Sparko's Labs has created a family of discrete op amps in an 8 pin DIP
compatible package optimized for high performance audio applications.
These devices are drop in replacements for many common, yet inferior
audio op amps and are uniquely compensated for trouble-free swap out
into virtually any circuit. Having a footprint of a mere 0.33 square
inches, these devices are one-third the size of any other discrete op
amp on the market. Class A biasing and high output current capability
coupled with a two pole compensation scheme requiring multiple NPO
dielectric capacitors make these discrete op amps impossible to
fabricate as a monolithic IC. These devices utilize matched transistor
pairs encapsulated within a single device package for the input stage
and internal current mirrors, which retains the advantage that
monolithics have with device matching.
Installing these devices in place of ordinary IC op amps in your audio system will yield vast performance improvements ranging from quieter or "blacker" background due to their low noise performance, and more detailed, crystal clear highs due to their high loop gain and two pole compensation.

If you are willing to write a review and / or take some pictures of these devices in your audio system, I will accept reasonable offers below list price.
