  • when music wake up your emotions 

  • when music touch your soul 

  • when music fill your room 

  • then be sure you enjoy the DaVinciAudio sound

DaVinciAudio built amplifiers with following design criteria:
 

  1. 1. The particular components of these amplifiers are single ended triode design
    2. Class A operating points
    3. Continuous interstage transformer coupling
    4. Developed for each individual tube and hand-made in our     own atelier
     5. Consistent point to point copper wiring
     6. The C-core transformers consist of a high nickel part
    7. The transformers are encapsulated in MuMetal cans to reduce electromagnetic disturbances
     

  2. All this provides a highest level of audio performance – authentic reproduction of Soundstage in superior class.

MC-Phono Stage-RC-RIAA
 

 

The basic version of the MC-Phono Stage consists of two-stage single ended triode design with continuous interstage transformer coupling and a passive RC-RIAA.

An external regulated power supply without rectifier tube completes the system.

Possibility of extension 1:

MC-Phono Stage in combination with the  LCR-RIAA Driver

 

By adding a Phono Module “LCR-RIAA” you receive a tree-stage single ended triode design with continuous interstage transformer coupling and a passive LCR-RIAA.

 


An external regulated power supply without rectifier tube completes the system.

Other possibility of extension 2:

one Majestic-Power-Supply for the MC-Phono-Stage

To achieve better results you can exchange the standard power supply with the exceptional Majestic Power Supply.

In this configuration each tube has its own power supply.

The power supply have rectifier tube, special high voltage capacitors and a regulated anode potential.

The result is a complete Dual Mono Concept, a new way in a musical dimension.

Example to extend step by step:

The basis version of the MC PhonoStage RC-RIAA consists on a 2 stage circuit, with a passive RC-RIAA.  
The first tube is a 6c45 / the 2nd tube is also a 6c45.
The MC step up is integrated (adjustable with RX jack).

In a 2nd  step you can upgrade this basis amplifier with LCR-RIAA driver.

In a 3th step you can exchange the basis power supply with the Majestic Power supply. This is the highest version of the Preziosa PhonoStage.

With this step you reach the fantastic musicality of the “Grandezza”.

Each modul of this PhonoStage works with other brand.

PreAmplifier

 

 

 

 

The basic version of the PreAmplifier consists of one-stage single ended triode design with continuous interstage transformer coupling and a transformer potentiometer.

An external regulated power supply without rectifier tube completes the system.

Possibility of extension 1:

PreAmplifier in combination with the 300B-Line-Driver

By adding a "300B Line Driver" to the basic version you receive a two-stage preamplifier with single ended triode design and continuous interstage transformer coupling with transformer potentiometer.

In combination with our C-PSE 300B Amplifier you reach a tree-stage circuit design which looks for its-same...

An external regulated power supply for the extension module without rectifier tube completes the system.

Other possibility of extension 2:

one Majestic-Power-Supply for Preamplifier

and

one Majestic-Power-Supply for the 300B Line Driver

Example to extend step by step:

The basis version of the PreAmplifier consists on a transformer potentiometer and a one stage circuit  with  a 6c45 tube.

In a 2nd step you can upgrade this basis PreAmplifier with the 300B Line Driver. So the PreAmplifier is a perfect Driver for the Concept PSE-300B.

In a 3th step you can exchange the basis power supply with the Majestic Power supply. This is the highest version of the Preziosa PreAmplifier.

With this step you reach the fantastic musicality of the “Grandezza”.

Each modul of this PreAmplifier works with other brands.

 

Mono C-PSE-300B Amplifier
 

  

The basic version works only together with our PreAmplifier as Driver ... or with the mono Driver Module

An external regulated power supply without rectifier tube completes the system.
