 IC-based op amps are used in audio for several reasons...ease of design;  ease of assembly; and their low cost…
but not sound quality.   IC-based op amps suffer from EMI noise, inconsistent quality and were NEVER designed for audio.
However, the "discrete" op amp modules from BURSON AUDIO are !
Featuring:
- a sophisticated Voltage Differential Amplification network 
- audio-grade transistors, 1% resistors and a gold-plated pcb 
- 34 parts per single module; 68 parts per dual module 
- meticulously hand assembly
- stringent testing, burn-in and matching procedures
....these modules dramatically exceed the subjective (sound quality) and objective 
(test measurement) performance of any IC-based op amp.
Simply the best op amp in the world !
