Another vote for Khozmo/Hattor. Arek's latest passive using reed relays as opposed to a stepped potentiometer is fantastic (Takman REX/AMRG resistors) . My former passive was a Slagle/Intact audio autoformer pair (a fine sounding unit in its own right). My last active pre was a Berning ZOTL Pre One. I have used Berning amplifiers for the past 25 years.
