Unison Reference monoblocs with Unison Reference preamp driving Sonus Faber Stradivari speakers.
Mine were designed and built by a friend. KT-77 driver tubes (or EL34). ECC31 input tubes (or 6N7) Solid state rectification. Huge Magnequest trannies. Built directly on two-inch-thick Mapleshade platforms. Rated at 12wpc by my friend, but I have no trouble driving moderately sensitive speakers (Gallo Reference 3). They're now 10 years and I have no interest in replacing them. Superb-sounding amps.

Preamp is an Aesthetix Calypso.
