A simple idea of using transformers as impedance adapters between TES and conventional JFET amplifiers, allowing to built an electronic readout system that does not degenerate the signal, will be presented. The theoretical modelling and systematic experimental results of such devices, indicate that there is a frequency range were the amplifier noise is negligible with respect to the TES noise.
