BJ,
I have Nuforce Ref 9V3SE mono amps w/TDSS Level 3 upgrades and the sound with the Double Impacts leaves nothing to desire further. Used these amps with 5 different systems and speakers since getting the upgrades. The results were the same with all 5, including the Bill Dion (grannyring) parts and driver upgraded version of the DI's. The sound instantly became so dynamic, with great presence, and bass that had major impact and clarity. The Ref 9's were already very nice sounding amps, but the TDSS upgrade made them much greater in all ways. SS amps may be THE way to go with the DI's--at least this pair of amps.
Best regards,
Bob
