Curious to know if anyone has experimented with different DOA for a slightly softer/more euphonic tone - like the JLM HS3099. Or if there is any discernible difference with a APP992 or an updated 990 like JLM's or the Sonic Imagery Labs 990Enh vs the Hairball JE990. And has anyone tried swapping the OPA604/2604 in the filter or output stages for DOAs?
Thanks!
