Blackbird is a HO MC, so you only need ~45db of gain. if you want absolute best MC phono stage with >60db of gain and still have a small foot print, Einstein is by far one of the best out there, by a big margin.
Phono PreAmp with less than a 12" x 15" footprint
I refurbished my father's circa 1958 JB Lansing Paragon Speakers, MacIntosh 60 amplifiers (2) and MacIntosh C20 preamp and added an SME 10 turntable and arm and a Sumiko Blackbird cartridge. The weak link is the phono section of the MacIntosh C20. I need to add a phono preamp with a footprint less than 12" x 15" (a comprise with my spouse to keep it "out of sight"). Any suggestions?
