Very nice speakers. Easy to drive. Impressively clean up high and good presence. Very wide sound stage. May be a little bright but not too bad.

Vintage Kef in general has such wonderful mid range performance. I would recommend recapping the crossovers and rewiring with bypassing the acoustic contour control and then adding some nice copper terminals on the back for your speakers to plug into.

Then your well on your way to musical bliss!

re: Model 104

I have both 104 and 104ab models and recommend the 104. It is clearer with more sparkle but there might be something wrong with the 104ab. The ab are just OK and mine sound a bit muddy by comoarison.

I bought my 104s used in 1975 for $250 each I think. If anything they have improved with age and never been serviced. Mine have been run by a Marantz 1060 from 1970s that I bought rebuilt about 15 years ago.

I stream TIDAL HiFi from a Galaxy Tab A (with S-pen) through blue tooth 5.0 to an audioengine b1 receiver. This setup rivals my high end SACD.
