Musica Bella
 "Passion"
Line/Headphone Preamplifier

by Response Audio

The Circuit

The Passion preamplifier utilizes a low mu 12AU7 input stage feeding two 5687's in a zero gain buffer output stage that is capable of directly driving most lower impedance headphones.  A switch located on the front panel allows switching between line level and headphone output.

Each Passion preamplifier is handcrafted of the finest materials and top quality parts including Clarity Cap capacitors, military-grade DALE metal-film 1% resistors, Dale 3% wire-wound resistors, Copper/Teflon internal signal wiring and more.

The Chassis

The chassis follows suit of all of our Musica Bella products.  The chassis design allows for quick and easy tube rolling with the tubes accessible through the top. The chassis is constructed of a combination of veneered Baltic Birch and acrylic. For those looking for a the beauty of hardwood, we also offer solid hardwood finished chassis'. As with all Musica Bella products, the Basis is custom built to meet your personal needs and preferences. In this single chassis designs, the power supply is separated from the main circuit by an aluminum shield. The standard single chassis measures 15" x 12" D x 4" H. 

The Sound

The Passion provides a clean yet full sound bringing emotion back to your listening experience. With the zero gain tube buffer output stage, you will fall in love with all your music all over again.
