Because we are here in order to speak to Grundig's experiences and other one, let me introduce the Amplifier SONY VFET TA 4650.

It's not at all a CCI amplifier, but if you consider that you can also tast some other flavors ... my advice is : try it !

You will find with google a lot of information :

"V-Fet is the acronym for the newly developed vertical type field effect power transistors used in the TA-4650 amplifier.
A V-Fet has extremely low output impedance and excellent high power capability, delivering an output current proportional to input voltages and assuring virtually distortion free amplification.
Use of the V-Fets in the power output stage results in a quality of reproduction hitherto not available to audiophiles"

Less transparent, and accurate than any CCI amplifier (especially for the notes ending and small silences), the Sony is able to play a very nice music with an amazing and natural sound.

If you buy this amplifier, it will need a little inspection to ensure it will work reliably and safely
