i heard the Sussurro on three different tt's at RMAF.
i was in the Soundsmith room three different times. i heard the Sussurro both on the TNT HRX/JPW arm and the Teres Centrus/Illios arm. it was just another cartridge on the HRX; it was something very special on the Teres. i agree that the system in the Soundsmith room is not really up to the potential level of the analog sources in that room.....but i like what i heard on the Teres. nice top to bottom balance, good clarity and boogie factor.....good refinement. a bit opaque on the HRX in comparison.
i also heard it on the Hanss tt in the Lotus Design room (twice) thru the Joe Cohens new speakers. here the Sussurro was not as well behaved as the Teres in the Soundsmith room, but it was still very nice. i would say that this vinyl setup needed some tweaking.
overall i like the Sussurro and i think most people would be very happy with it's performance. OTOH i just got a new cartridge, the Ortofon MC A90, which retails for about the same price. my opinion is that the A90 is in another league or 2 above the Sussurro.
