Anyone ever use the SP-PASM-2? There's one for sale in the YS and I'm curious as to how it compares to the STC-9000 and STC-9200. I'm very happy with the Church pres. Would I have any use to have the SP pre? The only difference is it appears the SP pre has gain of +29 and +50. Now sure if I would ever need +50db, is this preamp more aimed towards recording very quiet performances?
