The 12AU7 based Spirit is beening revamped for the 2018 model. We have taken away the cost increasing options that most consumers no longer need and focused strictly on the high end sound Musica Bella preamplifiers have become known for over the years Before the official release of the 2018 Spirit, we will be offering a limited run of Spirit 1 standard models at the price indicated at right

The Enhanced version is a transformer coupled fully balanced version with additional enhancement to make it an amazing value. Where else are you going to find a brand new, balanced tube linestage for only $2,300 with all the sonic enhancing features found in the Enhanced.

Spirit 1 - Enhanced Fully Balanced 
  You will be amazed by the performance of this affordable, fully balanced vacuum tube preamplifier. Like the Standard model, the Spirit 1 Special utilize the Class A, Zero Feedback 12AU7 circuit found in our dual mono Lusso models and performs well above it's affordable price indicates. The Spirit 1 Enhanced is housed in the same  chassis as all Spirit models.  Tubes will protrude through the top for easy tube rolling.


The Enhanced model moves up to utilizing transformer coupled balanced inputs and outputs. All single ended connectons are also transformer coupled to maintain a very low output impedance. The inputs will now be handled via a relay based balanced input board. The power supply now encorparates a high current toroidal transformer and is choke filtered.
 
The circuit is based on the 12AU7 dual triode with a constant current source topology.  Signal path components include high precision Carbon Film resistors, Acrylic encapsulated Clarity Cap CSA output capacitors and high quality cryogenically treated, silver plated copper signal wiring. Not a circuit board to be found. All circuits are built and point-to-point wired on 1/8" Micarta boards for resonance control. An Alps Blue volume pot is standard with a Remote Alps Blue w/Mute or Goldpoint Step Attenuator also available

Spirit 1 Enhanced
* Pure Class A balanced vacuum tube purest design

Spirit 1 - Standard Model

Overview. We have come across our inventory of power tranformers that were custom designed and manufactured for Musica Bella Audio so we decided to put together a small run of a very affordable version of the Spirit preamplifier. Take a look at the Spirit 1's Standard Features below to understand why the Spirit could possible be the best sounding preamp you can own for under $3,000
  You will be amazed by the performance of this affordable vacuum tube preamplifier. The Spirit 1 utilize the Class A, Zero Feedback 12AU7 circuit found in our dual mono Lusso models and performs well above it's affordable price indicates. The Spirit 1 is housed in the same rugged aluminum chassis measuring 16" W x 12" D x 3.25" H that will be used for the new 2018 Spirit and Spirit X.  Tubes will protrude through the top for easy tube rolling. If preordered, you can determine the placement of the tubes.
  The Spirit 1 offers a high quality supply originally designed for our Bella Extreme preampifiers with a custom high current IE transformer originally designed for this specific circuit and high quality filter capacitors by JJ Electronics.
The circuit is based on the 12AU7 dual triode with a constant current source topology.  Signal path components include high precision Carbon Film resistors, Acrylic encapsulated Clarity Cap CSA output capacitors and high quality cryogenically treated, silver plated copper signal wiring. Not a circuit board to be found. All circuits are built and point-to-point wired on 1/8" Micarta boards for resonance control.
