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

Thanks again! Since I am talking to a Nagra expert... why did you sell your PLL and which pre are you using now? Have you ever changed tubes yourself or is this better done by a specialist. At the moment I am offered a second hand jazz, pll and a cdp. A lot to consider...
Only reason I sold the PLL was I fell in love with a preamp that cost 3x the PLL (Robert Koda K10), the Jazz wasn't out yet also.  Was sad to see the PLL go...really liked that preamp.  Any now since I bought a Nagra Classic amp, I could have had a all Nagra system :-)

It's pretty easy for you to change the tubes. Make sure the power is off !!  take to top off (just 4 hex bolts) and the tubes are simply pull out and push in the fresh tube.  Takes just about 2 minutes in total.  (make sure you don't get the tubes mixed up...they aren't all the same types)

I would not buy anything but Nagra tube sets.  They rigorously test and match their tubes.   I've tried others, and always go back to the Nagra factory tubes.   

You might consider a Nagra MPS (multi power supply) to power both your Jazz and CDP.  Should be a nice upgrade down the road.   Also a Nagra VFS (vibration free system) is another very nice upgrade.

Congratulations !!
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!
