For many years I was using a pair of these as a buffer in my HT Omega Claro Halo XT soundcard in combination with a pair of AD797 on the I/V stage. Currently I am using it in the FX-Audio Tube-03 tube preamp in combination with the OPA1622 on the output. Also tried it with some other components. The common experience with this opamp is that it makes sound warm and dark. The sound has nice depth. It also produces/adds full meaty bass. Now, if you prefer bright and/or analytical sound with tons of details and bright vocals, then maybe this opamp will not suits you. Overall this is a very musical, warm and nice sounding opamp, especially for jazz and light ambient music.
