Just finished my review of the V5i, overall quite a good opamp: http://www.head-fi.org/products/burson-audio-supreme-sound-opamp-v5i/reviews/17179
Just replaced my portable amp (bMac 3CH MK2) Output Buffer Op-Amp JRC4556 with Burr Brown OPA2132PA. Right away noticing better soundstage, slightly recessed mids, and slightly brighter treble extension. will have to try OPA2132PA in place of the Gain Op-Amp NE5532, too.
Would MUSES8920 be a good replacement for the gain op amp, and OPA2132 to output buffer?
Well, I'm not sure OPA2132 was designed to be used as output buffers directly connected to headphones, though I don't know bMac's internal schematic. Technically speaking JRC4556 might be safer as output buffer I'd say. I would choose the OPA2132 for the gain stage instead, it has been proved it sounds very well in several headamps. MUSES8920 and also MUSES8820 should sound very well too in gain stage and their internal noise is lower then the NE5532, so feel free to give'em a try.
I suggest Mouser or similar stores for MUSES 8820 and you van also find OPA1688 and adapters for them, in case you feel like upgrading the output buffers (more about thjis http://www.head-fi.org/t/616331/o2-amp-odac/5205#post_12947025
