I have owned and used the Kronos Pro and in my opinion its the most "overrated and hyped" turntable i have owned used or heard anywhere....
I have heard the Techdas AF0 on show i have visited this room 10 times and even in show conditions it was to me clear the most natural holographic fast dynamic and magical sounding TT ever its a masterwork its the Stradivari violin of the TT s its very expensive but its deserves if you can pay.
I have never heard the AS2000 but when i take look the the design and topology i could buy whit out hearing it once it looks very promising design and i am pretty sure the sound will spectacular.
Probably the Rockport Tables and the Goldmund tables are also in the premier league i have never heard those but i can believe....
I am using the CS Port LFT1 TT whit the own linear tracking arm for the last 4 months and based on my experience whit the Kronos Pro the Cs Port LFT1 will eat new "star war design" Kronos as a cookie on side of a cup of coffee
The Cs Port LFT1 has a retail price of 57000 euro including the linear tracking arm (which is a competitor to any other very expensive arm on apart from this on the market) by example its so much better in every area than the Techdas AF1P whit a retail price of 185000 euro (little more than 3x CSPort LFT1 price including the linear tracking arm) and you need a very expensive high class arm for the Techdas AF1P lets say 210000 euro including a upper class arm and still the CS Port LFT1 is a killer its has 95% of all superior qualities of AF0 for 15% of its price!
