Used ATOC9/ART9 and heard the 1000.I wouldn't hesitate getting the ART1000. That would be AFTER putting a nicer arm on the proven Technics foundation. Your ART9 would have been in a different league with a Kuzma or whatever.
Have you considered the ART9XA?(Low output) More refined presentation compared the the .5mv . 1000 still has all the AT traits, but yet another level of refinement expected for a "super cart"
Any of the upper level Soundsmith carts should be included inyour final lineup. The Susurro is in the same price point as ART1000. Rebuild is the plus over the rest.
I've repeatedly(like a broken record) mentioned hearing the lineup and keep a $400 entry level Otello as a backup. I hear a midrange presentation unlike others. My reason for suggesting SS.
Presently using Kiseki Blue.
