Got a pair of double SSV5i and used them in the I/V section of the sound card. Until now I’ve tested a lot of OP-AMP’s, some very good, some very bad, but these are gonna stay forever ( or until a v6i will appear ). With an OPA2132PA in the buffer section the sound is incredible good. Black background and lot of details. These are the best OP-AMP’s I ever tested and I’ve tested a lot, including Muses 01 and 02.
