Nagra Jazz


Hi,
hopefully someone can answer the following Nagra Jazz questions for me. I have been told that there are optional transformers which can be build in the Nagra and have a positive effect on the sound. Has anyone done this? Another question: is there anybody who uses the Jazz in combination with Spectral power amps?
Thank you for your input!
Cheers,
Wim

Thank you Jfrech!
Luckily the VFS were included in the deal. As for the power supply, both the Jazz and CDP include  the Nagra ACPS II power supply. Now only one thing to do...sell my Spectral 360s and buy the Classic.
Enjoy the festive season!

This is a quote from their brochure on Nagra's website:

"The unit operates in pure class A over a very large power band and beyond in class AB. Each of the output stages is based on tandem MOSFET transistors of exceptional characteristics. Generally, assembly of
an equivalent output stage requires several pairs of transistors, which is difficult to achieve precisely. The simplicity of the CLASSIC AMP’s design is the key to its musicality. The input and driver stages also contribute equally to the overall performance and precision.

The Nagra CLASSIC AMP is characterised by its stability, irrespective of the loads placed upon it. The power circuits drew particular care in the design stage. They are based upon an innovative concept: An over- dimensioned transformer and a diode bridge are placed upstream of the PFC decoupling stage, used to actively correct the power factor. The filtering is achieved with a bank of capacitors, totalling 300 000 μF.
