Six years ago the SP12 was the top selling preamp in the Tubes4HiFi (VTA) product line, almost every person buying a VTA amp was buying the SP12.
But 7 years ago the SP12 got a big brother, the SP14, and in the past 5 years or so the SP12 has almost been forgotten by buyers, as buyers were
no longer looking for a "budget" tube preamp, but the very best tube preamp kit available, the SP14. Maybe 100 SP12s were sold in 4-5 years.
During the past 5-6 years well over 700 SP14s have been sold, more than 7x as many.
