I am just getting into 2-channel listening and am agonizing whether to go new vs.vintage. A pair of Kef 107's are available in my neighborhood. I am not at all handy and naturally concerned about condition, how much restoration would be needed, etc. A Kef dealer would give me a very nice discount on the R700's which have reviewed so highly. What do you think? How would you compare the two? If it helps, I am deaf in one ear and tend to listen to my music at a fairly high volume. Thanks in advance.
The KEF 107 is a fine speaker, but there are installation issues you need to be aware of. You won't need a sub with this speaker, it is truly full range, it gets to 20 Hz with no sweat.
However, the speaker uses a coupled cavity bass system, that requires and an active equalizer, known as the KEF Kube. This has to be connected in the tape monitor loop, or between a preamp and power amp. Modern equipment does not have a tape monitor loop, so unless you plan on using a vintage receiver, which I don't recommend for those speakers, the you need separates. You can not use those speakers with a modern AV receiver. Use of the Kube active equalizer is mandatory for those speakers. You need to make sure that item is included and working, or the speakers are useless.
Like most coupled cavity designs they are not sensitive or efficient, and KEF recommend a power amp in the 300 watt per channel class.
If you have the funds and ability to set those speakers up properly, you will not go wrong.
Those speakers were made when KEF were at the top of their game and not owned by and outfit from Hong Kong.
The only other caveat, is that the drivers use Bextrene cones. Sometimes this material can crack with age. Bextrene is no longer made in the world, and the drive units can not be repaired if a cone cracks.
