Nichicon Muse KZ+(BB OPA2132P + Siemens b32560)=excellent!

Been fiddling around with the output stage of a DAC recently trying to find an optimal synergy between op-amps, 0.1 V rails bypass cap, de-coupling and output caps.
I began with BG FK's and tried to mach them to various op-amps.
The BG's being hard and thin sounding, (used ones), made it quite hard to mate with fancy, fast, lean sounding op-amps, the likes of LM6172, AD826 etc.
I than settled for the OPA2134AP, and the LT1361.
The FK's+OPA2134 gave a detailed smooth sound, but overly warm, and the sound stage was quite flat.
So I replaced the FK's with Nichicon Muse KZ's, which gave a smooth, full bodied detailed yet somewhat slow sound, Than I began rotating op-amps, bypassing their V rails with .1 siemens b32560 cap, about this cap; It's the best IMHO for that job for the simple reason that it has no sound (credits to Thorsten).
When the OPA2132P were put in place I could'nt stop smiling, I struck gold. Sound was extremely natural extended and dynamic, speed and pace were accurate, There was plenty of details without any annoying analysys, I could also here the fans (air) flowing in the concert hall during remissions which gave sense of the halls actual volume. Vocals sounded fantastinc in their tonal accuracy, and even authentic 17th century Baroque playing insturmens were so real to the ear. Nice combo IMHO FWIW.
