Do old Acoustats compete with new 'stats or dynamics

I listened to a pair of Acoustat X's driven by their Servo Tube Amp, Audio Research SP-3A-1 preamp, Micro Seiki table with totl Signet cart and it was a captivating presentation that started me on the road of High End Audio. Will the newer Acoustat models through the Spectra series still compete or hold their own against newer speaker designs? I am talking about soundstaging, imaging precision, frequency balance and overall impact.
