Had all of them. Kenwood, marantz, sansui and pioneer. The one I feel was the best is the pioneer sx 1250. Kenwoods have excellent tuners but the sound is dull.
The build quality on the pioneers really stood out and the looks are just stunning.
They are getting very expensive. Mine is completely original with the double box and all the paperwork. I use it in a vintage 2nd system and enjoy the heck out of it.
Cheers
