I think Albert makes a great point,regarding a "valid/valued" suspension.It amazes me as to how this important parameter is so easily dismissed.No suspension can match a good air bearing design,and the Walker seems to be a great,thoughtful design.Sooner or later,a good suspension becomes necessary.Ever feel or sense a truck or airplane while your "massive" table spun discs?Those looking for an air bladder(active,or passive)to put under their massive table,only complicate things since these are not tuned to the design.Yeah,Basis,Walker,Sota and the host of other well thought out designs.
As to ultimate performance of the host of great tables out there,the actual ultimate performance will still come down to how well it is "tuned" into the set-up.A dealer,or designer can only take us so far.It will ultimately rely on the "hands on" of the hobbyist/owner,and his sense of audible perceptions.Not really easy,with many designs!A nice challange,that can be fun.
That is actually one appeal of "analog" to many.The hands on,tinkering,that allows one to think he/she has a bit more "feel" for the table/arm/cartridge set-up!
BTW,in case I am coming off as some kind of know it all,assuming I have my set-up "right",I have never been totally happy with my own skills.The "best" clearly lies elsewhere!
Best to all!
