All components that is added will affect SQ in my experience. I would be providing documented compensation as this is a start.
FWIW with capacitor bypassing and compensation, latest findings in a Silicon Chip article of there latest M3 100W power amp with On-semi output devices have "discovered" that removing all ceramic capacitors that where used for compensation and stability, reduces distortion in the audio frequency path. This is contarary to there statement made on the use of MKPs and in this article they have opted to use MKPs throughout the design. Very differernt direction compared to there previous offerings and discussions.
In the NAD M51, they are using polystyrene capacitors throughout for compensation on there LME 49990 balance output stage.
