oday, I share my impressions of the sonic improvements enjoyed by the overachieving, über affordable Fosi V3 monoblock amplifiers after replacing the stock Texas Instrument NE5532 IC Op-Amps on their boards with a pair of the SparkoS Labs SS3602 Discreet Dual Op-Amps.
In early November, with one of my “Second Space” episodes, “E199, The Amazing, Affordable Fosi Audo V3 Amplifiers,” I introduced you to the ridiculously good sounding, über affordable, set of minuscule V3 monoblocks from China’s Fosi Audio, built around the Texas Instruments Class-D amplifier chip, the TPA3255.
