thanks syntax for your info . do you still presently use a kuzma airline tonearm ? ( i did not see it listed in your present system but it was listed under " cheers " ) . would you spend the extra money for a tw acustic raven ac1 for use with the airline or would you simply enjoy the kuzma reference with the airline ? is the tw acustic raven ac1 similar to your beautiful micro seiki rx-5000 in terms of performance ? i had heard that the micro seiki machines were no longer available . is the kuzma airline tonearm a pain to live with compared to using a high end standard tracking arm like your graham 12 phantom II ? i have always wanted a linear tracking tonearm ( and the kuzma is obviously a great one ) but i wonder if they are just way to much trouble because of the air compressors involved . thank you for your input . your audio system is amazing . i will be building my system around the martin logan clx ( els with black aluminum frame ) and two martin logan depth i subs . small potatoes compared to your setup but very huge for me . amp and preamp are atmas -phere . thanks for your help . i am thinking that the raven ac1 ( single motor ) plus the kuzma airline plus ( your suggestion ) the zyx universe would be a match made in heaven . and this analogue combo can probably be assembled new for around 25,000 usd if i talk to the right people .
