Hattor Audio Tube Active Stage

The Hattor Audio Tube Active Stage is specifically intended for use with the Hattor Audio Ultimate Passive Pre (The Big).  The price for the unit, $1,900, is in addition to the price for the passive preamp.  However, you can use this unit as a standalone buffer/gain stage with other passive preamps, or as the buffer for a component with very weak output.  

The Tube Active Stage uses the finest parts available from Amtrans, including their Golden Black PIO capacitors, a toroidal power transformer, AMRG resistors and quality jacks (either RCA or XLR).  The stage has sufficiently low output impedance to drive two power amplifiers.
