Today's electronically-switched remote-control preamps are a far cry from the manual monsters of 30 years ago, although the basic tube circuits aren't so very different. Conrad-Johnson has painstakingly transformed their performance by moving towards the ideal of zero feedback and using better and better passive components. The PV15 offers a return to the concept of a single-box preamplifier with phono stage built in - unless you choose the line-only option (see boxout). The line-level model costs £2450 and the optional phono section an extra £650.
