous post was I never compared the Reference 1s with the 107/2s.  Anybody made that comparison?  Anybody with experience in inserting a KEF KUBE between an Ayre preamp and amp?

stevet59, I augment the KEF Reference 1s below 80 Hz by a pair of Velodyne HGS-15s with SMS-1 acoustic room correction, I’m unaware of the subs except when they do something I know the KEFs can’t do, e.g. vibration from a low pipe organ pedal note.

As noted above, the KEFs are high-passed at 80 Hz by a passive balanced Marchand filter.

My one complaint about the Reference 1s was that large orchestrations didn’t scale as I remembered with the 107/2s, but the addition of the subs cured that. The setup can sound very large when called for, yet remain delicate for the small jazz and baroque groups I prefer.
