The sound level from the Creek OBH-10 and Placette RVC should be about the same, since neither has any gain. They both act as attenuators of the signal from your source. I think you will appreciate the sound quality of the Placette as major improvement in your system. You can get an in-home trial if you buy a new Placette, so there isn't any risk.
I was going to get the RVC, but a Passive became available locally. Let me know if you want more details.
