"I’m in love with the new DBoosters by Royer! I predominately record classical music so noise is a real issue. I like to use 2 SF-12’s, one on piano and one for capturing room. However, due to the high gain needed for the Sf-12, I’ve always had to use a low pass filter or employ noise reduction software to clean up the high end hiss. No more!! The dBoosters with 20db of gain allow me to run my preamps much lower, as if I’m using high-output condenser mics, thus cleaning up all the high end hiss. The dBoosters also provide true ground isolation which is essential when working in mid-town Manhattan with all the RFI flying around. If you want to unleash the full potential of your SF-12 and experience all that glorious ribbon sound, the dBoosters are a must have."
