Mine is the Kleos, I started with a Delos and upgraded right away to the Kleos. The dealer did add a new motor at the time as well as "tune up/tweaking" to my LP12 which I am sure can take some of the credit for the vast improvement is sound reproduction, but I still give the majority of the credit to the Kleos. The other big improvement that was of no cost to me was a replacement via warranty of my LS26 by Audio Research. I had experienced some problems with my previous LS26 and they just replaced it with a new one, and I can't say that the original was bad but the new one is just superior in everyway. So I guess I had 2 items and one was basically free. Thanks to ARC and Jonathan Carr for fine fine products!! May 2012 bring me the funds to buy even more:)
