I did at the dealer when I placed the order to upgrade, and there is a significant difference. The Kleos offers everything the Delos does but to greater degree. More information, detail, sound feild, musicality. And less surface noise, the Kleos is much quieter. After having both in my home on my table, I feel the Kleos is in a class of it's own. However let me add that the Delos is a wonderful cartridge and in my opinion is way under priced for its performance level. I replaced a Linn Troika and the Delos brought the music out into the room with a intricate clearity I had not extracted from my vinyl in the past. I did have the Delos on my table for about 60days as I ordered the Kleos about 30 days in and it took 30 days to arrive. Either cart is superior in their price range to (in my opinion)all comers.
